Obsidian Sciences obsidian Sciences (61 Bridge Street, Kington HR5 3DJ) sells BPC-157, KPV, GHK-Cu, Selank, Semax, TB-500 and ARA-290 with GBP pricing and Royal Mail dispatch, claiming products are 'third-party verified' with 'COA, HPLC ≥99%', but names no laboratory and publishes no verifiable certificate.
See the full audit. This is the short answer; the full Obsidian Sciences dossier has the certificate check with a live verification link, the Companies House record, pricing against the market and the complete checklist.
Obsidian Sciences (obsidiansciences.co.uk) is on The Peptide Watch's watch list. It does not publish a certificate of analysis that can be independently verified in its own name, so its quality claims rest on trust rather than checkable evidence. That is not proof of a scam; it means the evidence does not check out.
You cannot independently verify its testing today. A good delivery reputation is not the same as a verifiable certificate; the two are unrelated. Until Obsidian Sciences publishes an own-name certificate you can check on an independent lab's website, you are taking its quality on trust.
The Peptide Watch does not assert that. What is observable is the reason it sits on the watch list: no named lab, nothing to verify. Being unverifiable is a reason for caution, not proof of fraud.
Not one that can be independently verified in its own name. ⚠ 'Third-party verified COA' but no lab named. Obsidian Sciences claims third-party HPLC verification but names no laboratory.
