Research compound catalogue

High-performance liquid chromatography (HPLC) separates a sample by its molecular constituents so the proportion of target peptide versus impurities can be measured. A ≥99% reading means the named peptide accounts for at least 99% of the peptide content in that batch. Every Velox batch is tested by an independent third-party laboratory and the result is recorded on a batch-specific certificate of analysis, with mass-spectrometry confirmation of identity. You can read the full method on our quality and testing page and view live certificates in the CoA library.

The catalogue is grouped into five research areas so you can browse by mechanism of interest: cognitive (e.g. Semax, Selank), metabolic (e.g. Retatrutide, Tesamorelin, MOTS-c), recovery (e.g. BPC-157, TB-500), growth (e.g. CJC-1295, Ipamorelin) and antioxidant (e.g. GHK-Cu, Glutathione, NAD+). Each compound page summarises the published research and receptor pharmacology, and our research guides and comparison tool let you weigh compounds side by side before selecting.

No. Every product is supplied strictly as a research reagent for in vitro laboratory use by qualified researchers. None are licensed medicines, and nothing is supplied for human or veterinary administration. Full terms are set out in our Research Use Policy and MHRA statement.

Compounds ship as lyophilised (freeze-dried) powder, which is stable for extended periods when kept cold and dark. For laboratory preparation, the powder is typically reconstituted with bacteriostatic water; once reconstituted it should be refrigerated and used within its stability window. Our reconstitution calculator works out the exact water volume and resulting concentration for any vial size.

Yes. Every order includes the batch-specific certificate of analysis covering HPLC purity, mass-spectrometry identity confirmation and appearance. Certificates are emailed with your order confirmation and published in the public CoA library so any batch can be verified before or after purchase.
