Key differences

Primary use. Epithalon is categorised under Sleep & Recovery, while Pasireotide falls under Hormonal. Their differing categories mean they are usually chosen for different goals rather than as direct substitutes.

Regulatory status. Epithalon: not FDA-approved; compounding permitted with a prescription as of April 2026. Pasireotide: FDA-approved.

Dosing. Epithalon is typically dosed at 5-10 mg (cycle protocol). Pasireotide is typically dosed at 0.6–0.9 mg SC twice daily (Cushing's disease, SC formulation) or 40–60 mg IM every 4 weeks (acromegaly, LAR); 10–40 mg IM every 4 weeks (Cushing's disease, LAR) (Twice daily (SC formulation) or every 4 weeks (LAR formulation)).

Can you stack them?

Some protocols combine peptides, but stacking Epithalon and Pasireotide 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.
