GHR
GHR growth hormone receptor — the molecular target that 1 compounds in the wiki act on.
In one line: The receptor growth hormone plugs into to do its work.
GHR (the growth hormone receptor) is the dock that growth hormone lands on to trigger its effects — releasing fat, building tissue, and telling the liver to produce IGF-1 (a key muscle-growth signal). Injecting actual growth hormone works directly here, unlike the peptides that instead nudge your own pituitary to release more.
The direct approach is potent but carries the real risks of flooding the system: insulin resistance, swelling, and, because it's a growth signal, a tumour-growth caution.
