Oxytocin vs CJC-1295
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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.
Full details →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 →Side-by-Side Comparison
| Aspect | Oxytocin | CJC-1295 |
|---|---|---|
| Mechanism | 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. | 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. |
| Typical Dosage | Intranasal: 20-40 IU (international units) for social/anxiolytic effects. Clinical uses (labor induction) require IV administration under medical supervision. | CJC-1295 DAC: 1-2mg weekly. CJC-1295 no DAC (Mod GRF 1-29): 100-300mcg 2-3 times daily. |
| Administration | Intranasal spray for behavioral effects. IV only in clinical settings. Sublingual also possible. Best used situationally rather than continuously. | Subcutaneous injection, often combined with a GHRP like Ipamorelin for synergistic effects. Best administered before sleep or fasted. |
| Side Effects | Intranasal: headache, nasal irritation, drowsiness. May cause over-attachment or emotional sensitivity. IV (clinical): uterine hyperstimulation, water retention. | Water retention, tingling in extremities, potential increase in cortisol and prolactin levels. |
