Lyophilised research peptides, each tested by an outside laboratory with the full certificate published rather than summarised. The catalogue runs from short unmodified sequences through to receptor-selective analogues and multi-receptor agonists.Peptides in this category differ in more than their target. Some are short and unmodified and dissolve in bacteriostatic water without argument; others are cyclic, carry a disulfide bridge, or hold a metal centre, and each of those features changes how the vial should be handled. Our research library covers the handling that applies to all of them, and the pharmacology that applies to particular ones.Every product page below carries the compound background, reconstitution notes and the certificate. All products are sold for laboratory research use only.
