GHRP-2 vs Oxytocin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
GHRP-2
Growth Hormone Releasing Peptide 2 (GHRP-2) is considered one of the most potent GHRPs available. It provides strong GH release with moderate hunger increase compared to GHRP-6.
Full details →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 →Side-by-Side Comparison
| Aspect | GHRP-2 | Oxytocin |
|---|---|---|
| Mechanism | Binds to the ghrelin receptor (GHS-R) to stimulate GH release from the pituitary. Also has some direct effects on the hypothalamus. Causes less appetite increase than GHRP-6. | 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 | Typical dosing: 100-300mcg administered 2-3 times daily. Often stacked with GHRH peptides for enhanced GH release. | Intranasal: 20-40 IU (international units) for social/anxiolytic effects. Clinical uses (labor induction) require IV administration under medical supervision. |
| Administration | Subcutaneous injection on an empty stomach. Can be used at bedtime to enhance natural GH pulse during sleep. | Intranasal spray for behavioral effects. IV only in clinical settings. Sublingual also possible. Best used situationally rather than continuously. |
| Side Effects | Moderate hunger increase, water retention, potential prolactin and cortisol elevation (less than GHRP-6), tingling sensations. | Intranasal: headache, nasal irritation, drowsiness. May cause over-attachment or emotional sensitivity. IV (clinical): uterine hyperstimulation, water retention. |
