Key differences
Primary use. DSIP is categorised under Sleep & Recovery, while Epitalon falls under Anti-aging & Longevity. Their differing categories mean they are usually chosen for different goals rather than as direct substitutes.
Regulatory status. DSIP: not FDA-approved; compounding permitted with a prescription as of April 2026. Epitalon: not FDA-approved; compounding permitted with a prescription as of April 2026.
Dosing. DSIP is typically dosed at 100-300 mcg (before bed). Epitalon is typically dosed at 5-10 mg (cycle).
Can you stack them?
Some protocols combine peptides, but stacking DSIP and Epitalon 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.
