Oxytocin vs HGH Fragment 176-191
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.

HGH Fragment 176-191 is the fat-reducing portion of the growth hormone molecule. Unlike AOD-9604 (which has an additional tyrosine), this is the exact fragment of HGH responsible for lipolytic effects.

| Aspect | Oxytocin | HGH Fragment 176-191 |
|---|---|---|
| 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. | Mimics the lipolytic region of growth hormone, stimulating fat breakdown and inhibiting lipogenesis without affecting blood sugar or promoting growth. Works independently of GH receptors. |
| Typical Dosage | Intranasal: 20-40 IU (international units) for social/anxiolytic effects. Clinical uses (labor induction) require IV administration under medical supervision. | Typical dosing: 250-500mcg daily, often split into 2-3 doses. Usually administered on empty stomach, often with fasted cardio. |
| Administration | Intranasal spray for behavioral effects. IV only in clinical settings. Sublingual also possible. Best used situationally rather than continuously. | Subcutaneous injection. Best results when used fasted and combined with exercise. Avoid eating for 30 minutes post-injection. |
| Side Effects | Intranasal: headache, nasal irritation, drowsiness. May cause over-attachment or emotional sensitivity. IV (clinical): uterine hyperstimulation, water retention. | Generally well-tolerated. May cause injection site irritation, temporary lethargy, or headache. Does not affect blood glucose significantly. |
