Choosing a research peptide supplier in the UK
Three things separate suppliers, and none of them is price. Whether a certificate exists for the exact batch you receive, not a representative one from months ago. Whether that certificate came from a laboratory with no stake in the result. And whether the supplier will tell you what the certificate means. Our guide to HPLC and LC-MS explains what the two headline figures measure, and the quality page sets out the rule we work to: nothing is listed until its certificate is public.
The compound library has a monograph on every compound here, covering structure, what the published research describes, UK status and handling. The comparison guides, such as BPC-157 vs TB-500 and semaglutide vs tirzepatide, are for deciding between two compounds that are often mentioned together.
Questions
Is it legal to buy research peptides in the UK?
Yes, as chemicals for in-vitro laboratory research. They are not medicines, are not sold for human or veterinary use, and buyers must be 18 or over. The law is set out in our guide. Research peptides and UK law.
What does batch-certified mean here?
Every lot is tested by an independent laboratory for purity by HPLC and identity by LC-MS before it goes on sale, and the certificate is published on the product page and in the register. No certificate, no listing. Certificate register.
How do I read a certificate of analysis?
Purity is the main HPLC peak as a share of all peaks; identity is the measured mass against the theoretical one. The guide goes line by line, including the signs of a certificate not worth trusting. Reading a certificate of analysis.
How quickly is an order dispatched?
Orders paid before 3pm Monday to Saturday leave the same day by Royal Mail Tracked 24, in plain packaging, with a tracking number emailed when the label is printed. Delivery.
How should peptides be stored?
Sealed vials at 2–8 °C for routine use and −20 °C for longer storage, away from light. Reconstituted solutions depend on the peptide; the storage guide covers each class. Storage and stability.
