How we read the certificate
Its certificate is its own. Lab77 Peptides publishes its own-name Janoshik certificates, thirty in all. The newest, analysed 27 October 2026 and naming Lab77peptides.uk as the client, are #244124 (retatrutide at 99.697%, 32.30 mg recovered, batch L77RETA27) and #244126 (tirzepatide at 99.863%, 43.13 mg recovered, batch L77Tirz27), each with an endotoxin test on the same batch (#244125 and #244127, both under 1 EU per vial), and #244123 (NAD+, 423.94 mg). Five more were analysed 23 October 2026: #244122 (BPC-157 at 99.976%, 11.68 mg recovered, batch L77BPC27), #244120 (GHK-Cu at 99.834%, 118.47 mg recovered, batch L77ghk27), #244128 (MOTS-c at 99.130%, 10.57 mg recovered, batch L77Mot27), #244121 (TB-500 at 98.602%, 10.07 mg recovered, batch L77TB27) and #244119 (a KLOW blend tested for identity and content only, batch L77Klow27). Before those, tests #231376 (tesamorelin at 98.241%), #231387 (CJC-1295 without DAC at 99.239%) and #237377 (ipamorelin at 99.654%) were analysed 29 September 2026. Seven more were analysed the day before, 28 September 2026: #231375 (Semax at 98.915%), #231378 (Selank at 99.981%), #231380 (KPV at 99.270%), #231381 (Epithalon at 98.829%), #231382 (Melanotan 2 at 99.390%), #231383 (DSIP at 99.443%) and #237376 (ARA-290 at 99.000%).

Earlier reports, among them #208427 (BPC-157 at 98.329%) and #208428 (TB-500 at 99.020%), analysed August 2026, name Lab77peptides.co.uk, the domain it traded under before moving, and all can be verified on Janoshik's website. It holds the most recent verified certificate in this index, so it sorts first in a list ranked by certificate date.

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 Lab77Peptides

Is Lab77Peptides legit?

On The Peptide Watch's independent audit, Lab77Peptides (lab77peptides.uk) publishes its own verifiable Janoshik certificate of analysis that names Lab77Peptides itself as the client, so its testing can be checked on Janoshik's own website. That is the strongest evidence standard we track. It confirms the credibility of the seller's evidence, not any individual vial you receive.

Does Lab77Peptides publish a real Certificate of Analysis?

Yes. Its most recent own-name Janoshik certificate is dated Oct 2026 and can be verified on Janoshik's website by its unique code, so the purity result cannot be faked or edited.

How do I check Lab77Peptides's certificate myself?

Find the certificate on lab77peptides.uk and read four things: an independent laboratory is named; the client field names Lab77Peptides, 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.

Are lab77peptides.com, lab77peptide.uk, lab77peptidesuk.co.uk, lab77peptide.uk and lab77peptide.co.uk the same shop?

  • lab77peptidesuk.co.uk is not this shop. It was registered on 29 September 2026. The Janoshik reports on its purity page are Lab77's own, made out to lab77peptides.uk, and its WhatsApp number and email address are not the ones Lab77 publishes. See our audit of lab77peptidesuk.co.uk →
  • lab77peptide.uk, without the "s", is not this shop's address. It was registered on 20 September 2026. On 12 October 2026 it showed a full WooCommerce shop trading as 'Lab77 Peptides UK'.
