GHRP-6 is the amidated hexapeptide His-D-Trp-Ala-Trp-D-Phe-Lys-NH2. Its D residues, terminal amide, counterion and content basis are identity-critical.
Evidence at a glance
- The catalog record uses formula C46H56N12O6 and molecular weight 873.01 g/mol for the free peptide.
- His-D-Trp-Ala-Trp-D-Phe-Lys-NH2 differs from GHRP-2 and Hexarelin despite sharing class-level pharmacology.
- Chromatographic area percent and biological response answer different quality questions.
Identity record
A six-letter one-letter sequence would not record the D configuration at Trp2 and Phe5. Identity documentation must preserve stereochemistry and terminal chemistry rather than relying on the class name.
Analytical and evidence boundary
Acetate and water can materially change the relationship between total weighed material and peptide-equivalent amount. A certificate should state the reported basis and test methods.
Detection in an anti-doping workflow or GH release in volunteers does not demonstrate purity, potency, sterility or stability of an unrelated lot.
Editorial rule
State the exact material, form, model or population and endpoint supported by the cited record. Do not convert mechanistic plausibility, an animal result, an official finished-drug label or an analytical test into a claim about an unrelated catalog lot.
