Is Thoroughbredlabs legit?
thoroughbredlabs.co.uk · audited 1 July 2026
✅ Independently tested, its certificate is genuinely its own and verifiable.
Thoroughbredlabs publishes its own Janoshik certificate of analysis, naming Thoroughbredlabs as the client, with its most recent certificate dated Sep 2025. Because Janoshik reports carry a unique code checkable on janoshik.com, the result can be independently verified.
The certificate
✅ Its certificate is its own. Thoroughbredlabs publishes its own Janoshik certificate of analysis, naming Thoroughbredlabs as the client, with its most recent certificate dated Sep 2025. Because Janoshik reports carry a unique code checkable on janoshik.com, the result can be independently verified.
What this certificate actually is: Its own Janoshik certificate, it names the seller as the client and can be verified on Janoshik's website.
⏳ This certificate is dated Oct 2025, 9 months old. A Certificate of Analysis only covers the single batch that was tested. Unless the seller has re-tested since, the stock you'd receive today is unverified, or it has sold the same batch for 9 months, which for a peptide is not credible.
Pricing vs the market, benchmarked on BPC-157
| BPC-157 | £3.4/mg (≈ £33.99 for a 10 mg vial) |
| Versus market median (£3.0/mg) | 1.1×, 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.
Google Ads
ℹ️ Note: this seller also runs Google ads for research peptides, a category Google's own policies prohibit, visible in Google's Ads Transparency Centre (UK). Worth knowing, but it doesn't bear on the question that puts it on the independently-tested list: its certificates are its own and genuine.
Payment
🚩 Bank only, 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 | 1.1× median (competitive) |
| Advertising in a banned category | Yes, live Google ads |
The bottom line. Thoroughbredlabs 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.
