Turns out that even by using HGH, you are unlikely to exceed your genetic potential height.
The only use for it really is GH deficient people. Most teens (99% of all of you) are not GH deficient so it seems to be rather useless for height.
A 5-year analysis of GH treatment in children with IGHD, MPHD, SGA, or ISS showed significant height SDS gains (1.6–2.1), but outcomes approached—not exceeded—genetic height potential (defined as mid-parental target height), with corrected HSDS improving toward the target

Meta-analyses for SGA (4 RCTs, 391 kids) and ISS (10 studies, including 3 RCTs) found modest adult height gains (~4–5.7 cm over controls), but these
reduce deficits rather than surpass genetic predictions; response is variable and smaller than in GH-deficient cases, with no high-quality evidence for exceeding potential in non-deficient kids.

Also clinical guidelines confirm that in healthy children with normal GH levels, exogenous HGH does not boost final height beyond genetics and risks side effects like accelerated bone maturation.

Those jesters on tiktok didn't take hgh whilst it was being gatekept, they're just trying to scam you into buying their shitty course. Realistically, HGH is useless unless you have a GH deficiency which is unlikely.
