BPC-157 is a synthetic pentadecapeptide derived from a protective gastric protein. Decades of preclinical research have examined its effects on connective tissue, the nervous system, and gastrointestinal function.
TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring 43-amino acid peptide involved in actin sequestration, cell migration, and tissue repair processes.
Ipamorelin is a pentapeptide growth hormone secretagogue notable for its selective stimulation of GH release without significant co-stimulation of cortisol, prolactin, or ACTH — a profile that distinguishes it from earlier GHRPs.
CJC-1295 is a synthetic analogue of growth hormone-releasing hormone (GHRH) engineered for extended half-life. The DAC (Drug Affinity Complex) variant achieves albumin binding that dramatically prolongs its activity compared to native GHRH.
