CJC-1295 vs Oxytocin

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.

Oxytocin

Oxytocin is a natural hormone produced in the hypothalamus, often called the 'love hormone' or 'bonding hormone.' It plays key roles in social bonding, childbirth, lactation, and stress regulation.

Side-by-Side Comparison

Aspect	CJC-1295	Oxytocin
Dose Range	1 mg–2 mg	24 mcg–48 mcg
Frequency	Less than daily	1x daily
Cycle Length	8–12 weeks	2–4 weeks
Route	subcutaneous	intranasal
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.	Binds to oxytocin receptors in the brain and peripheral tissues. Promotes social bonding, reduces anxiety and stress response, and has various peripheral effects on smooth muscle contraction.
Typical Dosage	CJC-1295 DAC: 1-2mg weekly. CJC-1295 no DAC (Mod GRF 1-29): 100-300mcg 2-3 times daily.	Intranasal: 20-40 IU (international units) for social/anxiolytic effects. Clinical uses (labor induction) require IV administration under medical supervision.
Administration	Subcutaneous injection, often combined with a GHRP like Ipamorelin for synergistic effects. Best administered before sleep or fasted.	Intranasal spray for behavioral effects. IV only in clinical settings. Sublingual also possible. Best used situationally rather than continuously.
Side Effects	Water retention, tingling in extremities, potential increase in cortisol and prolactin levels.	Intranasal: headache, nasal irritation, drowsiness. May cause over-attachment or emotional sensitivity. IV (clinical): uterine hyperstimulation, water retention.
