Our peptides are produced by specialist manufacturing partners and independently analysed by accredited third-party labs. We are moving our testing to Vanguard Laboratory in Olympia, Washington (A2LA-accredited, ISO 17025), with reports issued to Peptigo in our own name: batch-level testing, done in the USA. Products tested earlier carry manufacturer-lot reports from Janoshik Analytical, each of which opens on Janoshik’s own verification page; those stay here until each product’s Vanguard report is in.
We’re upfront about it: the reports below are issued to our manufacturing partners, not commissioned by us — and you can verify each one directly with the lab.
Our compounds are synthesised by established peptide manufacturers who submit samples for independent analysis.
Manufacturer lots were analysed by Janoshik Analytical (identity by mass-spectrometry, purity by HPLC). Our own batch testing now goes to Vanguard Laboratory in the USA, an A2LA-accredited, ISO 17025 lab. We don’t run these in-house — no conflict of interest.
Janoshik reports open on the lab’s own verification portal: the original record, not a copy we host. Vanguard reports are published here as the signed PDF, with the laboratory ID you can quote to the lab.
Two products carry a Vanguard report commissioned by Peptigo, and 15 carry a manufacturer-lot Janoshik report. The rest are being tested at Vanguard and added as they come in.
These products are in the queue for third-party analysis. We add each report the moment it’s verified — we’d rather show nothing than show something we can’t back up.
