Doctors swear an oath to first, do no harm, and are expected to use treatments supported by evidence or, at minimum, a plausible expectation of benefit outweighing risks
Understanding these differences helps researchers set realistic expectations and develop management strategies before problems arise
Cysteine is a rate-limiting precursor substrate for GSH synthesis, and its level is regulated by SLC7A11 encoding the cystine/glutamate transporter XCT, which is primarily responsible for the export of glutamine in exchange for extracellular cystine [9]

PubMed ID: 10204116 GHRP-2 vs Other GHS-R1a Research Peptides Feature GHRP-2 GHRP-6 Ipamorelin Hexarelin Sequence D-Ala-D-Nal-Ala-Trp-D-Phe-Lys-NH (6aa) His-D-Trp-Ala-Trp-D-Phe-Lys-NH (6aa) Aib-His-D-2-Nal-D-Phe-Lys-NH (5aa) His-D-2-MeTrp-Ala-Trp-D-Phe-Lys-NH (6aa) GHS-R1a Activity More potent than GHRP-6 Potent (founding reference) Potent (most selective) Most potent classic GHRP CD36 Binding Yes (confirmed) Yes (confirmed) Not established Yes (confirmed) ACTH/Cortisol Release Yes (significant) Yes (significant) No (selective GH only) Yes (significant) GHRH Co-Dependency Partial Yes (82% of GH response) Partial Partial GI Motility Research Limited Yes (motilin receptor interaction) Not established Limited Cardioprotection Research Moderate Extensive None Extensive Wound Healing Research None established Published (PPAR/TGF-) None None CD36 Drug Discovery Secondary scaffold Primary scaffold None Secondary Historical Significance High-potency second-generation GHRP Discovery peptide (led to ghrelin) First selective GHRP Most potent classic GHRP GHRP-2s combination of enhanced GHS-R1a potency relative to GHRP-6, confirmed CD36 pharmacology, significant HPA axis co-stimulation, and role as a second-generation comparative reference compound makes it an essential research tool for GH axis biology, pituitary pharmacology, and cytoprotective pathway research occupying a distinct niche from the selective Ipamorelin (no HPA co-stimulation, no CD36), the more extensively CD36-characterised GHRP-6 (lower GHS-R1a potency), and the extremely potent Hexarelin (more restricted research application)

WADA continues to implement regulatory updates, athlete education resources, Therapeutic Use Exemption programs, and whereabouts monitoring to preserve the integrity of athletics
