does ghk cu mess with hormones GHK-Cu for Anti-Aging: This Copper Peptide Really Work? The Risks of Using GHK-Cu

Furthermore, sourcing introduces uncertainty in sterility and formulation integrity, which may represent a more immediate and clinically relevant risk than theoretical biologic effects, particularly given the potential for nonsterile preparation, contamination, or inconsistent formulation in nonregulated injectable products

The recognition sequence of amino acids also plays a significant role in the use of peptides

While the peptide appeared well tolerated in these trials, the absence of reproducible clinical benefit meant the molecule did not progress to approval or further late-stage studies
