← Back to The GH Pulse Section 1: Compound Overview (Research Context Only) Hexarelin is a synthetic hexapeptide with the amino acid sequence His-D-2-MeTrp-Ala-Trp-D-Phe-Lys-NH2. The D-amino acid substitutions, mirror-image versions of standard amino acids found in natural proteins, give Hexarelin greater resistance to enzymatic degradation compared to many endogenous peptides. In preclinical and in vitro […]

← Back to The GH Pulse Compound Overview CJC-1295 is a synthetic peptide analog derived from the first 29 amino acids of endogenous growth hormone-releasing hormone, a hypothalamic signaling molecule that governs pituitary GH secretion. The native sequence, referred to as GHRH(1-29)NH2, retains the full biological activity of the complete 44-residue hormone but degrades rapidly […]

← Back to The GH Pulse Research Context Among the synthetic growth hormone secretagogues (GHSs) currently under investigation in preclinical and early-phase research, ipamorelin occupies a distinctive position owing to its reported receptor selectivity and relatively constrained off-target signaling profile. As a synthetic pentapeptide, ipamorelin was developed as an agonist at the growth hormone secretagogue […]

What Current Research Suggests About Sermorelin in GHRH Receptor Agonism

← Back to The GH Pulse Sermorelin occupies a specific and technically defined position in peptide research. It is a synthetic 29-amino acid fragment corresponding to the N-terminal sequence of endogenous growth hormone-releasing hormone, commonly designated GHRH(1-44). That truncation is the central fact around which most mechanistic questions about this compound are organized. Researchers working […]
