Research-grade peptides.Zero compromises.
MyPeptides is a UK-based supplier of high-purity peptides, blends and injection pens for qualified researchers. Every batch is independently HPLC & MS verified and ships with a signed Certificate of Analysis — so your data starts with material you can trust.
Trusted material for real research.
MyPeptides was founded to fix a simple problem: researchers were paying premium prices for compounds shipped without documentation, without independent testing, and without a supplier accountable for what was actually inside the vial.
We built a supply chain from the opposite direction. We source lyophilised peptides from specialist manufacturers, send every batch to an independent UK laboratory, and only release product that meets our ≥99% purity target. Each order ships with the signed CoA for that exact batch.
Everything we sell is strictly for in-vitro laboratory research and analytical reference use. We do not make health claims and we do not sell to the general public.
Four things every batch has to earn.
Independently tested
Every batch analysed by a third-party UK lab. HPLC purity and mass spectrometry identity — no exceptions.
CoA in every box
Signed Certificate of Analysis with batch number, purity, method and date. Also emailed with your order.
Same-day UK dispatch
Order before 12:00 PM (Mon–Fri) and it ships the same working day, tracked to the UK and EU.
Shipment protected
If your parcel doesn't arrive, we resend or refund. Discreet, temperature-protected packaging.
