DOWNLOAD FULL REPORT (PDF)HGH 191AA (Somatropin) is a recombinant form of human growth hormone (hGH) consisting of 191 amino acids in a sequence identical to endogenous pituitary growth hormone. In research environments, Somatropin is used to investigate growth hormone receptor signaling, insulin-like growth factor 1 (IGF-1) regulation, tissue growth, and metabolism-related pathways in a variety of experimental models.
This compound is intended strictly for controlled laboratory research by qualified professionals. It is not labeled, marketed, or approved for human or veterinary use, and no claims are made regarding its safety or effectiveness for performance, physique enhancement, or any therapeutic purpose.
Somatropin (HGH 191AA) is a polypeptide hormone produced via recombinant DNA technology to match the natural 191–amino acid human growth hormone. In experimental systems, it can:
- Bind to growth hormone receptors (GHR) in target tissues
- Influence downstream JAK–STAT and related signal-transduction pathways
- Modulate expression of IGF-1 and associated growth factors
- Serve as a reference standard for assays studying GH bioactivity and pharmacology
Because of its well-characterized structure and receptor interactions, Somatropin is commonly used in endocrine, metabolic, and tissue-growth research frameworks, especially where precise GH receptor activation is needed.
All peptides are supplied as sterile, lyophilized powder and are stable when handled correctly.
- On arrival: Store vials in a cool, dry place away from heat and direct sunlight.
- Long-term (powder): For optimal longevity, keep lyophilized peptides refrigerated to help maintain integrity.
- After reconstitution: Use an appropriate research diluent (for example, BAC water). Store the reconstituted solution in the refrigerator and use within 20–30 days for best stability.
Note: Minimize exposure to moisture and repeated freeze–thaw cycles. Follow your institution's safety procedures when handling research materials.
Q1: What is HGH 191AA (Somatropin) in a research context?
A1: HGH 191AA (Somatropin) is a recombinant, 191–amino acid human growth hormone identical to endogenous pituitary GH, used in laboratory models to study GH receptor signaling, IGF-1 regulation, and related endocrine pathways.
Q2: How is Somatropin different from other growth hormone–related peptides?
A2: Somatropin replicates the full 191–amino acid sequence of natural human GH, whereas many GH secretagogues or analogues act indirectly by stimulating GH release or modifying specific domains of the hormone or receptor.
Q3: What types of experiments typically use HGH 191AA?
A3: It is commonly used in receptor-binding studies, GH–IGF-1 axis investigations, metabolic and tissue-growth models, and as a standard in bioassays and immunoassays that quantify growth hormone activity.
Q4: Is HGH 191AA (Somatropin) intended for performance enhancement or therapeutic use?
A4: No. Research-grade Somatropin is intended solely for scientific investigation by qualified professionals. It is not approved or marketed for performance enhancement, bodybuilding, or any therapeutic use in humans or animals.
Q5: Who should handle HGH 191AA in the lab?
A5: Only trained personnel working in appropriately equipped laboratories and following institutional and regulatory safety guidelines should handle HGH 191AA.
