HGH: Research Background
Mechanism of Action: Recombinant human growth hormone (somatropin) is a 191-amino acid polypeptide that binds to GH receptors, activating the JAK2-STAT5 signalling pathway and stimulating IGF-1 production. Promotes lipolysis, protein synthesis, and bone mineral deposition.
Research Applications: IGF-1 axis regulation, body composition research (lean mass accretion, fat mobilisation), bone mineral density, GH deficiency models, metabolic rate research.
Storage & Reconstitution
Storage: Store lyophilized powder at -20°C. After reconstitution, store at 4°C and use within 14 days. Do not freeze reconstituted solution.
Reconstitution Protocol: Add 1–2ml bacteriostatic water per vial. Inject along vial wall, swirl gently. Do not shake.
Quality Verification
Every QSC HGH batch undergoes: HPLC purity analysis (≥99% specification) · Mass spectrometry molecular verification · Impurity profiling · Batch traceability to published COA.
Certificates of Analysis are published on the product page and independently verifiable via the Janoshik testing portal.
