Key differences

Primary use. Epithalon is categorised under Sleep & Recovery, while Octreotide 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. Octreotide: FDA-approved.

Dosing. Epithalon is typically dosed at 5-10 mg (cycle protocol). Octreotide is typically dosed at 20–30 mg (LAR formulation, IM every 4 weeks); 100–600 mcg/day in divided doses (immediate-release SC) (Every 4 weeks (LAR); two to four times daily (immediate-release)).

Can you stack them?

Some protocols combine peptides, but stacking Epithalon and Octreotide 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.
