Research peptides

Documented quality for research and laboratory use. Every batch meets our internal purity standards.
Verified feedback from researchers across the UK & EU.
Shipping to mainland EU took 3 working days, tracked the whole way. Vials arrived intact, labels crisp, seals unbroken. Reordering next month.
Support answered a batch question within a few hours over email. Rare to get that level of response from a research supplier. Product itself is exactly to spec.
The little details matter - proper cold-chain, tamper-evident seals, and a CoA that actually reads like a lab report and not a marketing sheet.
Everything about this feels professional - from the site to the packaging to the paperwork. Purity assay matches what is on the label. Will keep ordering.
Site was easy to use, checkout was fast, and the product arrived exactly when they said it would. Straightforward, no drama, high quality.
Clean product, no discoloration, correct fill. Certificate of analysis was in the box AND emailed. Very straightforward experience.
FAQ
Everything you need to know about ordering, purity, dispatch and research use.
No. All MyPeptides compounds are sold strictly for in-vitro laboratory research and analytical reference use by qualified researchers. They are not medicines, supplements, cosmetics or food. Not for human or veterinary use.
Every batch is analysed by an independent UK laboratory. A Certificate of Analysis (CoA) documenting HPLC purity (≥99% target), mass spectrometry identity, appearance, and batch number ships in the box and is emailed with your order.
Orders placed before 12:00 PM UK time (Mon–Fri) dispatch the same working day from our UK facility. UK orders arrive next working day; mainland EU typically arrives within 2–4 working days, fully tracked.
Yes. We ship discreetly across the UK and mainland EU with tracked, temperature-protected packaging. Shipping is free on qualifying orders and every shipment is protected — if it does not arrive, we resend or refund.
Lyophilised peptide vials are shipped at ambient temperature and should be refrigerated (2–8°C) on arrival. After reconstitution with bacteriostatic water, refrigerate and use within the timeframe documented on the CoA for that compound.
We accept all major credit and debit cards, plus Apple Pay, Google Pay and bank transfer at checkout. All payments are processed through PCI-compliant providers; MyPeptides does not store card details.
