Grade DAvoid — thin evidence

Recent activity: Zero COAs in the last 90 days; latest publication was 681 days ago (~1.9 years stale). Score: D. Score: D (revised from C under recent-cadence-weighted rubric). PureRawz publishes COAs from a real, named third-party lab (MZ Biolabs), and per-product COAs are reachable on each product page (no login required). However: (1) every sampled COA is ≥18 months old as of 2026-05-09 — BPC-157 dates to August 2023, Tirzepatide to June 2024, contradicting their 'every batch tested' claim; (2) MZ Biolabs COAs have no QR/portal verification system — only the lab's email is provided; (3) the same MZ Biolabs template is used by Vigor Peptides (and historically other vendors), so the template alone provides no source-of-truth differentiation; (4) no central COA index page exists — researchers must visit each product page individually. The vendor clears the F bar (real lab, real testing) but earns a C: 'Performative — COAs exist but volume is low [updates], OR all COAs older than 6 months.' Caveat: a deeper crawl across all ~80+ product pages might surface newer COAs not seen in this audit; this score reflects the 3-product sample (BPC-157, S-4, Tirzepatide).

The take

A real lab and real COAs in the archive cannot offset a COA program that effectively went silent in mid-2024.

PureRawz built a real COA program once, then quietly stopped feeding it. The lab on the reports — MZ Biolabs in Tucson, signed by Ken Pendarvis, ChE — is a verifiable third party at a real Arizona address. The sampled documents are real lab work: a BPC-157 COA dated 2023-08-23 (lot PRWZ-051), an S-4/Andarine COA dated 2023-08-21 (lot 0049), a Tirzepatide COA dated 2024-06-27 (lot PRZ-TIRZ). What's missing is anything more recent. As of the 2026-05-09 audit, the latest publicly visible COA is 681 days old. That is not consistent with the site's claim that 'lab reports are updated with each batch.' The domain has been live since February 2019 and the brand has name recognition in the space, which makes the 18-to-30-month gap on a high-traffic site a deliberate gap, not an oversight. The MZ Biolabs PDFs also carry no QR code or portal lookup, so even the historical reports require an out-of-band email to the lab to re-verify.

  • Strength. MZ Biolabs is a verifiable independent lab in Tucson, AZ, and the sampled COAs are signed lab work — not a fabricated template.
  • Concern. Every COA in the sample is at least 18 months stale, with the latest dated 2024-06-27 (681 days before audit), which directly contradicts the 'every batch tested' marketing.

"Every batch" claimed? Yes
Volume vs. claim Site claims 'lab reports are updated with each batch' and '99%+ Purity with Verified COAs', but every COA inspected is 1.5-2.5+ years stale. BPC-157 COA dated 2023-08-23 (lot PRWZ-051), S-4/Andarine 2023-08-21 (lot 0049), Tirzepatide 2024-06-27 (lot PRZ-TIRZ). No 2025 or 2026 COAs observed in product samples — claim of per-batch testing is contradicted by stale dates.

Issuing labs & verifiability

  • MZ Biolabs (Tucson, AZ — 1635 E 18th St, contact@mzbiolabs.com) Unverifiable — MZ Biolabs is a real lab at mzbiolabs.com offering analytical services including HPLC + mass spectrometry. COAs signed by Ken Pendarvis ChE, Analytical Chemist. Lab is independently verifiable as a real entity, but PureRawz COAs do not embed QR codes, batch portal IDs, or any cryptographic verification mechanism — verification requires manually contacting MZ Biolabs.

Authenticity

Bottle images match brand? Unknown / unable to verify
Bottle evidence COAs sampled (BPC-157, S-4, Tirzepatide) display chromatograms and lab metadata only — no vial photographs are embedded in the COA documents. Product page hero images show PureRawz-branded labels (purerawz.co/wp-content/uploads/2022/06/PZ_BPC-157_5mg-1-1.webp), but these are marketing photos, not COA evidence. Cannot confirm or deny that the product photographed in the COA matches the vendor's branding because no vial appears in the COA.
COA template shared with other vendors? Yes
