Compound Profiles

HGH Fragment 176-191

Growth Hormone Fragment | Fat Loss Peptide

Mimics the lipolytic region of human growth hormone by stimulating fat breakdown through beta-3 adrenergic receptor pathways. Unlike full HGH, it does not bind the growth hormone receptor, so it does not increase IGF-1 levels or interfere with glucose metabolism.

Sermorelin

GHRH Analog | Growth Hormone Releasing Hormone

Subcutaneous injection provides optimal bioavailability for binding GHRH receptors, stimulating pulsatile GH release while maintaining hypothalamic-pituitary axis integrity and allowing natural somatostatin negative feedback..

Frequently Asked Questions

Can I take HGH Fragment 176-191 with Sermorelin?

Yes, but with caution. Both HGH Fragment 176-191 and Sermorelin affect insulin sensitivity or blood glucose. Monitor fasting glucose and HbA1c. Consider adding an insulin sensitizer (metformin/berberine). Regular monitoring is advised.

Is HGH Fragment 176-191 and Sermorelin safe together?

Based on pharmacological analysis, this combination is considered monitor. However, shared safety flags include: carcinogenic risk, insulin disrupting, teratogenic. Monitor accordingly.

What are the interactions between HGH Fragment 176-191 and Sermorelin?

Both HGH Fragment 176-191 and Sermorelin affect insulin sensitivity or blood glucose. Monitor fasting glucose and HbA1c. Consider adding an insulin sensitizer (metformin/berberine). This assessment has 47% confidence and is inferred from pharmacological mechanism analysis.

How should I time HGH Fragment 176-191 and Sermorelin?

HGH Fragment 176-191 has a half-life of 15-20 minutes and Sermorelin has a half-life of 10-12 minutes. No specific timing requirements identified for this combination, but separating administration can help monitor individual effects.

This interaction analysis is compiled from research literature and pharmacological mechanism data. This assessment is inferred from known mechanisms and may not reflect all real-world outcomes. Always consult a healthcare professional before combining compounds.

COACH'S BOARD / KEY POINTS

HGH Fragment 176-191 and AOD-9604 are the same molecular structure. A 15-amino-acid sequence (positions 176–191) derived from the C-terminus of human growth hormone, with identical 1817 Da molecular weight and amino acid composition.
The AOD-9604 designation originated from clinical trials conducted by Metabolic Pharmaceuticals between 2004 and 2007, while Fragment 176-191 remains the standard biochemical nomenclature used in research supplier catalogs and academic publications.
Both compounds failed to achieve FDA approval for obesity treatment after Phase IIb trials showed insufficient weight loss efficacy (2.6% vs 1.8% placebo) despite acceptable safety profiles and no IGF-1 elevation.
The peptide retains lipolytic activity by activating beta-3 adrenergic receptors on adipocytes without binding to growth hormone receptors. Making it valuable for metabolic research isolating fat mobilization from anabolic growth signaling.
Lyophilized Fragment 176-191 maintains >95% purity for 21 days post-reconstitution when stored at 2–8°C in amber vials, but oxidation at cysteine residues accelerates degradation beyond 28 days or after freeze-thaw cycles.
Research labs should specify Fragment 176-191 or AOD-9604 based on protocol citation requirements rather than assuming functional differences. The molecular identity is identical across suppliers meeting GMP synthesis standards.

RESEARCH

Research and Development of HGH Fragment 176-191

The focus of research on HGH Fragment 176-191 lies in its targeted effects on fat reduction and metabolic processes without affecting human growth. Initially studied as part of broader research on human growth hormone, scientists identified that the amino acid sequence from 176 to 191 held specific fat-reducing properties. This led to the development of the isolated HGH fragment, which has since shown encouraging results in studies. Multiple studies, including those conducted in Saudi Arabia and other research institutions, have shown that HGH Fragment 176-191 can influence fat metabolism effectively. According to a Saudi research team, the peptide had a notable impact on reducing body fat in test subjects, with limited side effects compared to full HGH. [5] Scientific journals and publications have frequently referenced HGH Fragment 176-191. For example, studies published on PubMed highlight the potential of this fragment in managing obesity and reducing body fat percentage without impacting other body systems. Articles also discuss how HGH Fragment 176-191 affects enzymes involved in fat breakdown. [1] [4]
