All content is provided for scientific reference and educational purposes only.Ipamorelin (Aib-His-D-2-Nal-D-Phe-Lys-NH₂) is a highly selective pentapeptide GHS-R1a agonist — notable for its exceptional selectivity profile, driving GH secretion without significant co-stimulation of cortisol, prolactin, or ACTH. This selectivity is particularly valuable in neurological…

All content is provided for scientific reference and educational purposes only.Sermorelin (GHRH 1-29 NH₂) is a synthetic analogue of endogenous growth hormone-releasing hormone (GHRH), consisting of the first 29 amino acids of the 44-amino acid GHRH sequence. As a GHRHR agonist, Sermorelin drives pulsatile…
