GHRP-6 Dosage Guide: Protocols, Timing & How Much to Take (2026)

From Peptidepedia, the trusted peptide wiki.

Dosage Protocols

No FDA-approved dosing guidelines exist for GHRP-6. The following protocols are derived from clinical research and community experience:

Saturation Dose Concept: The saturation dose for GHRP-6 is approximately 1 mcg/kg of body weight, which translates to roughly 100 mcg per injection for a 100 kg individual. Doses beyond this point do not proportionally increase GH release but do escalate cortisol and prolactin co-secretion. This makes the saturation dose the optimal ceiling for each individual injection.

Beginner Protocol

100 mcg once or twice daily (morning and bedtime), for 8 to 12 weeks. The bedtime dose is the priority, as it amplifies the natural nocturnal GH surge.

Intermediate Protocol

100 mcg two to three times daily (morning, midday, bedtime), for 8 to 12 weeks. Each injection should be separated by at least 3 hours to allow GH pulsatility to normalize between doses.

Advanced Protocol

100 to 150 mcg three times daily, often combined with a GHRH analog such as CJC-1295 (Mod GRF 1-29) at 100 mcg per injection, for 12 to 16 weeks.

Cycling Recommendations

Cycling is recommended: 8 to 16 weeks on followed by 4 to 8 weeks off. See the peptide cycling guide for structured protocols. Prolonged continuous use beyond 16 weeks may result in diminishing GH response due to receptor desensitization. Rotating to another GHRP (such as GHRP-2 or ipamorelin) during off-cycles is a common strategy.

Frequently Asked Questions

The commonly cited saturation dose is approximately 1 mcg/kg of body weight, which translates to roughly 100 mcg per injection for most adults. Doses are typically administered two to three times daily on an empty stomach. Exceeding the saturation dose does not proportionally increase GH release but does elevate cortisol and prolactin.

The most common side effect is intense hunger shortly after injection. Other effects include mild water retention, transient flushing or dizziness, and tingling in the extremities. At doses above the saturation threshold, GHRP-6 can elevate cortisol and prolactin levels. These effects are generally dose-dependent and transient.

Ipamorelin is more selective, releasing GH without meaningfully affecting cortisol, prolactin, or appetite at standard doses. GHRP-6 produces a comparable GH pulse but with significant appetite stimulation and modest cortisol and prolactin elevation. Ipamorelin is generally preferred for cleaner side effect profiles, while GHRP-6 may suit those seeking appetite stimulation.

GHRP-6 is administered via subcutaneous injection, typically into abdominal fat, the thigh, or the deltoid. It should be injected on an empty stomach, at least 30 minutes before eating or 2 or more hours after a meal, as elevated insulin blunts GH release. The most common protocol is two to three injections daily.
