Peptide entry
GHRP-2
Evidence / context
Evidence: Limited. Strong GH-pulse and appetite-signaling profile compared with gentler secretagogues such as Ipamorelin.
Available vial formats
- Conservative 100 mcg once daily, morning fasted (6 units per injection)
- Standard 100 mcg twice daily (6 units per injection)
- Aggressive 150 mcg two to three times daily, short cycle only (9 units per injection)
- Cycle length 6-10 weeks
- Best timing Morning fasted first; pre-bed fasted remains an option.
Reconstitution
- Swab vial tops with alcohol
- Draw 3.0 mL bacteriostatic water
- Inject slowly down vial wall (don't blast powder)
- Gently swirl - do not shake
- Rest 5-10 min to dissolve
- Refrigerate 2-8 C
Dosing, cycle & timing
- Conservative 100 mcg once daily, morning fasted (6 units per injection)
- Standard 100 mcg twice daily (6 units per injection)
- Aggressive 150 mcg two to three times daily, short cycle only (9 units per injection)
- Cycle length 6-10 weeks
- Best timing Morning fasted first; pre-bed fasted remains an option.
Timing: Use morning fasted as the default. Optional pre-bed fasted dosing remains an alternative. Avoid dosing near food, especially carbs, when aiming for a GH pulse.
Support / expected effects
- Strong GH pulse + hunger signal.
- May improve sleep/recovery in responders.
- Sometimes used for bulking phases.
Side effects / tolerability
- Increased hunger (common).
- More prolactin/cortisol risk than Ipamorelin.
- Water retention at higher doses.
Practical tips
- Why fasted: insulin/glucose blunt GH pulse.
- If prolactin-type sides, switch to Ipamorelin.
- Limit to 1-2 doses/day if hunger disruptive.
Storage
Refrigerated: ~45-60 days.
