What the studies show
In children and adults with diagnosed deficiency, replacement restores growth and improves body composition and quality of life. This is the licensed indication and is not in dispute.
Several well-run randomised trials in people, pointing the same way. You can plan around this. It still says nothing about whether the effect is worth the side effects for you.

In context
Growth hormone is a 191-amino-acid protein, approved for decades to treat genuine growth-hormone deficiency in children and adults, where it works well. Sold as an anti-ageing or physique drug, its record is different: a meta-analysis of randomised trials in healthy older adults found it shifts about 2 kg of fat to lean tissue with no change in total weight, while significantly raising rates of swelling, joint pain, carpal tunnel syndrome and gynaecomastia. The authors concluded it cannot be recommended for that purpose.
Human growth hormone (somatropin) is approved (rx) for deficiency; anti-ageing use unlawful in the us. Legal status differs by country — see the regulation section or the jurisdiction pages.
