GH1
GH1 growth hormone — the molecular target that 1 compounds in the wiki act on.
In one line: The gene for growth hormone itself — the body's build-repair-and-lean hormone.
GH1 is the gene that makes growth hormone, which drives tissue repair, fat-burning, and (indirectly) muscle growth. Peptides like the "fragment" AOD-9604 are pieces of this hormone designed to keep just the fat-burning part without the muscle or blood-sugar effects.
Growth hormone is powerful but double-edged: helpful for genuine deficiency, but misused for physique it causes insulin resistance, swelling, and organ growth. More isn't automatically better.
