Known For

The fat-burning fragment of human growth hormone. Same active sequence as AOD 9604. Stimulates lipolysis without affecting blood sugar or promoting growth.

Mechanism of Action

Synthetic fragment of HGH (amino acids 176-191). Proposed fat-burning portion of HGH without growth effects. Very similar to AOD 9604.

Body vs. External Supply

🟡 Natural/Topping Up

Brand / Trade Names

No pharmaceutical brand Research peptide only

Typical Research Dosage

250-500mcg/day SubQ, typically split AM/PM. Must be fasted.

Vial Duration Guide

5mg vial at 500mcg/day = 10 days.

Recommended Vial Size

★ 5mg (only size) At 500mcg/day = 10 days ✓. At 250mcg/day = 20 days ✓. No shelf life issues.

Time to Effects

EARLY: 4-6 weeks FULL: 12-16 weeks Same timeline as AOD 9604 (same active fragment). Subtle fat metabolism effects rather than dramatic changes. Minimum commitment: 8-12 weeks. Modest standalone results.

Research Disclaimer

Almost all data is preclinical (animal or in-vitro). No large-scale randomised controlled human trials are available for most compounds on this catalogue. This information is provided for research reference only.

Storage Requirements

Reconstituted: 2-8°C, 14-21 days

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