Developed specifically for qualified laboratory researchers, this product eliminates the need for manual preparation and delivers consistent, reproducible results across experimental protocols. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

HGH Fragment 176-191 is a stabilised analogue of the C-terminal region of human growth hormone (HGH), corresponding to amino acids 176 through 191 of the full HGH sequence. In controlled laboratory settings, this peptide has been widely studied for its role in lipid metabolism, fatty acid oxidation pathways, and insulin sensitivity modelling. The pre-mixed pen format offered by Direct Anti Peptide provides researchers with a streamlined, time-efficient solution without sacrificing analytical quality. Available as a single cartridge unit, this product is designed to meet the demands of modern peptide research workflows.

Peptide Structure & Amino Acid Sequence

HGH Fragment 176-191 corresponds to the following amino acid sequence: Tyr-Leu-Arg-Ile-Val-Gln-Cys-Arg-Ser-Val-Glu-Gly-Ser-Cys-Gly-Phe. This 16-amino acid fragment is isolated from the lipolytic domain of the parent HGH molecule and is recognised in the research literature for its targeted interaction with adipose tissue pathways. The fragment retains the structural characteristics necessary for receptor-level investigation in metabolic and endocrinological research contexts.

Purity & Analytical Verification (HPLC & MS)

Every batch of HGH Fragment 176-191 supplied by Direct Anti Peptide undergoes rigorous analytical verification prior to dispatch. Purity is confirmed at ≥98% using high-performance liquid chromatography (HPLC), while mass spectrometry (MS) is employed to validate molecular identity and confirm structural integrity. These dual-method quality controls ensure that each unit delivered to the researcher meets the exacting standards required for reproducible, publication-quality laboratory investigations.

Quality Control & Lyophilisation Integrity

Prior to pre-mixing, the peptide is produced via solid-phase peptide synthesis (SPPS) and lyophilised under controlled conditions to preserve structural stability and bioactivity for research purposes. The lyophilisation process removes residual moisture, extending shelf life and maintaining compound integrity throughout storage and transit. Each pre-mixed cartridge is sealed under sterile manufacturing conditions to prevent contamination and ensure consistent peptide concentration across research applications.

Safety, Handling & Laboratory Precautions

This product is intended exclusively for use by trained research professionals operating within a certified laboratory environment. Standard laboratory personal protective equipment (PPE) — including gloves, eye protection, and appropriate lab attire — should be worn when handling peptide cartridges. Researchers should adhere to all institutional biosafety protocols and relevant local regulations governing the handling of synthetic peptides. This product is not approved for use in humans or animals under any circumstances.

Reconstitution, Packaging & Storage

The HGH Fragment 176-191 Pre-Mixed Pen includes a cartridge that has been pre-mixed with bacteriostatic water, eliminating the need for manual reconstitution in the laboratory. The complete kit contains:

• 1 x Pre-Mixed Peptide Cartridge (HGH Fragment 176-191 5mg in bacteriostatic water)
• 1 x Peptide Cartridge Pen
• 1 x Pen Carry Case
• 3 x Pen Needle Tips

Store the pre-mixed cartridge refrigerated at 2–8°C and protect from direct light and moisture. Keep away from heat sources and out of reach of unauthorised personnel. Once in use, follow standard laboratory storage protocols for peptide solutions in aqueous media.

Intended Research Use & Market Positioning

HGH Fragment 176-191 is actively investigated in academic and commercial research settings focused on metabolic biology, lipolysis modelling, adipogenesis, and insulin sensitivity studies. Its well-characterised interaction with lipid metabolism pathways makes it a frequently referenced compound in obesity-related research and energy homeostasis investigations. Direct Anti Peptide positions this pre-mixed pen format as the premium choice for researchers who require precision, convenience, and verified purity in a single integrated solution.
