Dosing. DSIP is typically dosed at 100-300 mcg (daily). Epithalon is typically dosed at 5-10 mg (cycle protocol).

Can you stack them?

Some protocols combine peptides, but stacking DSIP and Epithalon 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.
