Research Peptide Comparison
Ipamorelin and Kisspeptin occupy distinct but complementary positions within endocrine signalling research. Ipamorelin is a selective growth hormone secretagogue that acts on ghrelin receptors (GHSR-1a) to stimulate pulsatile GH release from the anterior pituitary, without significantly perturbing cortisol or prolactin levels. Kisspeptin, encoded by the KISS1 gene and acting via the GPR54 (KISS1R) receptor, functions as a master upstream regulator of the hypothalamic-pituitary-gonadal (HPG) axis, controlling GnRH neuron activation and thereby governing the reproductive endocrine cascade.
Ipamorelin is a pentapeptide growth hormone-releasing peptide (GHRP) and selective agonist of the ghrelin (GHS-R1a) receptor. It is widely cited for its capacity to stimulate pituitary GH release without the cortisol, prolactin or aldosterone elevations associated with earlier GHRPs, making it a clean reference ligand in somatotropic and receptor-selectivity research.
Compared to Kisspeptin 5mg, Ipamorelin 5mg is priced at £19.99 with 99%+ verified purity. Its CAS registry number is 170851-70-4. It has a molecular weight of 711.85 g/mol.
Ipamorelin 5mg is available in 5mg, 10mg and ships with a full Certificate of Analysis from Janoshik Analytical. It is priced £1.00 higher than Kisspeptin 5mg.
Kisspeptin-10, the C-terminal decapeptide fragment of metastin, is the minimal active sequence at the KISS1R (GPR54) receptor and a primary upstream regulator of GnRH neuron firing. By controlling pulsatile GnRH release, it sits at the apex of the hypothalamic-pituitary-gonadal (HPG) axis and has become a central tool in fertility, puberty-onset and reproductive endocrinology investigation.
Compared to Ipamorelin 5mg, Kisspeptin 5mg is priced at £18.99 with 99%+ verified purity. Its CAS registry number is 374675-21-5. It has a molecular weight of 1302.48 g/mol.
Kisspeptin 5mg is available in 5mg, 10mg and ships with a full Certificate of Analysis from Janoshik Analytical. At £1.00 less than Ipamorelin 5mg, it is the more affordable option in this comparison.
