A common approach uses 4-8 weeks on followed by 2-4 weeks off
Technically, yes for a short period
Some research protocols call for storing GHK-Cu under inert gas (nitrogen or argon), though this is more commonly required for long-term stock solutions than for lyophilized powder
The clinician can also help determine whether standard care, physical therapy, imaging, nutrition, sleep optimization, hormone evaluation, or another treatment should come first
Repeated freeze-thaw cycles can degrade any peptide, including GHK-Cu, by causing structural stress
If current trends continue, this copper peptide could play a major role in dermatology
