Somatropin (HGH / Human Growth Hormone) 50IU Snap Pen

Somatropin Snap Pen contains sequence-identical 191-amino-acid recombinant human growth hormone (rhGH) in a dual-chamber device. The peptide and bacteriostatic diluent are stored separately to help preserve stability; twist to snap the internal seal, gently invert to mix, prime, and dispense. Designed for laboratories and research institutions conducting GH/IGF-1 signaling, metabolism, and tissue-engineering studies. 

How It Works (Mechanistic Context for Experiments) 
GHR–JAK2–STAT5 Signaling - Somatropin binds the growth hormone receptor (GHR), activating JAK2 and downstream STAT5 (primarily STAT5b); STAT5 dimers translocate to the nucleus to regulate gene transcription.GH → IGF-1 Axis - GH stimulates hepatic and local tissue production of IGF-1, which circulates bound to IGFBP-3/ALS and mediates many anabolic effects relevant to growth, protein synthesis, and metabolism.
Anabolism & Metabolism - In adult physiology, GH shows nitrogen-retaining, protein-synthetic effects (directly and via IGF-1) and interacts with lipid and glucose pathways—key readouts in metabolic and tissue models.
