Two of the more distinctive research peptides in any catalog, semax and selank, share an origin that sets them apart from nearly everything else on the shelf: they come out of a Russian body of neuropeptide research that is large,…

Line up the metabolic research peptides in most catalogs and a pattern emerges: semaglutide, tirzepatide, retatrutide. They form a clear progression, each engaging more incretin receptors than the last. Then there is cagrilintide, which does not fit the pattern at…

Search any research peptide catalog and a large share of the growth-hormone-related compounds fall into a family that confuses newcomers because the names give no hint of how they relate. Sermorelin, tesamorelin, CJC-1295, ipamorelin, GHRP-6, and others all touch the…

Few research peptides generate as much naming confusion as CJC-1295, and nearly all of it traces to three letters: DAC. Shoppers see “CJC-1295 with DAC” and “CJC-1295 no DAC” listed as separate products and reasonably wonder whether they are the…

Nearly every peptide in a research catalog ships as a lyophilized powder, and nearly every protocol that uses one begins the same way: dissolving that powder in a diluent. The diluent chosen most often is bacteriostatic water. This guide explains…
