Loose skin timeline after rapid recomposition is a function of how fast the underlying fat shifts - the HGH and TRT combination accelerates that shift so the skin adaptation has to catch up at the same pace the underlying structure changes. Most people find that 6-12 months of stable weight with active skin-tightening interventions (retinol topicals, peptides like GHK-Cu, resistance training maintaining muscle fullness) produces meaningful improvement. Surgical options make sense when there's excess skin that doesn't adapt despite all that - but the window for assessing whether it's needed realistically starts a year after hitting stable weight.
