Research Peptide Comparison
BPC-157 is a synthetic gastric pentadecapeptide with an established preclinical record across connective tissue repair, intestinal barrier restoration, and cytoprotective vascular signalling, acting through mechanisms largely independent of the hypothalamic–pituitary–gonadal (HPG) axis. Human Chorionic Gonadotropin (HCG) is a heterodimeric glycoprotein hormone — comprising α and β subunits — that binds to and activates the luteinising hormone/choriogonadotropin receptor (LHCGR), making it a well-characterised LH-mimetic tool compound for studying Leydig cell steroidogenesis, testosterone biosynthesis, and gonadal function in preclinical models. These two peptides occupy entirely separate positions within the research landscape: BPC-157 is studied for peripheral tissue-protective effects, while HCG is employed as a biochemical probe for HPG axis dynamics and reproductive endocrinology research.
BPC-157 (Body Protection Compound) is a synthetic pentadecapeptide derived from a protective protein found in human gastric juice. Investigated for its role in upregulating angiogenic pathways, modulating nitric oxide signalling and influencing growth-factor expression at sites of tissue injury, the sequence is widely cited across musculoskeletal, gastrointestinal and gut-brain axis studies.
Compared to HCG 5000iu, BPC-157 5mg is priced at £14.49 with 99%+ verified purity. Its CAS registry number is 137525-51-0. It has a molecular weight of 1419.53 g/mol.
BPC-157 5mg is available in 5mg, 10mg and ships with a full Certificate of Analysis from Janoshik Analytical. At £9.50 less than HCG 5000iu, it is the more affordable option in this comparison.
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 BPC-157 5mg, 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 £9.50 higher than BPC-157 5mg.
