Overview

Known for

GHRH analogue. FDA-approved specifically to reduce visceral (abdominal) fat in HIV-associated lipodystrophy. Targets belly fat specifically. Also improves cognitive function in some studies.

Mechanism

Modified GHRH analog — stimulates pulsatile GH release. FDA-approved specifically for HIV-associated lipodystrophy (visceral fat reduction).

Half-life

~26 minutes (SubQ) | ~38 minutes (IV)
Protocol

1-2mg daily SubQ. FDA dosing is 2mg/day.

Time to effects

EARLY: 2-4 weeks

FULL: 12-26 weeks

Week 2-4: GH levels increase measurably on blood work (IGF-1).

Week 4-8: Subtle reduction in visceral fat. May notice waistline changes.

Week 12-26: Significant visceral fat reduction. Clinical trials showed meaningful reduction in trunk fat at 26 weeks. Cognitive improvements reported in some studies.

Specifically targets belly fat — don't expect overall weight loss like GLP-1 agonists. Minimum commitment: 12 weeks.

Recommended vial
  • 10mg or 20mg vials

At 2mg/day (FDA dose), 5mg = 2.5 days, 10mg = 5 days ✓, 20mg = 10 days ✓. 2mg = 1 day (impractical). Higher mg vials needed due to high daily dose.

Safety

Reversibility
Fully Reversible
Side effects

Injection site reactions (20-30%), joint pain (13%), pruritus (7%), peripheral edema, hyperglycaemia in pre-diabetic patients

Interactions

Insulin/anti-diabetic drugs (may antagonize glucose control), cortisone, somatostatin analogs

Handle with research caution

  • Do NOT combine with exogenous HGH
  • Do NOT combine with CJC-1295 or Sermorelin (all GHRH receptor agonists — pick one)
