What we found
SPT Peptide checked 10 September 2026. Every one of SPT Peptide's 46 certificates credits 'Brown Biology Laboratory'. The reports name SPTPEPTIDE as the client and say they are searchable at brown-biology-laboratory.com, but that domain was registered on 9 June 2026, and reports on the site carry earlier dates: TB-500 (report #20265185) says it was reported on 9 May 2026 and AOD9604 (#20265108) on 27 May 2026. The lab's own site describes a US contract research organisation with 240 experts and ISO 17025 accreditation, while its services page says 'ISO 17025 in Progress'; the reports give a free webmail address as the lab's contact, and the lab's public lookup index holds 91 reports in total. On SPT's own certificates page, six records list a best-before date earlier than the manufacture date (AOD9604, Ipamorelin, Lemon Bottle, Pinealon, Selank, SNAP-8), and one research-passport number, 2026517, is shared by five different products. None of this proves the results are wrong, but none of it can be checked independently. Until SPT publishes a report from a recognisable independent lab such as Janoshik, naming SPT Peptide as the client, it stays on the watch list.
New Since 13 October 2026 you can tell us how your order went. Reports go up on this page from 1 November 2026, bad ones as well as good, because UK law doesn't let review sites hide negative reviews. A written note appears only after we have read it.

The certificate, and what's wrong with it

How buyer reports work
- Every report is confirmed by email before it counts, and each email address can report on a seller once every 90 days.
- We hold back anything that looks like a seller reviewing itself: an email from the seller's own domain, several reports from the same connection, or a sudden burst in a day. A person checks those before anything shows.
- Tick-box answers are shown only as totals. A written comment appears after a person has read it, exactly as the buyer wrote it: we don't edit comments or hold them back, good or bad, and UK consumer law (the Digital Markets, Competition and Consumers Act 2024) doesn't let review sites hide negative reviews. The only thing we take out is personal details, such as a name, phone number or email address.
- Sellers can reply. If a seller disagrees with what buyers report, it can email [email protected] from its own domain, and we show one response next to the totals, with the date.
- No single thing on this page should decide it. Look at the lab reports, the buyer reports and how you'd pay, together.
Questions people ask about SPT Peptide
Is SPT Peptide legit?
SPT Peptide (sptpeptide.com) 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.
Does SPT Peptide publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ Its certificates come from a lab we cannot confirm independently. SPT Peptide sells research peptides in GBP from a UK storefront, operated by SPT Peptide Ltd (Companies House 17328366, incorporated 8 July 2026, registered in Hoxton, London, active).
How do I check SPT Peptide's certificate myself?
Find the certificate on sptpeptide.com and read four things: an independent laboratory is named; the client field names SPT Peptide, not a supplier; the compound line names the peptide you are buying, not only a batch code; and the report opens on the laboratory's own website from its task number and key (verify.janoshik.com for Janoshik). Then compare the batch number on the report with the one on your vial. The free COA Checker on this site runs the first three checks on a photo of the certificate.
