CJC-1295 vs Epithalamin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
CJC-1295
CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to produce more growth hormone.
Full details →Epithalamin
Epithalamin is a natural peptide extract from the pineal gland. It is the precursor compound from which the synthetic Epitalon was derived. Known for anti-aging and telomerase-activating properties.

| Aspect | CJC-1295 | Epithalamin |
|---|---|---|
| Dose Range | 1 mg–2 mg | 5 mg–10 mg |
| Frequency | Less than daily | 1x daily |
| Cycle Length | 8–12 weeks | 1–2 weeks |
| Route | subcutaneous | intramuscular |
| Mechanism | CJC-1295 binds to GHRH receptors in the pituitary, triggering increased production and release of growth hormone. The DAC (Drug Affinity Complex) version extends half-life significantly. | Similar to Epitalon, it stimulates telomerase production and may help maintain telomere length. Also regulates melatonin synthesis and circadian rhythms. |
| Typical Dosage | CJC-1295 DAC: 1-2mg weekly. CJC-1295 no DAC (Mod GRF 1-29): 100-300mcg 2-3 times daily. | Research dosing: 10-20mg daily for 10-20 day cycles. Often administered 1-3 times per year in long-term protocols. |
| Administration | Subcutaneous injection, often combined with a GHRP like Ipamorelin for synergistic effects. Best administered before sleep or fasted. | Intramuscular or subcutaneous injection. Natural extract may have more variable composition than synthetic Epitalon. |
| Side Effects | Water retention, tingling in extremities, potential increase in cortisol and prolactin levels. | Generally well-tolerated. May affect sleep patterns. Less characterized than synthetic Epitalon. |
