Peptide Purity: We Publish The Data, Not Just The Price
Most research peptide suppliers list a purity figure and leave it there. A number on a product page is not analytical data.
Every batch we receive is tested and we publish the results. Each certificate includes the HPLC chromatogram showing the purity assessment, mass spectrometry confirming the molecular weight matches the expected value, the batch number, and the date of analysis. If a Certificate of Analysis (COA) on our site is more than six months old, we say so.
We want you to be able to check what you are buying before you buy it. That is the standard we work to, and it is the standard we think you should expect from any supplier.
How to Read a Certificate of Analysis →HPLC Purity Analysis
Chromatogram published for every batch, not a summary figure. Purity assessed by area percentage.
Mass Spectrometry
Molecular weight confirmation against the theoretical value, verifying compound identity.
Batch Traceability
Every vial carries a batch number that maps to a specific published certificate.

Are Research Peptides Legal in the UK?
Understand the regulatory position of research peptides in the United Kingdom and the conditions under which ThePeptideClub supplies these materials.
Research Peptides and UK Regulation
Research peptides are not licensed medicines in the United Kingdom. They hold no marketing authorisation from the MHRA, and under the Human Medicines Regulations 2012 it is unlawful to supply or market them for human use or with any medicinal claim.
Our Research Only Supply Position
We therefore supply these materials for one purpose only: in-vitro laboratory research. We do not provide dosing information, administration guidance, protocols, or any statement about effects in humans, and we will not respond to enquiries requesting them.
This is not a formality. It is the basis on which these materials can lawfully be supplied at all.
Looking for a Treatment or Supplement?
If you are looking for a treatment, a supplement, or a product to take yourself, this is not the right supplier for you. We encourage you to speak to a GP or a registered pharmacist instead.
Important: All products are supplied strictly for in-vitro laboratory research. They are not intended for human or veterinary consumption or administration.

Frequently Asked Questions
It means the material is supplied for in-vitro laboratory work only. These products are not licensed medicines, have not been assessed by the MHRA for safety or efficacy in humans, and must not be supplied or used for human consumption.
Yes. Each product page links to the certificate for the batch currently in stock, showing the HPLC chromatogram, mass spectrometry data, batch number and test date. All certificates are also in our COA archive.
All compounds are supplied at ≥98% by HPLC. The exact figure for each batch is on its certificate.
Compare the batch number on your vial label with the batch number and test date on the certificate. If they do not match, the report does not relate to your vial. Contact us with the product name and batch number.
We do not ask for a licence at checkout. You confirm that the purchase is for in-vitro laboratory research only and that you are 18 or over. These materials are not for human or veterinary use.
HPLC reports purity as the main peak’s share of the sample (area %). Mass spectrometry measures molecular mass and compares it with the theoretical mass. Neither alone confirms identity and purity, so read both with the batch number and test date.
As supplied, lyophilised and sealed, store at −20°C and protect from light. Stability data for each product is on its product page and in the Safety Data Sheet.
Unopened, undamaged vials can be returned within 14 days in their original packaging. We cannot accept opened vials or any product where the cold chain may have been broken. Full terms are in our Returns Policy.
No. We do not provide dosing, reconstitution, administration or protocol information, and we cannot answer questions about use in humans.
