Fragment 176-191

HGH Frag 176-191 • AOD-9604 Fragment

A 16-amino acid fragment of human growth hormone that selectively promotes fat metabolism without the side effects of full HGH. Research suggests targeted fat loss properties.

Mechanism

Fragment of human growth hormone (amino acids 176-191) that promotes fat breakdown without affecting blood sugar or growth. Selectively targets fat cells.

Half-Life

30 minutes

Administration

Subcutaneous

Technical Protocol

Fragment 176-191: Comprehensive Research Guide

Overview

Fragment 176-191 (also known as HGH Frag 176-191 or AOD-9604 Fragment) is a 16-amino acid peptide derived from the C-terminal region of human growth hormone (amino acids 176-191). This fragment has been studied for its selective fat-burning properties without the systemic effects of full HGH.

Mechanism of Action

Selective Fat Metabolism

  • Lipolysis: Promotes breakdown of stored fat (triglycerides)
  • Fat Cell Targeting: Specifically targets adipocytes (fat cells)
  • No Growth Effects: Does not stimulate growth hormone receptors
  • Metabolic Enhancement: Increases metabolic rate in fat tissue

Key Differences from HGH

  • No Blood Sugar Impact: Does not affect glucose metabolism
  • No Growth Stimulation: Does not promote muscle or bone growth
  • Targeted Action: Primarily affects fat cells
  • Shorter Half-Life: Rapid clearance from system

Research Applications

Fat Loss Research

  • Targeted Fat Reduction: May reduce stubborn fat deposits
  • Metabolic Rate: Increases fat metabolism
  • Body Composition: Improves body fat percentage
  • Spot Reduction: Potential for localized fat reduction

Comparison to AOD-9604

  • Similar Structure: Related to AOD-9604
  • Different Effects: May have distinct mechanisms
  • Research Status: Both under investigation

Dosage Protocols

Standard Protocol

  • Dose: 200-500 mcg daily
  • Typical: 300 mcg twice daily
  • Timing: Morning and evening
  • Administration: Subcutaneous injection

Cycle Recommendations

  • Duration: 8-12 weeks
  • Cycles: 8 weeks on, 4 weeks off
  • Stacking: Often combined with other peptides

Side Effects

  • Minimal: Generally well-tolerated
  • Injection Site: Mild irritation possible
  • No Hormonal: Does not affect hormone levels
  • No Blood Sugar: Safe for diabetics

Storage

  • Temperature: 2-8°C (refrigerated)
  • Light: Protect from light
  • Reconstituted: Stable for 2-3 weeks refrigerated
