Barrier Support: A Second, Separate Angle GHK-Cu's documented effect on glycosaminoglycan and collagen synthesis, covered in depth in our article on GHK-Cu: the copper peptide that started it all, is a mechanistically distinct pillar from the antioxidant one above, established mainly in wound-healing models
The lipotropic compounds in the injection help break down fat more efficiently, potentially aiding in weight loss efforts
For 5-amino-1MQ specifically: Preclinical studies have not prominently described heart rate elevation as a dominant signal The mechanism (NNMT inhibition, NAD+ preservation) does not have the same direct cardiac implications as nuclear receptor agonism Human cardiovascular data at clinically relevant exposures are limited For physicians, the current evidence base does not support a major cardiovascular safety flag, but the limited human dataset means confident statements are premature
For the fuller story on the peptide boom and what the evidence actually says, see my Economist feature: Want to hack your body with peptides
We'll break down availability, quality, and cost for each, and explain why most researchers end up buying online
