The certificate
✅ Its certificate is its own. Peptide Prime commissions its own Janoshik testing: reports such as #151111-#151116 (May 2026) name Peptide Prime as the client, ~99.6-99.8% purity.

Pricing vs the market, benchmarked on BPC-157
| BPC-157 | £1.8/mg (≈ £18 for a 10 mg vial) |
| Versus market median (£3.0/mg) | 0.6×, very cheap |
Suspiciously cheap pricing can signal underdosing or counterfeit material. The Peptide Watch benchmarks every vendor on the same compound, BPC-157, the most common research peptide, as £ per milligram, so prices are directly comparable across all providers.
Payment
🚩 Bank & crypto, bank transfer / crypto only, so if it never ships there is no chargeback to get your money back.
The audit checklist
| Check | Result |
|---|---|
| Verifiable certificate in its own name | Yes, own Janoshik COA |
| Independent lab named | Janoshik |
| Tests its own stock | Yes |
| Pricing vs market | 0.6× median (very cheap) |
The bottom line. Peptideprime earns a place on the independently-tested list because it pays an independent lab (Janoshik) to test its own stock in its own name, and lets you verify it. That is the standard.
