Pure Rawz
WorldwideBatch CoAs from a named lab (MZ Biolabs), HPLC-MS, accessible before purchase — but no source verification and openable CoAs date to 2023.
Verified 10/10 of 10 criteria · checked 2026-07-09
Batch-level CoAs from a named lab (MZ Biolabs), HPLC-MS, accessible before purchase. Weaknesses: no lab-side verification, the CoAs we could actually open are dated 2023 (freshness unconfirmable behind Cloudflare), and no sterility data. Manual monitoring.
Is Pure Rawz legit?
On PeptideTrust's 10-criterion transparency scorecard, Pure Rawz scores 75/100 with 100% evidence coverage. That measures how openly it documents third-party testing, not the quality or safety of any product.
Is Pure Rawz a scam?
We make no fraud claim either way — PeptideTrust scores documentary transparency, not criminality. Pure Rawz scores 75/100 with 100% evidence coverage, and the table below links to exactly what we could and couldn't verify. Thin transparency is a reason for caution, not proof of a scam; a high score is not a guarantee of product quality.
Does Pure Rawz do independent third-party testing?
That is exactly what our scorecard measures. Pure Rawz has 10 of 10 weighted criteria verified (100% coverage); each row in the table below links to the third-party certificate, the named lab and the date we checked. Read the evidence rather than trusting a badge.
Criterion-by-criterion evidence
Every score below is a recorded, dated observation. Where we could not verify a claim, the criterion is marked Unverified and excluded from the score (but it still counts against coverage).
| Criterion | Wt | Finding | Evidence |
|---|---|---|---|
| Publishes CoAsThe vendor publishes at least one certificate of analysis (CoA) on its own website. | 3 | ✔ Yes | A dedicated CoA page plus a hosted PDF library (wp-content/uploads). Source · 2026-07-09 |
| Batch-level CoAsCoAs are tied to a specific batch/lot number, not a single generic certificate per product. | 3 | ✔ Yes | Explicit lots (S-4 lot 0049; PT-141 lot PRWZ-083). Source · 2026-07-09 |
| Third-party lab namedThe name of the laboratory that ran the analysis appears on the CoA. | 2 | ✔ Yes | "MZ Biolabs, Tucson AZ" named; analyst Ken Pendarvis, ChE. Source · 2026-07-09 |
| Independent / accredited labThe lab is independent of the vendor and/or accredited (ISO 17025), or is a recognised independent peptide lab (e.g. Janoshik, MZ Biolabs). | 2 | ✔ Yes | MZ Biolabs is a recognised independent US peptide lab (DEA Schedule III); not ISO 17025. Source · 2026-07-09 |
| CoA verifiable at sourceThe CoA can be authenticated on the laboratory's own website (e.g. a verification code) — actually tested, not just claimed. | 2 | ✘ No | MZ Biolabs offers no public verification portal/QR; authenticity only by email to the lab. Source · 2026-07-09 |
| Identity + purity methodsWhich analytical methods are identifiable on the published CoAs. | 2 | ? Unverified HPLC + MS | HPLC-UV (214 nm chromatogram) for purity plus mass spectrometry for identity. Source · 2026-07-09 |
| Freshness of the latest CoADate of the most recent CoA visible on the site. | 2 | ? Unverified > 12 months | The two actually-openable CoAs are dated August 2023 (~3 years); newer CoAs are Cloudflare-403 and unverifiable (not assumed). Source · 2026-07-09 |
| CoAs accessible before purchase, no accountCoAs can be viewed without a customer account or a prior purchase. | 2 | ✔ Yes | PDFs downloaded anonymously, no account. Source · 2026-07-09 |
| Sterility / endotoxin data publishedSterility or endotoxin (LAL) results are published in addition to purity. | 1 | ✘ No | MZ Biolabs excludes sterility/endotoxins/heavy metals; CoA = purity+identity only. Source · 2026-07-09 |
| Public complaints / recall handlingA public recall/complaint policy, or documented handling of a disputed batch. | 1 | ◐ Partial | Community complaints (delivery, support, CoA formatting); no formal recall found. Source · 2026-07-09 |
