Oxytocin Benefits

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

GHRP-6 Benefits

  • Potent GH release stimulation
  • Muscle growth and strength
  • Appetite stimulation (ghrelin pathway)
  • 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

GHRP-6 Dosing

Standard: 100-300 mcg SC 2-3 times daily|Pre-workout: 100 mcg 30 min before training|Pre-bed: 100-200 mcg for overnight GH pulse

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

GHRP-6 Side Effects

  • Common: Increased appetite (significant), water retention, tingling
  • Moderate: Cortisol elevation (dose-dependent), lethargy
  • Rare: Elevated prolactin at high doses

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.

GHRP-6

GHRP-6 has solid pre-clinical and clinical evidence for GH stimulation. Well-characterized pharmacology. More appetite stimulation than Ipamorelin due to ghrelin receptor activation.
