It also means the dosing window is more flexible than peptides that require precise timing around growth hormone release patterns

To minimize environmental exposure, containers should remain tightly sealed when not in use and handled according to established laboratory protocols

During the loading phase , patients typically receive 1mg of hydroxocobalamin intramuscularly three times per week for two weeks (six injections total)

This may be due to copper's ability to enhance the expression of metalloproteinases (MMPs).16 MMPs normally regulate the degradation of collagen, and a specific one, MMP-1, may be responsible for the initiation of collagen fragmentation.17 Supporting this, a 2024 study noted that elevated MMP-1 levels appear to contribute to aging skin and that higher MMP-1 levels in mice led to:18 The loss and fragmentation of dermal collagen fibrils Contracted fibroblast morphology Reduced collagen production Increased expression of pro-inflammatory mediators Additionally, a 2016 study found that GHK-Cu significantly increased gene expression of MMP-1 and MMP-2 at the lowest concentration, which the studys authors considered to be one of the reasons the peptide was able to increase collagen and elastin production.19 So, what this could ultimately mean is that using too much GHK-Cu (or other copper peptides) may in theory increase the skins MMP-1 concentration above the levels involved in healthy collagen production, taking it into the collagen fragmentation and breakdown territory seen in older skin with naturally higher MMP-1 levels
