Description
The practical rule: Unless a peptide has at minimum one of these modifications (cyclization, D-amino acid substitution, N-methylation, fatty acid conjugation, co-formulation with an absorption enhancer), assume oral bioavailability is negligible for any weight-loss pharmacological purpose

Vitamin C and copper peptides should generally not be applied in the same routine: the low pH of L-ascorbic acid can destabilise GHK-Cu, and the combination has been linked to increased irritation in some users
