Somatropin HGH (Utitropin) 100 IU

Utitropin (Somatropin) 100 IU is Utinon's recombinant growth hormone, supplied as a single 10 ml vial. The vial holds 33.3 mg of somatropin, equivalent to 100 IU, in one multi-dose container rather than a multi-vial kit. Each vial is sealed in a printed carton with a scratch-off authenticity code.

What Utitropin 100IU Is

Somatropin is recombinant human growth hormone produced by rDNA technology, identical in sequence to the pituitary hormone. It binds the growth hormone receptor and triggers insulin-like growth factor 1 production in the liver. A single 10 ml vial contains 100 IU, or 33.3 mg. The one-vial format removes the reconstitution step across a ten-vial kit.

The History of HGH

Recombinant somatropin was first approved in 1985, replacing pituitary-derived hormone after safety concerns about contaminated extracts. It became the standard treatment for growth hormone deficiency in children and adults. The multi-dose vial format followed as a way to reduce handling, and the single 100 IU vial is a later convenience presentation for research use.

How It Works

Somatropin binds the growth hormone receptor on hepatocytes and other tissues, stimulating insulin-like growth factor 1 release and direct metabolic effects. It increases protein synthesis, lipolysis and bone turnover. The hormone is cleared partly by the liver and partly by the kidney, with a half-life of a few hours, but the insulin-like growth factor 1 response lasts much longer. Because it is a protein, it must be handled carefully once reconstituted.

What the Research Shows

• Recombinant somatropin replaced pituitary-derived hormone in 1985.
• Its effects on growth, lean mass and lipolysis are well documented.
• Insulin-like growth factor 1 is the main downstream mediator.
• Handling and storage after reconstitution affect stability and potency.

Research Context

Somatropin is the reference growth hormone in endocrine research. Studies use it to model the growth hormone / insulin-like growth factor 1 axis and to compare newer secretagogues against the exogenous hormone. The single 100 IU vial is a practical format for that work because it reduces the number of containers and the handling steps. Stability after reconstitution is the main variable to control.

Strength, Pack and Authentication

The vial contains 100 IU (33.3 mg) of somatropin in 10 ml, and the pack is a single-container kit rather than a ten-vial set. The vial is sealed with a flip-off cap and boxed in a printed carton that states the compound, strength and volume. A scratch-off security code inside the box links the pack to Utinon's manufacturing records.
