What is Pepmarket?
Pepmarket is a UK directory of research-peptide suppliers. We catalogue suppliers and peptides so researchers can find reputable sources quickly. We never sell or ship products ourselves.
Are the suppliers vetted?
We track publicly verifiable signals for every supplier (site verification, third-party lab testing and shipping policies) and mark partnered suppliers that have completed our onboarding checks.
Is Pepmarket free to use?
Yes. Browsing the directory and using the calculators is completely free. When suppliers partner with us we may earn a referral commission. Featured listings are promoted placements: they are shown first and always marked Featured. Nothing else a supplier pays for changes how it is listed or ranked.
Are peptides legal in the UK?
Most research peptides can be sold legally in the UK for laboratory research use only. They are not licensed medicines and nothing on this site is medical advice.
How do I reconstitute a peptide?
Lyophilised peptides are reconstituted with bacteriostatic water. Our free calculator works out the concentration and syringe units for any vial size, water volume and target dose.
