GHRP-6 is a synthetic peptide that boosts growth hormone (GH) release by mimicking ghrelin. This protocol outlines a three-times-daily subcutaneous injection regimen, gradually increasing the dose over 12 weeks to optimize GH secretion and support various physiological benefits.
- Potent growth hormone secretagogue.
- Requires 3 daily injections due to short half-life.
- May increase appetite due to ghrelin mimetic properties.
- Administer on an empty stomach for maximum GH release.
- Often titrated from 100mcg to 300mcg per injection.
Reconstitution
Vial strength

Bacteriostatic water
3 mL
Concentration
3.33 mg/mL
1 unit = 0.01 mL = 33.3 mcg
- 1Draw 3.0 mL of bacteriostatic water using a sterile syringe.
- 2Inject the water slowly down the inside wall of the GHRP-6 vial to prevent foaming.
- 3Avoid shaking the vial; gently swirl or roll it until all the powder is completely dissolved.
- 4Label the reconstituted vial with the date and concentration, then store it in the refrigerator (2–8 °C), protected from light.
- 5Use the reconstituted solution within 7 days for optimal potency.

How it works
GHRP-6 functions by acting as a synthetic ghrelin mimetic, binding to the growth hormone secretagogue receptor (GHS-R1a) in the pituitary gland and hypothalamus. This interaction triggers a pulsatile release of growth hormone (GH) from somatotroph cells and reduces the inhibitory effects of somatostatin on GH secretion. Unlike continuous GH administration, GHRP-6 maintains the body's natural feedback loops, preventing excessive GH levels. It also exhibits additional benefits by activating cell-survival pathways through the CD36 receptor, offering protection against oxidative stress and inflammation in various tissues, such as the heart and brain, and aiding in wound healing.
Reported effects
- Support for muscle growth and fat loss
- Enhanced recovery and improved sleep
- Potential appetite stimulation
- Tissue protective effects (e.g., cardioprotection, neuroprotection)
- Improved joint and connective tissue health
Reported side effects
- Transient mild increases in cortisol and ACTH
- Increased appetite and potential water retention
- Injection-site reactions (redness, itching, swelling)
- Possible transient dizziness or flushed feeling after injection
Storage
Lyophilised (unmixed)
Store at -20 °C (-4 °F) in dry, dark conditions. Avoid freeze-thaw cycles.
After reconstitution
Refrigerate at 2-8 °C (35.6-46.4 °F) and use within 7 days. Protect from light.
Supplies
| Peptide vials | Approximately 7 x 10 mg GHRP-6 vials for a 12-week protocol with gradual titration. |
|---|---|
| Insulin Syringes (U-100) | Roughly 252 syringes (3 x 100-count boxes) for a 12-week protocol. |
| Bacteriostatic Water | Approximately 21 mL (3 x 10 mL bottles) for reconstituting 7 vials. |
| Alcohol Swabs | Around 504 swabs (6 x 100-count boxes) for a 12-week protocol. |
Important notes
- Use a new sterile insulin syringe for each injection and dispose of it properly in a sharps container.
- Rotate injection sites regularly (abdomen, thighs, upper arms) to avoid irritation.
- Inject slowly and pause before withdrawing the needle.
- GHRP-6 can increase appetite due to its ghrelin-like activity.
- Maintain detailed records of doses, timing, and injection sites for consistency.
Frequently asked questions
Why is GHRP-6 injected three times daily?
GHRP-6 has a short half-life of about 2.5 hours. Multiple daily injections, spaced at least 4 hours apart, are necessary to maintain sustained elevation of growth hormone levels, which is more effective than a single daily dose.
Should I inject GHRP-6 on an empty stomach?
Yes, it is recommended to inject GHRP-6 on an empty stomach, typically 2-3 hours after a meal and 30 minutes before eating your next meal. This helps maximize growth hormone release, as food intake can blunt its effects.
What should I do if I notice injection site irritation?
To minimize local irritation or lipohypertrophy, always rotate your injection sites. Optimal areas include the abdomen (at least two inches from the navel), outer thighs, and upper arms. Ensure alcohol swabs dry completely before injecting.
What are the common side effects of GHRP-6?
Common side effects can include a temporary increase in appetite, mild water retention, and localized reactions at the injection site such as redness or itching. Some individuals might experience a transient flushed feeling or dizziness immediately after injection.
