Timing: Morning vs Evening Injections AM Dosing: May support fat loss and energy levels throughout the day
For hair loss specifically, this matters because GHK-Cu acts on the same biological pathways involved in follicle health: collagen synthesis, blood vessel formation, wound healing, stem cell signalling, and cell survival
Alternatively, the copper ion may contribute independently of the peptide, or the clinical effects may be mediated through surface-level signaling that does not require deep penetration
If you experience any electric shock sensations, numbness, or tingling during injection, stop immediately and reposition
Its safest to follow the 28-day rule
