EURegena Peptides is a Spain-based EU research-peptide vendor that publishes an open library of batch-specific Janoshik Analytical certificates of analysis.
Verified 10/10 of 10 criteria · checked 2026-07-27
Regena Peptides operates a public, no-login CoA library at regena-peptides.com/coa containing dozens of Janoshik Analytical reports, each tied to a specific batch/lot and carrying a Janoshik verify key and HPLC+MS purity figures. The catalogue extends beyond purity to endotoxin (LAL) and heavy-metals safety panels, and the most recent certificates are dated May 2026. Independent authentication of the verify keys could not be completed because Janoshik's verification portal blocked automated access, and no public recall or complaints policy was found.
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 | Dedicated public CoA library hosting dozens of Janoshik reports as signed CoA images, each linked to a downloadable file. Source · 2026-07-27 |
| Batch-level CoAsCoAs are tied to a specific batch/lot number, not a single generic certificate per product. | 3 | ✔ Yes | Each CoA is tied to a specific batch/lot (e.g. Tirzepatide 30mg batch 1102, GHK-Cu LOT#0709, TB-500 #0816); site states 'Every order includes the COA for the exact vial shipped.' Source · 2026-07-27 |
| Third-party lab namedThe name of the laboratory that ran the analysis appears on the CoA. | 2 | ✔ Yes | Testing lab named on CoAs as Janoshik Analytical (janoshik.com); a few specialised panels reference VidaLabs (USA). Source · 2026-07-27 |
| 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 | Janoshik is a recognised independent EU peptide-testing lab described as operationally independent from manufacturers; no ISO 17025 accreditation claimed or confirmed. Source · 2026-07-27 |
| 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 | ◐ Partial | Each CoA carries a 12-char Janoshik verify key (e.g. MLMITMZ31PEL) checkable at janoshik.com/verify; the Janoshik verify portal returned HTTP 403 to automated access so an actual authentication lookup could not be completed. Source · 2026-07-27 |
| Identity + purity methodsWhich analytical methods are identifiable on the published CoAs. | 2 | ? Unverified HPLC + MS | CoAs identify HPLC + MS as the primary method; additional immunoassay (HCG), LAL (endotoxin) and MS (heavy metals) panels also shown. Source · 2026-07-27 |
| Freshness of the latest CoADate of the most recent CoA visible on the site. | 2 | ? Unverified < 3 months | Most recent CoAs dated 12-13 May 2026 (e.g. AOD-9604, Tirzepatide 60mg, PT-141), under 3 months before 2026-07-27. Source · 2026-07-27 |
| CoAs accessible before purchase, no accountCoAs can be viewed without a customer account or a prior purchase. | 2 | ✔ Yes | Full CoA library is openly viewable without any account, login, or prior purchase. Source · 2026-07-27 |
| Sterility / endotoxin data publishedSterility or endotoxin (LAL) results are published in addition to purity. | 1 | ✔ Yes | Published safety panels include Endotoxin Analysis (LAL) reporting 1.991 EU/vial and Heavy Metals 'not detected'; note the trust page clarifies CoAs do not certify sterility. Source · 2026-07-27 |
| Public complaints / recall handlingA public recall/complaint policy, or documented handling of a disputed batch. | 1 | ✘ No | No public recall or complaints policy or documented disputed-batch handling found (a separate refund policy is linked). No FDA warning letters or CoA-fraud red flags identified for this vendor. Source · 2026-07-27 |
