HPLC & Mass Spectrometry Verified Batch-Specific Certificate of Analysis (CoA) Included Sterile Lyophilised Powder | GMP Manufactured Fast Dispatch to Ireland | Peptides Ireland Stock Melanotan 1 and Afamelanotide , is a synthetic tridecapeptide with the sequence Ac-Ser-Tyr-Ser-Nle-Glu-His-D-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2, representing a stabilised analogue of the endogenous tridecapeptide -melanocyte-stimulating hormone (-MSH) in which methionine at position 4 is replaced by norleucine (Nle4) to prevent oxidative inactivation, and phenylalanine at position 7 is replaced by D-phenylalanine (D-Phe7) to confer resistance to endopeptidase cleavage and stabilise the pharmacophore conformation required for high-affinity MC1R binding
Safety Considerations for Injured Individuals While peptides like BPC 157 and TB 500 appear promising, they are not without risks: Side effects reported include nausea, headaches, dizziness, and injection-site reactions
This effect is particularly notable in older adults, women, and those with lower protein intake
