Prescription growth hormone is legal only when a doctor prescribes it for an approved medical condition. Federal law specifically bars distributing it for anti-aging, bodybuilding, or athletic use, with serious penalties. So when people ask for a legal alternative, they usually mean something they can buy without a prescription.
The honest answer has two parts. First, the habits that support your own natural growth hormone are free and legal: prioritize deep sleep, train with intensity, and keep body fat in a healthy range. These produce normal, short-lived pulses rather than large changes.
Second, dietary supplements marketed as HGH support are legal to buy, but they do not contain growth hormone and the evidence that they raise it is weak. If you choose one, consider it a minor addition, not a replacement for medical care. Pick a transparent, third-party tested product, and talk with a doctor first, particularly if you take medication.
