Specs are compiled from manufacturer listings and verified buyer reviews and can change over time — please confirm the key details on the product page before buying.
You finish the last set, put the bar down, and then the real question hits: what do you actually take now? An after workout supplement is the powder or capsule you take once training ends, and its only job is to help your muscles bounce back before the next session. The simplest, most-studied option is creatine monohydrate, and the pick most people should start with is the THORNE Creatine — 5g of unflavored powder per scoop, 90 servings per tub, NSF Certified for Sport.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Some picks here are pure creatine, some are amino acid blends you sip during and after training, and one is a full recovery formula with several ingredients in one scoop. Below you get the plain-English version of each, so the after workout supplement you buy is the one built for how you actually train.
Top Picks



How To Choose The Best After Workout Supplement
The hardest part of buying a recovery supplement is that every tub looks like it does the same thing. It does not. Some tubs are a single ingredient in a big bag, some are a flavored drink mix with several aminos, and some are capsules you swallow on the way out of the gym. Decide your goal first, then let the label match it.
Decide if you want creatine, aminos, or a full recovery blend
Creatine monohydrate has the widest research base for strength and muscle support, and every creatine pick here lists 5g per serving. Amino acid blends (BCAAs) are the flavored powders you sip for the taste and to get fluids in during and after training. A blended formula like the Transparent Labs Post combines several recovery ingredients in one scoop. You do not need all three — one consistent daily choice beats a cabinet full of half-used tubs.
Count servings, not tub size
A big tub can still be a short supply. The THORNE tub gives you 90 servings, while the BSN Amino X Fruit Punch gives you 30 — that is a 3.0x gap in how long each lasts at one serving a day. Divide the servings by how many scoops you take daily and you get the real answer on how often you will reorder.
Check the testing line on the label
If you compete in a drug-tested sport, the words that matter are “NSF Certified for Sport” and “Informed Sport Tested” — independent programs that check a batch for banned substances. THORNE, XTEND Sport, and the Sports Research creatine capsules all carry that kind of certification. For a casual lifter it is a nice extra; for a college or pro athlete it decides the purchase.
Match the format to your routine
Unflavored powder disappears into coffee, water, or a protein shake without changing the taste, which is why it is the easiest thing to stay consistent with. Flavored mixes are for people who want a drink they look forward to. Capsules like the Sports Research creatine are for anyone who will not carry a shaker. Pick the format you will actually stick with at 6am on a cold morning.

Detailed Reviews
1. THORNE Micronized Creatine Monohydrate Powder 90 Servings
Our pick — 4.5+★ from 18,500+ verified ratings; the strongest balance of quality and price.
Ninety servings of plain creatine that vanishes into your coffee without a trace.
You get a full 5g of micronized creatine monohydrate in one scoop — micronized means the powder is milled extra fine, so it mixes into your drink instead of sinking to the bottom. That 5g is the everyday amount two household members split in the most-quoted line on the review page: “Hubby and I both take 5 grams a day.” It is unflavored and odorless, so it stirs into warm coffee, a protein shake, or plain water with nothing to mask.
What wins people over here is the powder quality itself — it dissolves cleanly rather than sitting in a gritty layer at the bottom of the glass. The other number to weigh is consistency: this is a daily habit, not a pre-gym jolt, and owners who treat it like brushing their teeth report the steady results. The tub gives you 90 servings, three times the supply of the BSN Amino X Fruit Punch at 30 — worth knowing if you are comparing shelf life rather than single scoops.
The tub measures 8.06 x 4.74 x 5 inches, which is compact enough for a kitchen shelf. The honest catch is the scoop — it sits buried deep in the powder on arrival, so you will dig for it the first time. A small share of buyers also report stomach discomfort, and creatine tolerance genuinely varies from person to person, so start with one serving and see how you feel. For anyone without that sensitivity, it is the least fussy way to get 5g of creatine a day.
What earns its place
- Micronized powder dissolves cleanly in water, coffee, or a shake
- Unflavored and odorless, so it never changes what you drink
- 90 servings per tub stretches a long way at one scoop a day
- NSF Certified for Sport, tested for nearly 300 banned substances
What to know before you buy
- The scoop starts buried deep in the tub
- Stomach sensitivity to creatine is real for a small share of people
- It is a daily habit, not a quick fix you take once
Made for: the lifter who wants one plain, tested ingredient and zero flavor decisions.
Think twice if: you want a drink mix you look forward to — grab a flavored BCAA instead.
2. MuscleTech 100% L-Glutamine Powder Unflavored
The quiet, tasteless add-on for anyone whose soreness outlasts their motivation.
L-glutamine is an amino acid — a building block of protein — and this tub puts 5g of it in every scoop with no fillers or additives mixed in. It is odorless and dissolves into almost anything, which is why it slips into a protein shake or a hydration drink without changing the flavor. At 10.58 ounces it is the lightest tub of the powder picks here, so it travels well in a gym bag.
Buyers keep reordering it for the soreness relief. Buyers describe taking 5g in the evening and noticing less fatigue and fewer cramps during hard training weeks, and it mixes near-clear in four to five ounces of water. Directions call for two servings daily for best results, which is worth flagging — a 60-serving tub at that pace lasts about a month, not two.
One practical wrinkle stands out in the feedback: the container arrives much larger than the powder inside, so reaching the bottom of the tub takes some fishing. It is a mild annoyance, not a reason to pass. For a straightforward, flavor-free amino acid to layer into your existing routine, this is the low-friction choice.
The nightly add-on: unflavored, odorless, and light enough to travel — it joins whatever shake you already drink.
Do the serving math: the label suggests two servings a day, so a 60-serving tub runs out faster than the number suggests.
Reach for this if: you want an inexpensive, tasteless amino acid to stack with creatine or protein.
Look elsewhere if: you prefer a set dose you do not have to measure twice a day.
3. BSN Amino X BCAAs Recovery Powder Fruit Punch 30 Servings
Fruit punch sweet enough to feel like a treat, built for sipping after the last rep.
Each serving delivers 10g of micronized amino acids — the fine-milled building blocks of protein that many lifters sip during and after training. There is no caffeine and no sugar in the mix, so it works as an evening drink without keeping you up. At 15.34 ounces the tub carries noticeably more weight than the MuscleTech glutamine at 10.58 ounces, which tells you there is a real quantity of powder in the container.
The flavor is the whole story here, and it is a love-it-or-not one. Owners describe a sweet-and-sour candy balance that satisfies a sweet tooth mid-session, with more than one comparing it to a certain famous fruit punch drink. The recurring gripe is intensity — it runs very sweet, and a few find it tiring by the end of a shaker. Halving the scoop is the easy fix if you want it lighter.
Here is the practical warning the label does not shout about: do not shake this one. Stirred patiently into 12 to 16 ounces of water it dissolves fine, but shaken it foams up and sprays. Treat the tub like a drink mix, not a shaker bottle experiment, and you get a recovery sip you actually finish.
Why people keep buying it: a caffeine-free, sugar-free aminos blend that tastes like a candy drink rather than a supplement.
How to use it right: stir, do not shake — a patient stir in 12 to 16 ounces of water avoids the foam.
Right for you if: you want a sweet, caffeine-free drink to get your aminos in after training.
Pass if: you prefer a neutral, unflavored powder you can hide in anything.
4. BSN Amino X Recovery Powder BCAAs Grape 30 Servings
The grape version that tastes like soda but drinks like a recovery mix.
Same 10g of micronized amino acids per scoop as the fruit punch, only here the flavor leans toward grape — owners compare it to grape soda, which is why this one gets finished rather than abandoned. The formula lists muscle recovery and muscle endurance support among its jobs, and there is no caffeine or sugar in it. At 1.25 pounds it is a heavier tub than the THORNE creatine at 1 pound, since a full serving of aminos is a bigger scoop than a creatine dose.
Taste is what wins people over — it is far and away the thing this flavor is known for. The reviews also flag a subtle catch: the grape flavor starts to taste odd after about 30 minutes in the shaker, so drink it fresh rather than nursing it through a long session. Slightly concentrated for some palates, best poured over ice. The small tub suits a first-time buyer, and larger sizes exist once you know you like it.
One thing to know about the caffeine-free claim: it means no stimulant in the powder, not that you can stack it carelessly. An owner warns that too many amino acids can set off heart palpitations in sensitive people, so keep to one or two servings on training days. Used sensibly, this is a pleasant way to get fluids and aminos in after a hard session.
The flavor draw: it drinks like grape soda with no sugar, which makes a recovery mix something to look forward to.
Keep it fresh: the grape taste turns odd after about half an hour, so finish the shaker rather than sipping slowly.
Pick this one if: sweet soda-style flavor is what keeps you consistent with aminos.
Not for you if: you want neutral powder for coffee or a protein shake.
5. XTEND Sport BCAA Powder Blue Raspberry Ice 30 Servings
Seven grams of BCAAs plus electrolytes, for the lifter who sweats hard and drinks slow.
Each scoop carries 7g of BCAAs in a 2:1:1 ratio — a specific blend of three amino acids that the brand describes as research-proven, with the numbers built in rather than guessed. Added electrolytes are the second job here: they help replace what you lose in sweat, which is why this one earns the hydration label. The timing is flexible, and the label suggests at least 14g of BCAAs a day across before, during, and after training.
The certification line is the real differentiator on this tub. NSF Certified for Sport is an independent program the label says is recognized by the US Anti-Doping Agency along with major pro sports leagues, so it is built for athletes who get tested. That puts it a notch above a plain BCAA mix for anyone competing at a serious level. There is no sugar in a serving either, which keeps it easy on a day you are already watching intake.
Mixing is straightforward — one level scoop into 10 to 14 ounces of water and shake well, unlike the fruit punch BSN that foams up when shaken. Owners describe it as a drink that makes them actually drink more water through the day, without the tired feeling of a stimulant load. Blue raspberry ice drinks cold and refreshing, and the 30-serving tub is a fair trial size before committing to a bigger container.
Where it shines
- 7g of BCAAs per scoop in a 2:1:1 ratio
- Electrolytes to replace what you sweat out
- NSF Certified for Sport for drug-tested athletes
- Zero sugar and no caffeine
Where it asks more of you
- The label pushes 14g of BCAAs a day, so one scoop may not be enough
- A 30-serving tub is a short supply at two scoops daily
- Flavored mix, so it will not hide in coffee like unflavored creatine
Best matched to: athletes who get tested and want aminos plus electrolytes in one scoop.
One caution: the serving math favors two scoops a day, so plan on a bigger tub.
6. Xtend Original BCAA Powder Watermelon Explosion 30 Servings
Watermelon in a shaker, for runners and lifters who want recovery that tastes like summer.
This is the same 7g BCAA dose and 2:1:1 ratio as the XTEND Sport, in a watermelon flavor with zero sugar and added electrolytes. The 13.2-ounce tub is slightly heavier than the Sport version at 12.2 ounces. The brand also notes the formula suits people on GLP-1 weight-management routines who want to keep muscle and stay hydrated — a use case that keeps coming up in the feedback.
The honest catch with this flavor: it mixes slowly, with specks that float at the top, and the recipe includes FD&C Red #40 — a dye some buyers would rather avoid, and more than one says they will pick a different flavor next time. If that matters to you, the grape BSN above avoids the issue entirely. If it does not, the taste is genuinely a draw and the recovery results hold up.
What keeps people coming back is the recovery — lifters describe far less soreness after hard sessions and no jitters, since the 7g of BCAAs here carry no stimulant. It also stacks cleanly into a shaker with creatine or protein, so it can anchor a stack. At 30 servings it is a one-month supply at a scoop a day.
Why it works: 7g of BCAAs, zero sugar, and a watermelon flavor that keeps runners and lifters reaching for it.
The trade-off: it dissolves slowly and carries FD&C Red #40, which turns some buyers toward other flavors.
Fits the runner or lifter who: wants a sugar-free watermelon drink for post-session recovery.
Skip the watermelon if: artificial dyes are something you avoid — try the grape instead.
7. Optimum Nutrition Creatine Monohydrate Powder Unflavored 120 Servings
A 120-serving tub of plain creatine that just keeps going and going.
Every scoop is 5g of micronized creatine monohydrate, unflavored, so it stirs into a shake or juice without altering the taste. The plain formula lists support for strength, endurance, and lean muscle across progressive training, plus help replenishing energy during hard sessions. At 1.87 pounds the tub is heavier than the THORNE version at 1 pound, and it carries 120 servings versus THORNE’s 90 — the largest creatine supply in this lineup.
Buyers who stick with it describe the powder going in completely, with no clumps and no residue left behind, and a finer consistency that mixes with a spoon rather than a shaker. Strength and fuller muscles show up within the first couple of weeks for many. The one caveat that surfaces is consistency in mixing — a share of buyers find it does not dissolve as cleanly as they want, which is a helpful reminder to stir into plenty of liquid.
What makes this one easy to recommend is patience rewarded: the tub is large enough that the daily habit becomes affordable per serving, and the flavorless format means you never tire of it. The informed choice testing adds a layer of trust for a clean-label routine. If you want the biggest single tub of creatine you can get, this is it.
The long-haul pick: 120 servings of plain 5g creatine — one tub that outlasts most of your other supplements.
Mixing note: it does not dissolve as cleanly for everyone, so stir into plenty of liquid to avoid grit.
For the committed daily user: the largest creatine supply here at 120 servings.
Not the one for you if: you want capsules or a flavored mix instead of a plain powder.
8. BulkSupplements.com Creatine Monohydrate Powder 1KG
A kilogram bag of pure creatine for the lifter who owns a scale and likes to dabble.
This is one single ingredient — micronized creatine monohydrate at 5g per serving — with no flavors, fillers, or blends for anyone to hide behind. The label notes it is made in a cGMP-compliant facility, which means Current Good Manufacturing Practices, a set of production standards for supplements. Because it arrives as a bag rather than a tub, it is designed for people who scoop by the gram with a scale and want the flexibility to set their own dose.
The powder itself is the draw: fine and tasteless, it dissolves into any-temperature water without clumping, and buyers describe weighing out exactly the amount they want — often around 3g a day — without stomach issues. Layered into smoothies or shakes, it disappears entirely. The trade-offs are packaging-level: the resealable bag is harder to close than a tub, and the zipper can clog with powder over time, so it is worth transferring the contents into a container once you open it.
If you already stack creatine with beta alanine or citrulline, this bag is the blank canvas — pure monohydrate you can add to anything without a flavor clashing. You just need the discipline to measure it yourself. For the detail-oriented lifter who weighs everything anyway, the format makes a lot of sense.
The weigh-it-yourself option: a 1KG bag of pure creatine for people who measure their own dose by the gram.
Packaging caution: the bag’s zipper clogs with powder — transfer it to a tub once opened.
Best for: the detail-oriented lifter who weighs each dose and stacks creatine with other powders.
Skip if: you want a fixed scoop and a resealable container that behaves.
9. Sports Research® Creatine Monohydrate Capsules 5g, 120 Count
Creatine you can swallow on the drive home, no shaker or scoop in sight.
Each serving is four capsules delivering 5g of pure creatine monohydrate — the same dose as a scoop of powder, in a format you can toss back anywhere. That makes it the answer for anyone who trains at a gym with no locker room or travels constantly. The label notes the creatine is micronized for better absorption, made without soy, gluten, or artificial ingredients, and carries Informed Sport testing for banned substances.
Because there is no powder to mix, this one sidesteps the taste question entirely — no chalky texture, no grit in cold water. That is a real advantage for anyone who has given up on a creatine tub because they could not stand the residue. The 120-count bottle works out to 30 full servings at four capsules each.
The one thing to plan around is the pill count: four capsules a serving is a genuine swallow commitment, and if you take it daily you will refill the bottle monthly. Compared to the powder tubs here, it costs more per serving for the convenience. That is the trade — you are paying for the format, not the creatine itself.
Why the format wins
- 5g of creatine in four capsules — no shaker, scoop, or water needed
- No taste or grit to deal with
- Informed Sport tested for banned substances
- Made without soy, gluten, or artificial ingredients
What you give up
- Four capsules per serving is a lot to swallow
- A 120-count bottle is only 30 full servings
- Costs more per serving than the powder tubs
Perfect for: travelers and shaker-averse lifters who want creatine with zero prep.
Weigh this: four capsules a serving and a monthly refill for the convenience.
10. Sports Research Collagen Peptides Protein Powder 16oz Unflavored
The scoop that slips into your morning coffee and quietly backs your joints.
Each scoop delivers 11g of low-molecular-weight Type I and III collagen peptides with 18 amino acids, including glycine, proline, and hydroxyproline. Ten grams of protein and 40 calories per serving make it an easy addition to a busy morning. Unflavored and odorless, it dissolves into coffee or a smoothie without changing the taste — which is why it is the most popular thing here.
This is the pick for people whose recovery problems start at the joints rather than the muscles. Owners describe less stiffness after lifting and easier recovery from heavy days, and most of them stir it into their morning coffee.
What reviewers rave about is how completely the 11g scoop dissolves in hot coffee — no clumping, no aftertaste. It is 3rd party tested, Keto Certified, and Certified Paleo Friendly, and free from artificial flavors, sweeteners, dairy, soy, and gluten. If you want a single powder that supports skin, hair, and joints alongside training, this is the one.
The daily habit: 11g of unflavored collagen into your coffee — a routine that covers joints, skin, and hair in one scoop.
Where it fits: joints rather than muscle — pair it with creatine if you lift heavy.
For the joint-first lifter: mix it into coffee and let the routine do the work over time.
Not a substitute for: creatine or aminos if muscle recovery is your goal.
11. Transparent Labs Post – Post-Workout Recovery Muscle Builder with L-Glutamine, Beta-Alanine and BetaPure Betaine Anhydrous – 30 Servings, Strawberry Lemonade
One scoop of several recovery ingredients, for the lifter who does not want to buy four tubs.
This is the only blend in the lineup — it puts several recovery ingredients in one strawberry lemonade scoop: VitaCherry, BetaPure betaine, L-glutamine, and BetaPrime, with the betaine listed as BetaPure betaine anhydrous. The formula also includes Astragin for gut health, and sweetens with stevia instead of artificial sweeteners. At 1.33 pounds it is a compact tub that fits a shelf or a gym bag easily.
The big promise here is convenience — one scoop after training is aimed at supporting recovery and reducing soreness, which is a lot of jobs in one drink. It is naturally flavored and third-party tested for purity and potency. The look and feel of a real formula in one scoop is what draws people who would rather not manage separate glutamine, betaine, and glutamine tubs.
Where a buyer should be honest with themselves is the flavor and value. Taste is mixed — some find strawberry lemonade refreshing, others do not, so buying a smaller supply first is sensible. Because it combines several ingredients, the per-serving cost runs higher than a plain powder. At 30 servings it is a one-month supply. If you want a single scoop to handle a whole recovery routine, it is a fair way to skip the tub collection.
The one-scoop case: glutamine, betaine, and VitaCherry in a stevia-sweetened strawberry lemonade mix — recovery without juggling four tubs.
Try before you commit: the flavor divides people, so start with the 30-serving tub before buying bigger.
Built for: the lifter who wants several recovery ingredients in one daily scoop.
Be honest about: the mixed taste reviews and the higher cost per serving versus a pure creatine.
Know the Specs
Servings Per Tub
Servings tell you how many doses you get — so divide it by how many scoops you take a day to see the real supply length. A 90-serving creatine tub at one scoop daily is roughly three months, while a 30-serving aminos mix at one scoop daily is about a month. It is the cleanest way to compare value between two different tubs and formats.
Dose Per Serving
This is how much of the active ingredient you get in one scoop or serving — 5g of creatine, 7g or 10g of BCAAs, 5g of glutamine, or 11g of collagen. Serious buyers check the dose first, because a big tub with a tiny dose is not the value it looks like. The dose also tells you how much you need to mix into water to get the labeled benefit.
Third-Party Testing
A third-party test means an outside lab checks the batch instead of the brand checking itself. “NSF Certified for Sport” and “Informed Sport Tested” are specific programs that screen for banned substances, while “cGMP-compliant facility” refers to manufacturing standards rather than a product test. If you compete in a drug-tested sport, look for the sport-specific certification before anything else.
Flavored vs Unflavored
Unflavored powders disappear into water, coffee, or a shake without changing the taste, so they are easiest to stay consistent with. Flavored mixes are for anyone who needs the drink to be pleasant to keep it up — but they bring sugar substitutes, dyes, or strong tastes that some buyers dislike. Match the format to the drink you actually enjoy, because the best supplement is the one you will not skip.

The Bottom Line
If you take one thing from this, take this: the after workout supplement that works hardest for most people is the THORNE Creatine, because it is a plain, tested 5g creatine with 90 servings and nothing to figure out. If you want a recovery drink you will actually look forward to, the BSN Amino X Fruit Punch gives you 10g of caffeine-free aminos in a sweet candy-style mix. And for joint-first recovery, the Sports Research Collagen Peptides slips into your coffee with 11g of unflavored collagen. Start with one pick, stay consistent, and let the daily habit do the work.
