Dosage overview

Typical dose 100-300 mcg per injection
Frequency 2-3 times daily on an empty stomach
Cycle length 8-12 weeks, followed by a 4-week break

Dosing notes

Inject subcutaneously, typically into the abdomen, at least 2 hours after the previous meal. Wait 20 to 30 minutes after injection before eating to avoid insulin-mediated blunting of the GH response. The intense hunger that follows within 15 to 20 minutes of injection makes pre-meal timing essential for practical compliance. Users who inject in a fasted state and then eat a high-protein meal capitalize on the anabolic window created by simultaneous GH elevation and nutrient availability. The most common timing windows are morning (fasted upon waking), pre-workout (45 to 60 minutes before training), and pre-sleep (2 hours after last meal). Stacking with a GHRH analog such as CJC-1295 or modified GRF(1-29) substantially amplifies GH output and is standard practice in research protocols. Users who find GHRP-6's appetite effect unmanageable should consider GHRP-2, which produces similar GH stimulation with notably less appetite stimulation, or ipamorelin, which is the most selective GHRP with minimal appetite and cortisol effects.

Important safety information

Dosage ranges listed above are based on available research data and reported protocols. Individual dosing should be determined by a qualified healthcare provider based on your specific health profile, goals, and response to treatment.

  • Start at the lowest effective dose and titrate up gradually
  • Monitor for side effects, especially during dose increases
  • Do not exceed researched dose ranges without medical supervision
  • This is a research compound — human dosing guidelines are not FDA-established
