Research Peptide Comparison
HCG and PT-141 are both peptide-based compounds studied for their interactions with receptor systems involved in hormonal and neuroendocrine signalling, yet they act on entirely separate receptor classes. HCG is a heterodimeric glycoprotein that binds the LHCGR receptor to stimulate testicular and ovarian steroidogenesis. PT-141, a synthetic cyclic heptapeptide, is a melanocortin receptor agonist selective for MC3R and MC4R engaging receptors within the central nervous system.
Human Chorionic Gonadotropin (hCG) is a placental glycoprotein hormone that binds the luteinising hormone (LH) receptor, driving downstream steroidogenic signalling in gonadal tissue. Its near-identical receptor affinity to endogenous LH makes it a standard probe in hypothalamic-pituitary-gonadal (HPG) axis investigation, reproductive endocrinology, and Leydig and theca cell stimulation studies.
Compared to PT-141 10mg, HCG 5000iu is priced at £23.99 with 99%+ verified purity. Its CAS registry number is 9002-61-3. It has a molecular weight of 36.7 kDa.
HCG 5000iu is available in single size and ships with a full Certificate of Analysis from Janoshik Analytical. It is priced £7.00 higher than PT-141 10mg.
PT-141 (Bremelanotide) is a cyclic heptapeptide melanocortin-receptor agonist with primary activity at the MC3R and MC4R subtypes, exerting its effects through central nervous system signalling rather than peripheral vascular pathways. This mechanism has placed it at the centre of research into central arousal circuits, sexual health pharmacology and melanocortin-system pharmacology more broadly.
Compared to HCG 5000iu, PT-141 10mg is priced at £16.99 with 99%+ verified purity. Its CAS registry number is 189691-06-3. It has a molecular weight of 1025.18 g/mol.
PT-141 10mg is available in single size and ships with a full Certificate of Analysis from Janoshik Analytical. At £7.00 less than HCG 5000iu, it is the more affordable option in this comparison.
