Opti Peptides opti Peptides (matching Opti Peptides Ltd, Companies House 16852554) is now trading: a live catalogue of 20+ products (Retatrutide 10mg £74.99, SLU-PP-332, MOTS-c, bac water) with GBP pricing and rapid UK shipping. It says products are 'verified through appropriate testing and quality-control standards' but publishes no COA and names no laboratory.
See the full audit. This is the short answer; the full Opti Peptides dossier has the certificate check with a live verification link, the Companies House record, pricing against the market and the complete checklist.
Opti Peptides (optipeptides.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 Opti Peptides 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. ⚠ Registered UK company, but no COA and no lab named. Opti Peptides Ltd (Companies House 16852554) has a live catalogue but only claims 'appropriate testing', with no COA and no laboratory named.
