Finding a UK research peptide supplier
Who is Owsa Labs?
Owsa Labs is a UK supplier of lyophilised research peptides for laboratory use only. We publish batch-linked third-party certificates of analysis when we have them, ship UK-only with free delivery, and offer educational tools (Atlas evidence grades and a reconstitution calculator). Not a pharmacy. Not for human consumption.
Where can I buy research peptides in the UK?
Owsa Labs supplies research-use lyophilised peptides to UK addresses only (including Northern Ireland). Checkout blocks non-UK destinations. See the shop, certificates of analysis, and shipping pages. Match any COA to the lot on the vial.
What should I look for in a research peptide supplier?
Prefer clear research-use-only framing (no human-use advice), UK dispatch, transparent shipping, batch-specific third-party COAs you can verify, honest unpublished gaps, and storage/handling guidance. Owsa Labs publishes COA coverage as a count on the certificates page and links verifiable reports where available.
Do you ship internationally?
Owsa Labs primarily ships within the United Kingdom. Checkout is set up for UK addresses.
If you are outside the UK and want to enquire about delivery, email support@owsa-labs.com before ordering. We do not offer open international checkout. Any export we agree is arranged case by case after we speak with you.
Important:
- Products are for laboratory / research use only — not for human or veterinary use.
- You are responsible for checking whether you may legally import these materials into your destination.
- If a parcel is delayed, inspected, returned, or seized by customs or any local authority, that risk sits with you. We cannot guarantee clearance and do not treat seizure as a reason to automatically reship or refund.
- Duties, taxes, and brokerage fees (if charged) are your responsibility unless we explicitly agree otherwise in writing.
Include your country, products/quantities of interest, and delivery city/postcode when you email support@owsa-labs.com.
Do you accept cards?
Yes. You can pay for research peptides by card at checkout with Visa or Mastercard, and with Apple Pay or Google Pay where your device supports them. A card processor fee is added when you pay by card or wallet — it is shown before you confirm. Pay by Bank (Wallid) and crypto are also available and do not use that card fee. Full detail: Payment methods.
Do you accept Apple Pay / Google Pay?
Yes. Apple Pay and Google Pay are available at checkout alongside Visa and Mastercard, where your phone, tablet, or browser supports them. The same card processor fee that applies to card payments is added for wallet checkout. See Payment methods.
Products and documentation
Do you provide a certificate of analysis?
Where a third-party report exists for the lot you receive, it is linked from the product page and listed on the certificates page. Where one does not, the catalogue says so plainly. We currently publish reports for 21 of 70 catalogue lines. Match any report to the lot on your vial.
Legal position and use
Can you tell me what quantity to use?
No. We do not give guidance on human use in any form.
