HGH

What it is: Human Growth Hormone — a polypeptide produced by your pituitary that drives growth, repair, and metabolism. Production peaks in youth and falls steadily after age 30.

What it does: You can expect increased lean muscle mass, dramatic fat loss (especially visceral), tighter skin, deeper sleep, faster injury recovery, denser bones, stronger libido, and sharper cognition.

How it's used: Daily subcutaneous injection, typically before bed or post-workout, at 2-4 IU daily.
