Peptides are grouped by the receptor family they engage or by their historical research context. The main groups relevant to the Peptide Life catalog are outlined below.
Incretin (GLP-1, GIP)
Semaglutide, Tirzepatide and Retatrutide are studied for their activity on GLP-1R and, in dual/triple agonists, on GIPR and GCGR. They are central to metabolic research.
Regenerative
BPC-157 and TB-500 are investigated in preclinical models of angiogenesis, actin dynamics and tissue signaling.
GH secretagogues and GHRH analogs
Ipamorelin, CJC-1295, Tesamorelin and Sermorelin are used to study the GHS-R1a and GHRH-R axes and their downstream effects on IGF-1 and lipid metabolism.
Neuropeptides
Selank and Semax are researched in neurobiological models of GABAergic and BDNF-related signaling.
Dermatological
GHK-Cu and AHK-Cu are copper-binding peptides studied in extracellular matrix and follicular signaling models.
