Somatropin is recombinant human growth hormone (HGH): a single-chain protein of 191 amino acids with the same sequence as the growth hormone made by the pituitary gland. It is quantified in international units (IU) rather than by mass.

Important notice
This product is for laboratory and research use only. It is not for human or veterinary use. By ordering, you confirm it will be used only for in-vitro research.
Reconstitution required
This peptide ships freeze-dried and needs a diluent such as bacteriostatic water before use. Bacteriostatic water is sold separately.
Description
About HGH (Somatropin)
Somatropin is recombinant human growth hormone (HGH): a single-chain protein of 191 amino acids with the same sequence as the growth hormone made by the pituitary gland. It is quantified in international units (IU) rather than by mass.
Growth hormone acts through the growth hormone receptor, a cytokine-type receptor that signals mainly through the JAK2–STAT5 pathway. In the liver and other tissues, this signalling drives production of insulin-like growth factor 1 (IGF-1), which carries many of growth hormone’s downstream effects. Somatropin is used in laboratory research on receptor signalling, the GH/IGF-1 axis, and growth and metabolism in cell and animal models.
Strengths are listed in IU, so use the IU mode of the peptide calculator.
Form and storage
Supplied as a lyophilised (freeze-dried) powder in a sealed vial. Keep unopened vials cold, dry and out of direct light: refrigerated for short periods, frozen for longer storage. Our guide to storing lyophilised peptides summarises the published stability research.

Who tests it?
Where we hold a lab test report (LC-MS purity and identity) it's published in full, with the lab's own verification link. Other lots ship with the supplier's batch specification.

1Research use only
HGH (Somatropin) is supplied for in-vitro and laboratory research. It is not a medicine, food, supplement or cosmetic, and is not for human or veterinary use. Handle it under your institution's safety procedures, with suitable protective equipment, in a properly equipped laboratory.
2Lyophilised peptides in transit
Freeze-dried peptides travel as a dry solid in a sealed vial, which is far more robust than a solution. When the parcel arrives, move the vials to cold storage, away from light and moisture.
Frequently asked
Why does the vial look almost empty?
A few milligrams of freeze-dried peptide is a very small amount of solid. It often dries as a thin film or small cake on the base or wall of the vial, which is easy to miss. It dissolves once the vial is reconstituted.
Is bacteriostatic water included?
No. Diluent is sold separately, and the peptide calculator works out concentration and draw volume for the amount of water you add.
