What Is HGH Frag 176-191?

HGH Frag 176-191 is a short-chain peptide derived from the C-terminal region of the full human growth hormone molecule. Unlike full-length somatropin, this fragment does not replicate the entire biological activity of HGH but has been investigated in experimental models for selective metabolic pathway interactions.

Researchers study this fragment because certain segments of larger hormones may exhibit targeted receptor or signaling activity independent of the complete molecule.

Mechanism of Interest in Research

In laboratory studies, HGH Fragment 176-191 has been examined for its role in:

• Lipolytic signaling models
• Fat metabolism pathway research
• cAMP-mediated cellular responses
• Hormone-receptor interaction assays
• Metabolic regulatory pathway modeling

These studies are conducted under controlled in vitro and preclinical research conditions.

Lyophilized Format & Stability

HGH Frag 176-191 is supplied as a freeze-dried (lyophilized) powder to preserve structural stability and reduce degradation risk during transport.

Storage Recommendations:

• Short-term storage: 2–8°C
• Long-term storage: −20°C
• Protect from light and moisture
• Avoid repeated freeze-thaw cycles

Proper storage is essential to maintain peptide integrity for laboratory use.

Research Applications

HGH Frag 176-191 may be referenced in:

• Adipocyte research models
• Hormonal signaling pathway studies
• Metabolic regulation experiments
• Molecular biology assays
• Receptor-binding investigations

All applications must comply with institutional research standards and local regulations.

Quality Control & Testing

Each batch of laboratory-grade HGH Frag 176-191 typically undergoes:

• High-Performance Liquid Chromatography (HPLC) purity analysis
• Mass spectrometry confirmation
• Batch documentation and labeling verification

Researchers should consult the Certificate of Analysis (COA) for detailed purity and testing information.

Regulatory & Safety Notice

• Not approved by FDA, EMA, or other regulatory agencies
• Not intended for human or animal consumption
• Not a dietary supplement
• Not for cosmetic use
• For laboratory research use only

Handling should be performed by qualified laboratory professionals using appropriate safety procedures and protective equipment.

Frequently Asked Questions (FAQ)

What is HGH Frag 176-191 used for?

HGH Frag 176-191 is used strictly in laboratory research to study metabolic and lipolytic signaling pathways. It is not approved for medical or therapeutic use.

Is HGH Fragment 176-191 approved for human use?

No. It is not approved by regulatory authorities for clinical or human use.

What does “research use only” mean?

“Research use only” indicates that the product is intended exclusively for laboratory experimentation and not for human or animal administration.

How should HGH Frag 176-191 be stored?

Store at 2–8°C for short-term use and at −20°C for long-term storage. Protect from moisture and light exposure.

Is this the same as full human growth hormone?

No. HGH Frag 176-191 is only a small fragment of the complete HGH molecule and does not represent full-length growth hormone.

What purity level is typical?

Laboratory-grade HGH Frag 176-191 is commonly supplied with ≥98% purity verified by HPLC testing. Batch-specific data can be found in the COA.

Does HGH Frag 176-191 require special handling?

Yes. It should be handled by trained laboratory personnel under appropriate laboratory safety protocols.
