Metabolic Peptides.

The incretin family, as a ladder: GLP-1 engages one receptor, GLP-2T pairs it with GIP, and GLP-3R adds glucagon for a triple profile. Together they cover the designs modern metabolic research actually runs — receptor-activation assays, appetite and glucose models, and head-to-head comparisons of how much each added receptor contributes.

Every vial is verified batch-by-batch by an independent US lab — purity by HPLC, identity against the CAS record, endotoxins under 0.5 EU/mg — with the certificate of analysis included with every order.
