While these effects are helpful for weight loss, they can also contribute to constipation
However, in line with the specificity of CPA, the C-terminal residues of the L585I, L585M, and L585V variants were cleaved in vitro upon exposure to the enzyme for 5 hours at 37 C, as confirmed by liquid chromatography with tandem mass spectrometry (LC-MS/MS) analysis of the C-terminal peptides (Supplementary Table 1)
These numbers highlight the central honest caveat: GHK-Cu has mechanistic plausibility and early clinical signals, but the gap between those signals and the established human trial record for retinoids is significant
