DSIP vs Epitalon
Overview
DSIP is primarily a sleep & recovery peptide, while Epitalon is used for anti-aging & longevity.
This page compares DSIP and Epitalon across their primary use, typical dosing, reported benefits and side effects, and U.S. regulatory status. For the full monograph on either compound — mechanism of action, clinical research, and references — follow the article links.
Side-by-side comparison
| DSIP | Epitalon | |
|---|---|---|
| Category | Sleep & Recovery | Anti-aging & Longevity |
| Regulatory status (US) | Compounding (Rx) — Apr 2026 | Compounding (Rx) — Apr 2026 |
| Typical dosage | 100-300 mcg | 5-10 mg |
| Frequency | before bed | cycle |
| Reported benefits | Improved deep sleep, stress reduction, recovery enhancement, pain reduction | Areas studied (research-reported, not established efficacy): telomerase activation and telomere elongation in human cell lines (PMID 12937682; DOI 10.1007/s10522-025-10315-x); increased melatonin synthesis and circadian effects in a small human study; lower overall and cardiovascular mortality in a 12-15 year single-lab trial that used pineal extract (epithalamin), not synthetic AEDG (PMID 17426848, 22451889). No independent multi-center RCTs; not FDA-approved. |
| Reported side effects | Very well-tolerated, possible grogginess | Khavinson-group trials reported no serious adverse events (e.g., n=162 retinitis pigmentosa trial, PMID 12195242), but these are the only controlled safety data and remain unreplicated. Community use reports mild injection-site reactions. Theoretical concern: telomerase activation is a hallmark of most cancers, and a 2025 review (PMC11943447) notes carcinogenic potential is unstudied. No human pharmacokinetic or drug-interaction data. |
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.
