Product Overview

HGH191AA Somatropin Nasal Spray is a synthetic peptide analogue mirroring the 191-amino-acid sequence of endogenous human growth hormone (hGH). Supplied in a precision-dosed nasal spray format, this research compound is of interest to scientists studying somatotropic axis function, protein synthesis pathways, adipose tissue metabolism, and tissue regeneration models. Direct Anti Peptide offers this compound for sale with full analytical documentation, making it a preferred choice for researchers seeking verified, laboratory-grade peptide reagents.

Peptide Structure & Amino Acid Sequence

Somatropin (HGH191AA) is a 191-amino-acid polypeptide that structurally replicates the natural sequence of human growth hormone. Its primary structure includes two disulfide bridges critical to tertiary conformation and receptor-binding activity. The intact 191-residue chain is essential for maintaining biological relevance in experimental models exploring GH receptor interactions, downstream IGF-1 signalling, and anabolic pathway research.

Purity & Analytical Verification (HPLC & MS)

Every batch of HGH191AA Somatropin Nasal Spray supplied by Direct Anti Peptide is independently verified to a minimum purity of ≥98% by high-performance liquid chromatography (HPLC). Mass spectrometry (MS) confirmation ensures the molecular integrity of the 191-amino-acid sequence is preserved throughout formulation. Certificates of Analysis (CoA) are available upon request and accompany all research orders, providing full traceability from synthesis to dispatch.

Quality Control & Lyophilization Integrity

While this product is supplied in a ready-to-use nasal spray format rather than lyophilized powder, the underlying peptide active is manufactured under strict GMP-aligned quality control protocols. Each production lot undergoes multi-stage quality assurance including sterile filtration, endotoxin screening, and concentration verification to ensure consistency across batches. Researchers can order with confidence knowing that Direct Anti Peptide maintains rigorous quality standards throughout the supply chain.

Safety, Handling & Laboratory Precautions

This compound is intended exclusively for use by trained research professionals in appropriately equipped laboratory settings. Standard laboratory personal protective equipment (PPE) — including nitrile gloves, safety eyewear, and a lab coat — should be worn at all times when handling this reagent. Avoid contact with skin, eyes, and mucous membranes outside of controlled experimental conditions. This product is not approved for administration to humans or animals and must never be used outside of a certified research environment.

Reconstitution, Packaging & Storage

HGH191AA Somatropin Nasal Spray is supplied pre-formulated in a sterile nasal spray bottle for direct laboratory use. Store at 2–8°C upon receipt and protect from direct light and repeated freeze-thaw cycles. Do not freeze the nasal spray formulation. Once opened, use within the timeframe specified on the product label. Packaging is designed to maintain peptide stability and prevent contamination during research handling. All storage and handling must comply with institutional biosafety guidelines.
