Dosing. Groprinosin is typically dosed at 500-1000 mg (three times daily). KPV is typically dosed at 500-1000 mcg (daily).
Can you stack them?
Some protocols combine peptides, but stacking Groprinosin and KPV 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.
