Those following vegetarian or vegan diets, individuals with absorption issues such as Crohns or celiac disease, people taking certain medications, or older adults may be at greater risk of deficiency

Key features include: 99% purity, confirmed by HPLC and mass spectrometry for analytical accuracy and research reproducibility Pentapeptide structurewith non-proteinogenic residues (Aib and D-amino acids) conferring exceptional metabolic stability and resistance to non-specific proteolytic degradation High receptor selectivitydemonstrating minimal activity on non-target pituitary hormones including ACTH, cortisol, prolactin, FSH, LH, and TSHdistinguishing it from less selective growth hormone secretagogues Potent GHS-R1a agonist activitywith ED = 2.3 nmol/kg in conscious animal models, comparable to GHRP-6 efficacy but with enhanced selectivity Lyophilized powder formatproviding extended shelf-life stability of up to 24 months when stored appropriately, with minimal degradation under recommended cold-storage conditions Widely utilized as a pharmacological tool compoundfor structure-activity relationship (SAR) investigations and receptor-ligand selectivity studies For laboratory research use only These properties support its use as ipamorelin for research across receptor pharmacology, endocrine signaling, and growth hormone axis investigations
