Dosing. DSIP is typically dosed at 100-300 mcg (before bed). GHK-Cu is typically dosed at 1-3 mg (daily).

Can you stack them?

Some protocols combine peptides, but stacking DSIP and GHK-Cu has not been validated for safety or efficacy in controlled trials. Combining compounds can change their effects and risks. Nothing here is medical advice — consult a qualified healthcare provider before starting or combining any protocol.
