What is HGH (Human Growth Hormone)?

Human Growth Hormone (HGH), also known as Somatropin, is a single-chain 191-amino-acid polypeptide produced via recombinant DNA technology in E. coli expression systems. It is structurally and biologically identical to growth hormone secreted by the anterior pituitary gland.

In research settings, HGH is studied for its role in activating the growth hormone receptor (GHR) and stimulating hepatic and peripheral production of insulin-like growth factor 1 (IGF-1). Downstream research applications span lipid metabolism, protein synthesis, cellular regeneration, and age-related endocrine studies.

Each batch is independently verified for purity, identity, and endotoxin levels, with a certificate of analysis provided for every lot.

HGH (Human Growth Hormone) reconstitution reference

Reconstitute with bacteriostatic water. The table shows the concentration and syringe volume produced by common dilutions of a 10mg vial, for reference when preparing research stock solutions.

Storage & handling

Before reconstitution
Store lyophilised at −20 °C, protected from light. Stable for 24 months or longer in the sealed vial.
After reconstitution
Store at 2–8 °C and use within 28 days. Avoid repeated freeze-thaw cycles; aliquot where possible.
