CJC-1295 vs Epitalon
Overview
CJC-1295 is primarily a performance & growth peptide, while Epitalon is used for anti-aging & longevity.
This page compares CJC-1295 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
| CJC-1295 | Epitalon | |
|---|---|---|
| Category | Performance & Growth | Anti-aging & Longevity |
| Regulatory status (US) | Research use only | Compounding (Rx) — Apr 2026 |
| Typical dosage | 1-2 mg | 5-10 mg |
| Frequency | weekly | cycle |
| Reported benefits | Increased muscle mass, fat loss, improved recovery, better sleep, enhanced bone density | 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 | Water retention, joint pain, potential insulin resistance with prolonged use | 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. CJC-1295 is categorised under Performance & Growth, 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. CJC-1295: not FDA-approved; treated as a research compound. Epitalon: not FDA-approved; compounding permitted with a prescription as of April 2026.
Dosing. CJC-1295 is typically dosed at 1-2 mg (weekly). Epitalon is typically dosed at 5-10 mg (cycle).
Can you stack them?
Some protocols combine peptides, but stacking CJC-1295 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.
