Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You want a straightforward 5 g creatine monohydrate with no sweeteners, dyes, or added sugar.
You are comfortable trusting a brand testing claim without seeing a published Certificate of Analysis.
You want an effective, correctly dosed monohydrate at a mid-range price.
You want a single-ingredient, unflavored creatine monohydrate with no sweeteners or added flavor system.
You want to see published lab results, including a Certificate of Analysis and heavy-metal testing, before you buy.
You want the full 5-gram research-backed dose in one scoop, without measuring or stacking.
You are buying on Amazon, where the roughly 24.99 price for 60 servings makes it one of the lower per-serving options.
The main thing to know
Jacked Factory gets the important things right, a full 5 g of single-ingredient monohydrate at a fair price, but it does not name its creatine source, publish a purity spec, or share any heavy-metal test results, so you cannot independently confirm the powder is as clean as competitors that publish their lab work.
Legion is Labdoor tested and publishes a Certificate of Analysis with heavy-metal results, but it does not carry NSF Certified for Sport or Informed Sport, the banned-substance certifications drug-tested athletes rely on.
Skip this if you...
You want a named, verified creatine source such as Creapure before you buy.
You need published heavy-metal test results to confirm purity for daily family use.
You want a sport certification you can confirm on the certifier's product list.
You are a drug-tested or competitive athlete who needs NSF Certified for Sport or Informed Sport certification.
You specifically want German-made Creapure creatine or a raw-material supplier named on the label.
You prefer a flavored creatine you can mix straight into water for taste.
Neither of these quite what you're looking for?
I've reviewed all Creatine options at every price pointEvery Creatine in our database is scored using R3's deterministic scoring system - the same inputs always produce the same score. For this comparison, we evaluated Jacked Factory and Legion across 3 independent criteria: Safety (85%), Efficacy (14%), Usability (1%). No sponsored rankings. No paid placements.
Straight answers - no sponsored content, no filler.
I'd start with Legion Legion Micronized Creatine Monohydrate - it scored 7.6/10 overall in our scoring system. Safety is our top-weighted scoring pillar, followed by efficacy, and usability. Check which pillar matters most to your family and compare those specific scores.
R3 uses a deterministic scoring system - the same inputs always produce the same score. We evaluate each Creatine across Safety, Efficacy, Usability using independently verified data. No sponsored rankings. No paid placements. Every score is fully reproducible.
Not necessarily. The overall score reflects how we weight those three pillars, but your priorities may differ. If you care most about safety, compare the safety scores directly. If budget drives your decision, the prices tell a clearer story. The "right" pick is the one that matches what matters most to your family.
