GH-191 is a recombinant 191-amino-acid polypeptide corresponding in sequence to human growth hormone. Supplied lyophilised at 24 international units for laboratory research use.

About the compound

What HGH (GH-191) is.

GH-191 is somatropin — growth hormone built to the full 191-amino-acid sequence rather than a compound that signals the body to release its own. Research on growth hormone spans cell growth, protein synthesis and the production of IGF-1, which mediates many of its measured effects. Laboratory use only.

Research

What HGH (GH-191) has been studied for.

A plain-language summary of the published work. Almost all of it is in cells and animals — where a study was done in people, it says so.

Full research entry

  1. 01

    The full-length sequence

    GH-191 is somatropin built to the complete 191-amino-acid sequence of human growth hormone, rather than a fragment or a compound that prompts release.

  2. 02

    IGF-1 production

    Research measures IGF-1 as the principal downstream marker of growth-hormone activity.

  3. 03

    Protein and tissue metabolism

    The literature spans protein synthesis, tissue growth and how the body handles fats and carbohydrates.

Sold for laboratory research use only. Not a drug, not a supplement, and not for human or veterinary use. Nothing above is a claim about what this compound does in people.
