No independent test of PureRawz's P21 yet
- We hold no independent tests for P21 from any maker yet — unknown stays visible.
- We couldn't place this listing's price — its size isn't readable or the market's too thin — so there's no cheap-fake check here.
How to verify this yourself
To verify before you buy: ask PureRawz for the Janoshik COA for your batch number, then paste it into Verify — VialGrade confirms it's a real, unedited lab record.

Hands you to purerawz.co — VialGrade doesn’t sell or take payment
Some vendor links may earn VialGrade a commission. It never changes a grade, a price, or where a listing ranks.

Every P21 listing, cheapest per mg first
Sticker prices hide the size, so listings are ranked by what a milligram actually costs — with independently tested purity where it exists. All 3 are here: the last 2 are listings whose vendor never published a strength we can read, so they have no per-mg figure to sort on.

Real $/active mg divides the price-per-mg by the measured purity — the honest cost of the actual peptide, so a 90%-pure vial isn’t compared as if it were 99%. Too cheap? flags a listing far below the market rate — often underdosing or a fake, not a deal. The crown marks the cheapest non-outlier; best value marks the lowest real cost per active mg. A vendor shown as Unavailable or Low stock is priced here but not currently buyable.
Understand this compound
What is P21?
Preclinical / animal onlya.k.a. TFP5 (related fragment)A brain-protection molecule designed to block an enzyme that goes haywire and kills neurons after strokes and in neurodegenerative disease. Animal research only.
Good to know: Research is confined to animal models of stroke and neurodegeneration; no human safety or efficacy data exist.
How does P21 work?
The science
A peptide derived from the CDK5-activating cofactor p35, designed to inhibit pathological CDK5/p25 hyperactivity implicated in neuronal apoptosis after injury or in neurodegeneration.
Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.
What is P21 researched for?
Studied for neuroprotection in ischemic stroke and neurodegenerative disease models, including Alzheimer's and Parkinson's.
- Cognitive & moodStudied in memory, focus, mood, and neuroprotection research.
How far has the research gone?
Preclinical / animal research — efficacy shown in rodent stroke and Parkinson's models (often via the related peptide 'TFP5'), with no identified human trials.
Where the science stands — an approved drug is not the same as the research-grade material a vendor sells, which is unregulated regardless.
What should I check before buying?
- Independent purity. Look for a third-party COA (Janoshik or MZ) showing a measured purity — not just a number the vendor typed.
- Batch match. The strongest evidence is a certificate for the exact batch you’ll receive, attributed to this vendor — check the cross-verification on the listing.
- Vendor reputation. See how the vendor is talked about in the community before trusting a new name.
Research context only — VialGrade never gives dosing, medical, or human-use guidance.
The lab evidence
What we could verify
Each row is a separate question with its own answer — one green row never vouches for the rest.
Identity
UnknownNo independent test on record for this listing.
Measured purity
UnknownNo independent purity measurement on record.
Batch traceability
UnknownNo batch on this listing matches an independent record.
Sterility
Not testedA purity certificate doesn't measure this — no such test on record.
Dose accuracy
UnknownNot something VialGrade measures — no test on record.
No third-party testing to cross-check
This listing doesn't advertise independent lab testing, and we don't hold an independent record for PureRawz's P21. Absence of a certificate isn't proof of anything — but there's nothing here to verify.
- Independent testing. No third-party COA advertised or on record.
Cross-checks the vendor’s testing claim against independent lab records. Read from the certificate, not re-measured by VialGrade. Purity is not a grade. Never a statement that a product is safe, sterile, or correctly dosed. What “grade” actually means

Research-use-only — not FDA-approved
Sold “for research use only,” this compound is not FDA-approved for human use and has not been evaluated for safety, purity, or sterility in people. It is generally not a scheduled controlled substance, so buying it as a research chemical is typically not itself a drug crime — but marketing or using it as a drug is not lawful, and it is not a dietary supplement.
General information, not legal or medical advice. VialGrade sells nothing and encourages no human use.
