Overview
GHRP-6 is a synthetic hexapeptide functioning as a growth hormone secretagogue that binds to the ghrelin receptor (GHS-R1a). It stimulates pulsatile GH release from the pituitary gland while maintaining physiological feedback controls, elevating IGF-1 levels with potential anabolic benefits.
Quick Start
– Reconstitution: Add 3.0 mL bacteriostatic water → ~1.67 mg/mL concentration
– Typical daily range: 300–900 mcg total (split into 3 doses with gradual titration)
– Measurement: 1 unit = 0.01 mL ≈ 16.7 mcg on a U-100 insulin syringe
– Storage: Lyophilized at −20 °C (−4 °F); reconstituted at 2–8 °C (35.6–46.4 °F) for up to 7 days
Dosing Protocol
| Phase | Dose per Injection | Units (per injection) |
|---|---|---|
| Weeks 1–2 | 100 mcg | 6 units (0.06 mL) |
| Weeks 3–4 | 200 mcg | 12 units (0.12 mL) |
| Weeks 5–12 | 300 mcg | 18 units (0.18 mL) |
Frequency: Three subcutaneous injections daily, spaced at least 4 hours apart (morning, midday, bedtime). GHRP-6 has a half-life of approximately 2.5 hours. Each injection should occur on an empty stomach — 2–3 hours after meals, 30 minutes before eating — to maximize GH release.
Reconstitution Steps
1. Draw 3.0 mL bacteriostatic water with a sterile syringe
2. Inject slowly down the vial wall to avoid foaming; do not shake
3. Gently swirl or roll the vial until powder completely dissolves
4. Label with date and concentration, then refrigerate at 2–8 °C, protected from light
5. Use within 7 days of reconstitution for optimal potency
Supplies Needed (12-Week Protocol)
– GHRP-6 Vials (5 mg): ~13 vials
– Insulin Syringes (U-100): ~252 syringes (3 boxes of 100)
– Bacteriostatic Water (10 mL bottles): 4 bottles
– Alcohol Swabs: 6 boxes (100-count each)
How It Works
GHRP-6 binds to the GHS-R1a receptor in the pituitary and hypothalamus, triggering acute pulsatile growth hormone release while reducing somatostatin’s inhibitory effects. As GH and IGF-1 rise, endogenous somatostatin increases to prevent excessive elevation, maintaining physiological feedback control.
The compound exhibits cytoprotective properties through CD36 receptor interactions on immune and muscle cells, activating cell-survival signaling cascades (PI3K/Akt pathways) that protect tissues from oxidative stress and inflammation.
Potential Benefits
– Muscle Growth & Fat Loss: Elevated GH and IGF-1 support increased lean mass and reduced fat mass
– Enhanced Recovery: Improved sleep architecture and faster tissue repair
– Appetite Stimulation: Increases hunger due to ghrelin receptor activation
– Tissue Protection: Preclinical studies show reduced scar formation, cardioprotection, and neuroprotection
– Joint Health: May support collagen synthesis and connective tissue repair through elevated IGF-1
Potential Side Effects
– Transient mild increases in cortisol and ACTH (typically not clinically significant)
– Increased appetite and potential water retention
– Occasional injection-site reactions (redness, itching, mild swelling)
– Possible transient dizziness or flushed feeling immediately after injection
– Generally well-tolerated in research doses with no major safety concerns reported
Injection Technique
– Clean the vial stopper and injection site with alcohol swabs; allow to dry completely
– Use a new sterile insulin syringe; check for air bubbles
– Rotate between abdomen (2+ inches from navel), outer thighs, and upper arms
– Insert needle at 45–90° angle into subcutaneous tissue
– Inject slowly and steadily; hold for several seconds before withdrawing
– Immediately dispose of used syringes in a puncture-proof sharps container
Storage Instructions
– Lyophilized: Store at −20 °C (−4 °F) in dry, dark conditions with desiccant if available
– Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F) and use within 7 days
– Avoid freeze-thaw cycles; do not refreeze reconstituted solution
– Allow vials to reach room temperature before opening to minimize condensation
Lifestyle Factors
– Nutrition: Maintain protein intake of 1.6–2.2 g/kg body weight; time carbohydrates and fats away from injections
– Training: Combine resistance training with moderate cardiovascular activity
– Sleep: Prioritize 7–9 hours of quality sleep
– Hydration: Maintain proper hydration to support metabolism
– Stress Management: Incorporate stress-reduction techniques
Important Notes
– Use new sterile insulin syringes for each injection; dispose in a sharps container
– Rotate injection sites systematically (abdomen, thighs, upper arms) to reduce lipohypertrophy
– Inject slowly and wait several seconds before withdrawing the needle
– GHRP-6 may increase appetite due to ghrelin-mimicking properties
– Document daily doses, timing, and sites for consistency
