Quickstart highlights
GHRP-2 at 300 μg produces approximately 5–7 ng/mL peak GH serum concentrations when injected in fasted state; combined with CJC-1295 (300 μg simultaneously), peak GH rises to approximately 15–20 ng/mL.
Concentration: 2 mg/mL (10 mg vial + 5 mL bacteriostatic water). At 2 mg/mL: 200 μg = 10 units, 300 μg = 15 units per injection. At 300 μg 3x daily, one 10 mg vial lasts approximately 11 days. Monitor monthly morning cortisol at 2–3x daily dosing frequency. Refrigerate; use within 28 days.

Reconstitution steps
Draw 5 mL bacteriostatic water in two 2.5 mL draws; inject slowly down vial wall. Swirl gently until fully dissolved; do not shake. Final concentration: 2 mg/mL. Label with date; refrigerate at 2–8 °C. Use within 28 days.

Protocol overview & cycle notes
Sustain elevated GH pulse frequency through 2–3x daily GHRP-2 injections using the efficient 10 mg vial, designed for patients who have established GHRP-2 tolerance and require a high-volume supply.
Cycle length: 12 weeks on.
Off-cycle: 4–6 weeks off; check morning cortisol before restarting.
Storage & handling
Lyophilized: store below 25 °C. Reconstituted at 2 mg/mL: refrigerate 2–8 °C; use within 28 days. At 300 μg 3x daily, one 10 mg vial lasts approximately 11 days.
Injection & tracking tips
At 300 μg 3x daily, one 10 mg vial lasts ~11 days — plan 8 vials for a full 12-week cycle. GHRP-2 at 2–3x daily frequency should be monitored with monthly morning cortisol labs. Preferentially inject in the morning fasted, pre-workout (fasted 2+ hours), and at bedtime.
Tracking
Logging helps you and your provider spot patterns and adjust dose or timing.
Track morning serum cortisol monthly at 2–3x daily dosing. Measure IGF-1 every 6 weeks. Record subjective hunger and energy levels after each injection for the first 4 weeks.Log your cycle in the calculator →
How this works & references
GHRP-2 at 300 μg produces approximately 5–7 ng/mL peak GH serum concentrations when injected in fasted state; combined with CJC-1295 (300 μg simultaneously), peak GH rises to approximately 15–20 ng/mL. The 10 mg vial provides approximately 11 days at 300 μg 3x daily, making 8–9 vials necessary for a full 12-week cycle at maximum frequency.
Frequently asked questions How many 10 mg vials do I need for a 12-week cycle at 300 μg 3x daily?
At 300 μg × 3 × 84 days = 75.6 mg total. At 10 mg/vial, you need approximately 8 vials for the full 12-week cycle. Is 3x daily GHRP-2 safe long-term?
Chronic 3x daily use (beyond 12 weeks) risks HPA axis habituation and persistent cortisol elevation. The 12-week cycle with 4–6 week off-periods is strongly recommended. Monitor morning cortisol monthly. Why is the 10 mg vial better for high-frequency use than the 5 mg?
At 3x daily dosing, a 5 mg vial lasts only 5–6 days — requiring frequent reconstitution. The 10 mg vial provides 11 days per reconstitution, reducing sterility risk and handling time by approximately 50%. Should I rotate injection sites with GHRP-2?
Yes — rotate between abdomen, outer thigh, and upper arm for each injection. GHRP-2 at 3x daily creates 21 injection events per week; consistent site rotation prevents subcutaneous fibrosis and absorption irregularities. Does GHRP-2 affect insulin sensitivity?
Acute GH elevation temporarily decreases insulin sensitivity for 2–4 hours post-injection via GH-induced lipolysis and FFA release. At therapeutic doses with proper cycling, this effect normalizes during off-cycles. Monitor fasting glucose monthly during active use.
