Purchasing Human Growth Hormone (HGH) depends entirely on your location, its intended use (medical vs. research), and whether you have a prescription. Generally, you cannot legally buy HGH for personal use without a doctor's order. In most countries, HGH is a strictly regulated substance.

: Real HGH (somatropin) is a prescription-only medicine and must be prescribed by a licensed healthcare provider.

: The FDA and similar bodies only approve HGH for specific medical conditions, such as growth hormone deficiency, Turner syndrome, or chronic renal failure.

For laboratories or medical facilities, HGH is available through chemical suppliers.
