HGH Fragment 176-191 Nasal Spray

Direct Anti Peptide presents HGH Fragment 176-191 Nasal Spray, a high-purity research-grade peptide formulation manufactured to ≥98% purity standards. Designed exclusively for qualified laboratory researchers, this nasal spray delivery format offers a convenient, non-injectable format for controlled peptide studies. 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 synthetic peptide derived from the C-terminal region of human growth hormone (HGH). Specifically, it represents amino acid positions 176 through 191 of the full HGH sequence. In research settings, this fragment has attracted significant scientific interest due to its targeted interaction with adipose tissue pathways and growth hormone receptor mechanisms. The nasal spray format offered by Direct Anti Peptide provides laboratory professionals with a non-invasive delivery medium, eliminating the need for injection-based administration in experimental protocols. This makes it a sought-after research tool among scientists studying metabolic function, body composition dynamics, and energy regulation at the cellular level.

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 chain is isolated from the larger human growth hormone molecule and retains the structural properties associated with the lipolytic region of HGH. The fragment does not carry the full anabolic signaling profile of intact HGH, making it a more targeted research compound for studies focused specifically on fat metabolism and adipose tissue biology. Its disulfide bridge between cysteine residues contributes to its conformational stability, which is preserved through the lyophilization and formulation processes used in production.

Purity & Analytical Verification (HPLC & MS)

Every batch of HGH Fragment 176-191 Nasal Spray available through Direct Anti Peptide is subject to rigorous analytical testing prior to release. High-Performance Liquid Chromatography (HPLC) is used to confirm peptide purity at or above the ≥98% threshold, while Mass Spectrometry (MS) validates the molecular identity and confirms the correct amino acid sequence and molecular weight. These dual-verification methods ensure that researchers receive a compound of consistent quality, free from significant impurities, truncated sequences, or degradation products. Certificates of Analysis (CoA) reflecting these results are available upon request and accompany each order from Direct Anti Peptide.

Quality Control & Lyophilization Integrity

The peptide active ingredient in this formulation is produced via solid-phase peptide synthesis (SPPS) under controlled manufacturing conditions. Lyophilization is employed to preserve structural integrity and extend shelf stability prior to formulation into the nasal spray medium. Quality control checkpoints are applied at each stage of production, including raw material verification, in-process testing, and final product release testing. This multi-stage QC approach ensures that the nasal spray formulation maintains consistent peptide concentration and activity profile across all units supplied by Direct Anti Peptide.

Safety, Handling & Laboratory Precautions

This product is intended exclusively for use by trained research professionals in properly equipped laboratory environments.
