Fragment 176-191 Peptide – The Selective HGH Lipolytic Fragment
Fragment 176-191 (HGH Frag) represents the final 16 amino acids of the 191-amino acid growth hormone chain. In the research community, it is exclusively studied for its ability to mimic the lipolytic action of hGH. This peptide allows researchers to investigate fat reduction pathways without the complications of carbohydrate metabolism suppression or glucose intolerance typically associated with full-length growth hormone.
Key Research Areas:
- Targeted Lipid Degradation: Dubbed the “lipolytic fragment,” Frag 176-191 has been observed in animal models to significantly increase fat cell metabolism. It is a primary tool for researchers investigating the reduction of adipose tissue in genetically engineered obese subjects.
- Metabolic Profile Neutrality: One of the most significant aspects of Frag 176-191 is its lack of effect on insulin sensitivity. Unlike full hGH, it does not appear to heighten IGF-1 levels or promote long bone growth, making it a “cleaner” model for fat loss studies.
- Enhanced Molecular Stability: This version includes a tyrosine replacement at the N-terminus. This structural modification—often seen in AOD 9604—is designed to protect the peptide from rapid enzymatic degradation and harsh environmental conditions, such as exposure to gastric acids.
- Disulfide Bond Integrity: The peptide contains a naturally occurring disulfide bond between its two cysteine residues. Researchers hypothesize that this bond is crucial for maintaining structural resilience and ensuring the molecule reaches its target receptors intact.
