For a drug-tested athlete, the creatine decision includes the finished product and its certification record, not just the ingredient name. These ten unflavored powders use creatine monohydrate and have entries in NSF’s Certified for Sport directory. Match your package and lot to the current entry before use; a logo or familiar brand name alone is not enough.
Written by Tom Miller, CSCS. Updated: October 2026.
Short on time? Thorne Creatine is our all-around pick for a simple 5g serving and roughly 90 servings per tub. BPN is a smaller Creapure option; BulkSupplements gives you a 1kg pouch. For competition use, the exact formula and applicable lot record take priority over the ranking.
How We Chose
We start with unflavored creatine monohydrate powders, a clear 5g serving, and a matching finished-product entry in the NSF Certified for Sport directory. We then compare package weight, supply at 5g per day, ingredient simplicity and the certification entry’s lot coverage. A 300g tub and a 1kg pouch serve different buying needs even when the active ingredient is the same. Ratings reflect those criteria, not claims that one brand builds more muscle at the same dose. Named-lot entries require an extra check against your delivered package. Certification reduces risk; it does not make a supplement risk-free or guarantee eligibility under every sport’s rules.
Our Verdict
Thorne Creatine
A straightforward unflavored 5g powder with approximately 90 servings; match the tub and lot to the current NSF record before competition use.
Best for: Adults seeking a simple certified-powder option

Best All-Around: Thorne Creatine
Thorne Creatine Unflavored 90 Servings
Best All-AroundA 450g unflavored creatine monohydrate tub with about 90 servings, suited to a straightforward daily routine once its current certification record matches.
Pros
- 5g creatine monohydrate per serving
- 450g tub with about 90 servings
- Unflavored formula
Cons
- Named-lot certification entry requires matching
- Separate travel packs and flavored products have different records
Thorne’s 450g tub gives you about 90 daily portions at 5g. That is a useful middle size between BPN’s 300g tub and BulkSupplements’ 1kg pouch. The simple formula also avoids adding a flavored drink or pre-workout blend to your supplement list.
Use the NSF powder record covering 450g and 900g packages, then match the lot. Thorne’s travel sticks have a separate record. Skip this if you cannot confirm the delivered lot or only want a shorter initial supply. BPN’s 60-serving tub reduces that initial quantity; a larger Thorne tub does not change the 5g portion.
Best Alternative 90-Serving Tub: Momentous Creatine
Momentous Creatine Unflavored 90 Servings
Best Alternative 90-Serving TubA 450g, 90-serving unflavored powder with a simple ingredient panel; compare its delivered price and current certification against other 90-serving tubs.
Pros
- 5g serving with no other ingredients listed
- 450g and 90 servings
- Unflavored powder record lists all lots
Cons
- A second 90-serving option, not a proven efficacy upgrade
- Chews and flavored powders are separate products
Momentous gives you the same 90 portions of 5g as the selected Thorne tub. Its current Signature Spec label lists creatine monohydrate with no other ingredients. That keeps the serving calculation simple: 450 divided by 5 equals 90.
The unflavored powder’s NSF entry lists all lots and includes the 450g size. Check that you are buying this powder rather than assuming a flavored powder or chew shares the record. Skip this if its price premium over another matching certified 5g powder does not buy anything you need. A larger marketing claim is not evidence of more strength gains at an equivalent creatine dose.
Best 315g Option: Klean Athlete Klean Creatine
Klean Athlete Klean Creatine 315g
Best 315g OptionA smaller 315g unflavored tub, equal to about 63 portions at 5g, with its own package and lot record to check.
Pros
- 5g creatine monohydrate serving
- 315g package gives about 63 portions
- Unflavored formula
Cons
- Named lots require confirmation
- Use the package's measure rather than assuming every scoop is equivalent
Klean’s 315g tub works out to approximately 63 portions at 5g. It sits close to BPN and Creature’s 60-serving tubs rather than the 90-100-serving choices. The matching NSF entry specifies the 315g unflavored powder and a 5g serving.
The directory expresses that serving as 1.5 teaspoons, so do not transfer another brand’s scoop measure to this product. Follow the current package’s directions. Skip this if you want a longer supply from one purchase or cannot match the named lot. MegaFood’s 500g tub contains about 37 more 5g portions, while BPN gives a similar initial supply in a 300g tub.
Best for Ingredient Exclusions: MegaFood Creatine
MegaFood Micronized Creatine Monohydrate 500g
Best 100-Serving Allergen-Exclusion OptionA 500g unflavored powder with 100 servings and manufacturer allergen-exclusion claims, for buyers who need to examine both certification and ingredient restrictions.
Pros
- 5g creatine monohydrate per serving
- 500g and 100 servings
- Manufacturer states made without nine major allergens
Cons
- Allergen-exclusion claims do not settle individual allergy safety
- Named certification lots require matching
MegaFood’s 500g tub supplies 100 portions at 5g, ten more than the selected Thorne or Momentous tubs. The brand identifies a single creatine ingredient and states that the product is made without nine major food allergens. Those claims can help narrow your shortlist, but they do not replace advice about a diagnosed allergy.
The NSF entry matches the 500g unflavored powder and names specific lots. Skip this if your delivered lot does not match or you need more detailed cross-contact assurance. Muscle Milk gives you the same 100-portion quantity; compare the exact labels and checkout totals rather than assuming MegaFood’s micronized wording establishes a better training result.
Best 90-Serving Creapure Tub: BUBS Boost
BUBS Boost Creatine Monohydrate 90 Servings
Best 90-Serving Creapure TubA 450g Creapure-based tub with 90 daily 5g portions, for buyers who want both a named raw material and matching sport certification.
Pros
- 5g Creapure creatine monohydrate
- 450g and 90 servings
- Unflavored single-ingredient formula
Cons
- Named lots require confirmation
- A Creapure mark alone is not finished-product sport certification
BUBS Boost combines a named Creapure raw material with a 450g, 90-serving tub. At 5g per day, that is 30 more portions than BPN’s selected 300g Creapure tub. The larger BUBS tub lasts another 30 days at the same daily portion.
The BUBS Boost NSF entry covers the unflavored powder and lists named lots. Match your tub rather than treating the Creapure logo as a substitute for this check. Skip this if you prefer a smaller first purchase or cannot confirm the lot. Sports Research is another 450g Creapure option, while BPN reduces the initial supply to 60 portions.
Best Alternative Creapure Tub: Sports Research Creapure
Sports Research Creapure Creatine 90 Servings
Best Alternative Creapure TubThe 90-serving Creapure version of Sports Research creatine, with a separate identity from the brand's familiar 100-serving monohydrate powder.
Pros
- 5g Creapure creatine monohydrate
- 450g and 90 servings
- Distinct finished-product NSF listing
Cons
- Specific lot coverage needs checking
- The 100-serving non-Creapure tub is a different product
Buy the 90-serving Creapure version, not a different Sports Research tub based on the black packaging alone. This selected product contains 450g with a 5g portion. The brand’s 100-serving non-Creapure powder is a separate purchase and has its own certification identity.
The Creapure-specific NSF entry names lot 26174B at this update. Recheck the live record before use because listed lots can change. Skip this if your package is a different formula or lot and the manufacturer cannot confirm coverage. BUBS gives you the same 450g quantity; compare verified eligibility and actual per-serving cost rather than assuming one brand’s 5g dose is stronger.
Best Smaller Creapure Tub: BPN Creatine Monohydrate
BPN Creatine Monohydrate 60 Servings
Best Smaller Creapure TubA 300g unflavored Creapure tub with 60 servings, useful when you want a smaller initial supply without switching to capsules or flavored blends.
Pros
- 5g creatine monohydrate from Creapure
- 300g and 60 servings
- Unflavored powder record lists all lots
Cons
- Smaller supply than 90-100-serving tubs
- Brand also sells different sizes and formulas
BPN’s selected tub contains 300g, enough for 60 portions at 5g. That is two-thirds of a 450g tub’s supply. It makes sense when you want a smaller initial purchase, though the smaller container does not automatically make the cost per serving lower.
The unflavored BPN record includes the 300g size and lists all lots. Keep the product identity precise; this is plain Creatine Monohydrate, not a multi-ingredient performance blend. Skip this if you want a long supply with fewer repeat orders. BUBS and Sports Research give you another 30 portions in their selected tubs.
Best Alternative 100-Serving Tub: Muscle Milk Pro Series Creatine
Muscle Milk Pro Series Creatine 100 Servings
Best Alternative 100-Serving TubA 500g unflavored creatine powder supplying 100 portions, clearly distinguished from Muscle Milk's separate protein drinks and protein powders.
Pros
- 5g creatine monohydrate serving
- 500g and 100 servings
- Unflavored powder record lists all lots
Cons
- Brand name can be confused with its protein powders
- Large tub is less convenient than single-serving packs
Muscle Milk Pro Series Creatine contains 500g, equal to 100 portions at 5g. Its name does not make it a protein shake: this is the separate creatine powder. The matching NSF record identifies the 500g unflavored product and lists all lots.
It gives you the same portion count as MegaFood and ten more than Thorne’s selected tub. Skip this if you need individual travel portions or intended to buy protein as well as creatine. You would still need to plan protein from food or a separate product. Compare the 100-serving price with MegaFood after checking the delivered product’s current label and certification identity.
Best Additional 60-Serving Option: Creature NSF Certified Creatine
Creature NSF Certified Creatine Monohydrate 60 Servings
Best Additional 60-Serving OptionThe plain 300g NSF-listed Creature monohydrate powder, not its separate five-form creatine complex; match the product name and applicable lot before use.
Pros
- 5g creatine monohydrate serving
- 300g and 60 servings
- Separate NSF-certified plain-powder identity
Cons
- Named-lot coverage needs confirmation
- Creature's five-form creatine complex is a different product
Creature’s plain NSF Certified Creatine Monohydrate tub contains 300g and 60 servings. It is a different formula from the brand’s five-form Creatine Complex. Similar branding does not make the complex equivalent to this single-ingredient powder.
The plain powder’s NSF entry names lot 2505070 at this update. Skip this if you cannot confirm that your lot is covered, or the retailer selects the complex instead. BPN gives you the same 60-portion supply with a named Creapure ingredient. Choose between them by confirmed lot coverage and the delivered cost per 5g.
Best Large Pouch: BulkSupplements Creatine Monohydrate 1kg
BulkSupplements Creatine Monohydrate 1kg
Best Large PouchA 1kg unflavored pouch with about 200 daily 5g portions, for established routines where the exact delivered lot matches the certification record.
Pros
- 1kg supplies about 200 portions at 5g
- Unflavored creatine monohydrate
- Matching NSF entry includes 1kg packages
Cons
- Named lots require confirmation
- Large pouch is a bigger initial commitment
The selected 1kg pouch contains about 200 portions at 5g, twice the quantity of a 500g tub. It is the largest supply here. That can reduce repeat orders, but a large package only makes sense after you are comfortable with the product and its certification coverage.
The NSF unflavored-powder entry includes 1kg among the package sizes and names specific lots. Match both; a broadly worded testing claim for a brand is insufficient. Skip this if you cannot verify your lot or prefer a smaller initial quantity. BPN’s 300g tub contains 140 fewer portions, so compare cost per 5g rather than pouch price against tub price.

How to Buy Creatine for Drug-Tested Sport
Verify the Finished Product and Lot
Open the current NSF entry for the exact powder. Match the name, package size and formula, then check the lot field. Some records list all lots; others name individual lots. Sports Research’s Creapure version has a different entry from its non-Creapure powder, and Creature’s plain powder differs from its complex. Keep the label and purchase details. If a match is unclear, ask the manufacturer or your sports-nutrition professional before using it for competition.
Understand What Certification Covers
NSF describes checks for label contents, contaminants and prohibited substances or masking agents. That is useful risk reduction, not a promise of a clean drug test. USADA advises athletes that no supplement is 100% risk-free. A raw-material logo, a general NSF facility claim or certification on another product from the brand does not establish coverage for your tub. Confirm your governing body’s current requirements as well.
Compare the Same 5g Portion
The selected packages range from 300g to 1kg. At 5g daily, BPN and Creature give you 60 portions, Klean about 63, the 450g tubs about 90, the 500g tubs 100, and BulkSupplements about 200. A hypothetical $30 tub with 60 portions costs 50 cents per portion; a hypothetical $40 tub with 100 costs 40 cents. These are arithmetic examples, not current prices. Our creatine capsule comparison uses a different pill-count calculation.
Keep Dose and Routine Simple
The ISSN position stand describes 3-5g daily as a common maintenance amount after muscle stores are saturated. Follow your product’s directions and individual advice. A loading phase is optional and changes how quickly stores rise, not the need for an adequate ongoing routine. Do not double your portion because a new tub has a different scoop. Use the label’s gram amount, and compare with our Creapure creatine guide if named raw-material sourcing is a separate priority.
Separate Creatine From the Rest of Your Stack
A matching creatine product does not establish the status of your pre-workout, protein powder or recovery blend. Check those separately. Our protein powders for drug-tested athletes guide covers another category. Adults with kidney disease, pregnancy, breastfeeding, medication concerns or other medical conditions should discuss creatine with a qualified clinician. Certification does not determine whether a supplement is appropriate for a particular medical situation.
Frequently Asked Questions
Does NSF Certification Guarantee I Will Pass a Drug Test?
No. It reduces a specific set of supplement risks, but no testing program can remove all risk. Match your exact formula and applicable lot to the current record, then follow your sport’s requirements. Do not treat an Amazon title, package logo or a different product from the same brand as a substitute for that check.
Is Creapure the Same as NSF Certified for Sport?
No. Creapure identifies a branded creatine monohydrate raw material. NSF Certified for Sport identifies a finished-product certification program. BPN, BUBS and the selected Sports Research version combine those attributes, but you still need the exact product record. A Creapure mark by itself does not establish sport certification for the finished tub.
Which Package Lasts Longest?
The selected BulkSupplements 1kg pouch gives about 200 portions at 5g. A 500g tub gives 100, a 450g tub about 90, and a 300g tub 60. Those figures assume 5g portions and do not include a loading phase, spills or a different individual dose. Compare grams of powder and the serving directions, not tub height.
Do I Need a Loading Phase?
No. Loading is an optional way to increase creatine stores faster. A consistent lower daily intake builds stores over a longer period. Follow the package and your sports-nutrition professional’s advice rather than treating a loading phase as mandatory. Discuss dosing with a clinician when medical circumstances make supplement use more complicated.
Are Flavored Powders and Gummies Covered Too?
Not automatically. The records linked here apply to the named powders, with their stated package and lot details. A flavored product, gummy, chew or multi-ingredient blend can have a different record or no matching entry. Search that exact product separately rather than transferring the certification from a plain powder.
Bottom Line
Thorne is our all-around choice for a simple unflavored 5g routine in a roughly 90-serving tub. BPN suits a smaller Creapure purchase, while BulkSupplements gives you the largest supply. At equal doses, these products use the same active ingredient; choose by verified eligibility, package size and real cost per serving. Confirm your delivered formula and lot before competition use. Certification reduces risk, but it does not remove it.
