Overview
GHRP-6 is a first-generation synthetic hexapeptide growth hormone secretagogue renowned for triggering dramatic growth hormone release alongside intense appetite stimulation.
What problem it targets: It targets low growth hormone levels, slow athletic recovery, muscle wasting, and severe appetite loss in individuals struggling to consume enough calories to gain mass.
What It Does
• Potently activates ghrelin receptors: Strongly binds pituitary and hypothalamic GHS-R1a receptors, eliciting a massive, immediate pulse of endogenous growth hormone.
• Induces acute, intense hunger (hyperphagia): Mimics the hunger hormone ghrelin in the hypothalamus, triggering ravenous food cravings within 20 to 30 minutes of administration.
• Enhances gut motility and protective tissue repair: Stimulates stomach emptying and mucosal blood flow, aiding digestion and nutrient assimilation during heavy training cycles.
• Realistic expectations: Delivers immediate, pronounced hunger alongside rapid GH release. Produces mild water retention and increases in prolactin and cortisol at higher doses.
Reconstitution
| Vial size | BAC water / Solvent | Concentration |
|---|---|---|
| 5 mg | + 1 mL | 5 mg/mL |
| 10 mg | + 2 mL | 5 mg/mL |
Protocol
| Phase | Frequency | Dose | Units (2 mg/mL) | Notes |
|---|---|---|---|---|
| Weeks 1–2 | 2×/day | 100 mcg | 5u | Expect strong hunger ~20–30 min after dosing. AM fasted + pre-bed. |
| Weeks 3–12 | 2–3×/day | 200 mcg | 10u | Working dose. ~1 mcg/kg saturates the GH response; more mainly adds cortisol/prolactin. |
| Off | 4 weeks | – | – | Prevents ghrelin-receptor downregulation. Cycle: 8–12 weeks on / 4 weeks off. Timing: Empty stomach, no food 30 min after. The hunger surge is the tell that it’s working (and why it suits bulking). Saturation: plateaus ~1 mcg/kg. Women: Women need more GH but get a bigger bump from ghrelin-types, though these raise prolactin, which can disrupt cycles/ovulation (watch for missed periods). Oral estrogen blunts IGF-1. Men: Men overshoot the IGF-1 ceiling more easily (aim mid-normal); high prolactin lowers libido and testosterone, switch to a cleaner option if it climbs. |
Handling & Stacking
- Strong appetite and improved sleep early; recovery and body-composition gains over 8–12 weeks.
- Best in a GHRH + GHRP stack during a gaining phase.
- Supply math 5mg → 7 vials | 10mg → 4 vials (12-wk @ 200 mcg × 2/day)
Safety & Patient Education
- IGF-1 (baseline + Week 8 + end) Fasting glucose / HbA1c (baseline + end), especially given appetite effect Prolactin if symptomatic Age-appropriate cancer screening before starting Out of range?
- IGF-1 above your age range = too much growth signal (feeds hidden cancer, enlarges organs) → drop the dose; rising glucose/HbA1c = sugar creeping up.
