Research Comparison
GHRP-2 vs Tesamorelin
A side-by-side research comparison of GHRP-2 and Tesamorelin drawn from Cobalt Peptides' peptide database records.
GHRP-2
GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide belonging to the growth hormone secretagogue (GHS) class. It stimulates the release of endogenous growth hormone (GH) primarily through activation of the ghrelin receptor (GHS-R1a) in the hypothalamus and pituitary. Unlike GHRH analogs, GHRP-2 acts via a distinct pathway, making it highly synergistic when combined with GHRH-based peptides. It is widely used in research to investigate growth hormone pulsatility, appetite signalling, and metabolic regulation.
Tesamorelin
Tesamorelin is a synthetic analogue of growth hormone-releasing hormone (GHRH), a 44-amino acid peptide carrying a trans-3-hexenoic acid modification at the N-terminus that confers resistance to enzymatic degradation. It binds the GHRH receptor, and the published literature describes pulsatile growth hormone release and downstream IGF-1 elevation. A licensed medicine containing tesamorelin exists in some jurisdictions and is prescribed by clinicians; the material supplied here is a research compound and is not that medicine.
