Oxytocin Benefits

  • Enhances social bonding and trust
  • Reduces social anxiety
  • Emotional regulation
  • Potential autism spectrum benefits
  • Stress and anxiety reduction

Hexarelin Benefits

  • Strongest GH pulse among GHRPs
  • Cardioprotective effects
  • Muscle mass and strength gains
  • Fat loss through improved body composition
  • Enhanced recovery from training

Oxytocin Dosing

Intranasal: 20-40 IU per dose, 1-2 times daily|Social Anxiety: 24 IU intranasal 45 min before social situations|Research: 8-40 IU per administration|Clinical: Per physician protocol

Hexarelin Dosing

Standard: 100-200 mcg SC 2-3 times daily|Pre-workout: 100 mcg 30 min before training|Pre-bed: 100 mcg for overnight GH pulse|Cycle: 8-12 weeks then 4 week break (desensitization)

Oxytocin Side Effects

  • Common (Intranasal): Nasal irritation, headache, drowsiness
  • Moderate: Uterine contractions (caution in pregnancy)
  • Rare: Water retention at high doses
  • Contraindications: Pregnancy (non-medical), cardiovascular disease

Hexarelin Side Effects

  • Common: Increased appetite, water retention, tingling
  • Moderate: Cortisol and prolactin elevation (dose-dependent)
  • Notable: Desensitization occurs after 4-16 weeks of continuous use
  • Rare: Numbness in extremities

Research Overview

Oxytocin

Oxytocin has extensive research and is one of the most studied hormonal peptides. FDA-approved for obstetric use. Intranasal formulations being studied for autism spectrum disorder, social anxiety, PTSD, and depression. Complex dose-response relationships being elucidated.

Hexarelin

Hexarelin has extensive pre-clinical and clinical evidence. Multiple human studies confirm potent GH release. Unique cardioprotective properties are well-documented. Note that receptor desensitization limits long-term continuous use.
