Pricing vs the market, benchmarked on BPC-157
| BPC-157 | £2.4/mg (≈ £23.99 for a 10 mg vial) |
| Versus market median (£3.0/mg) | 0.8×, competitive |
In line with the wider UK market. 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.
Reviews
Has a Trustpilot page, but too few reviews for a score.
Read it critically. A Trustpilot score measures whether parcels turn up and support replies, not whether the vial contains what the label says. A vendor can have hundreds of happy delivery reviews and still show you a borrowed or fake certificate; the two are unrelated. Also watch for a burst of near-identical 5-star reviews in a short window, the signature of bought reviews.

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 | 0.8× median (competitive) |
The bottom line. Ck Peptides 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.
