HGH 191AA

Summary

HGH 191AA is somatropin: full-sequence recombinant human growth hormone, with its 191 amino acids identical to those of the endogenous molecule. Unlike secretagogues, it supplies the hormone directly instead of stimulating the pituitary to release it.

What is it researched for?

• • GH / IGF-1 axis and somatotropic signaling
• • Body composition and protein turnover
• • Lipid and glucose metabolism
• • Tissue recovery and repair

Cycle and break

Mechanism of action

Somatropin — complete 191AA sequence

Produced by recombinant DNA technology, it reproduces the 191-amino-acid chain of human GH. The 191AA designation distinguishes it from 192-amino-acid variants, which carry an extra methionine.

GH receptor pathway

It binds to the GH receptor and activates the JAK2/STAT5 cascade, which induces hepatic production of IGF-1, the main mediator of its peripheral effects.

Measured in international units

It is quantified in IU rather than milligrams, the standard convention for protein hormones. For reference, 1 mg is approximately equivalent to 3 IU.

Scientific evidence

Well-characterized molecule: Recombinant somatropin is one of the best-described therapeutic proteins in modern pharmacology, in clinical use since the 1980s.

GH / IGF-1 axis: The literature documents in detail the dose-response relationship between exogenous GH and circulating IGF-1 levels.
