CJC-1295 vs Epitalon

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.

Epitalon

Epitalon (Epithalon) is a synthetic tetrapeptide based on the natural peptide epithalamin, produced by the pineal gland. It is primarily studied for its effects on telomerase activation.

Side-by-Side Comparison

Aspect	CJC-1295	Epitalon
Dose Range	1 mg–2 mg	5 mg–10 mg
Frequency	Less than daily	1x daily
Cycle Length	8–12 weeks	2–3 weeks
Route	subcutaneous	subcutaneous
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.	Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production 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.	Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year.
Administration	Subcutaneous injection, often combined with a GHRP like Ipamorelin for synergistic effects. Best administered before sleep or fasted.	Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously.
Side Effects	Water retention, tingling in extremities, potential increase in cortisol and prolactin levels.	Generally well-tolerated. May affect sleep patterns initially.
