Known For

Growth hormone releasing peptide. Similar to GHRP-2 but causes even MORE intense hunger. Strong GH release. The hunger effect is the main distinguishing feature — problematic for fat loss but useful for appetite stimulation.

Mechanism of Action

First-generation GH secretagogue. Strong GH release BUT extreme hunger stimulation + cortisol/prolactin increase. Least selective GHRP.

Body vs. External Supply

🟢 Secretagogue (stimulates natural)

Brand / Trade Names

No pharmaceutical brand Research peptide only WADA prohibited

Typical Research Dosage

100-300mcg per injection, 2-3x daily fasted.

Vial Duration Guide

5mg vial at 300mcg/day = ~17 days.

Recommended Vial Size

★ 5mg vials At 300mcg/day, 5mg = ~17 days ✓. 10mg = 33 days ✓. Same as GHRP-2.

Time to Effects

EARLY: Immediate hunger FULL: 8-12 weeks Immediate: Ravenous hunger 15-20 minutes post-injection. This is unmistakable. Week 2-4: GH-mediated recovery and sleep improvements. Week 8-12: Body composition changes if diet is managed despite hunger. The hunger is the 'effect' you feel first. GH benefits follow the same 8-12 week timeline as other GHRPs.

Contraindications & Do Not Combine

• Do NOT combine with exogenous HGH • Do NOT combine with GHRP-2 or Hexarelin (pick one GHRP) • ⚠️ Do NOT combine with GLP-1 agonists if fat loss is the goal (GHRP-6 hunger directly counteracts appetite suppression)

Common Side Effects

Extreme hunger (40%+ — can be uncontrollable), water retention, cortisol spike, prolactin elevation, flushing, dizziness

Drug Interactions

Somatostatin analogs. Insulin (hunger + hypoglycaemia risk).

Reversibility

Reversible — appetite normalizes quickly, cortisol/prolactin normalize within days

Storage Requirements

Reconstituted: 2-8°C, 14-21 days

State	Condition	Duration
Lyophilised (sealed)	2–8°C	12-24 months
Reconstituted	2-8C	4–6 weeks

Reconstitution Note

Reconstitute with bacteriostatic water (BAC water). Do not shake vigorously -- swirl gently to dissolve. Inject BAC water slowly down the side of the vial to avoid denaturing the peptide.
