One of the most common questions asked about HGH is whether it can make users grow taller. Between the ages of about 12 and 18, your body is still growing. During this time, the administration of HGH can help you add inches to your height. As such, HGH is an essential part of therapy for children who have growth disorders such as dwarfism. However, between 18 and 21 years old, growth plates on your bones fuse together and essentially “lock” your height. Administering HGH may cause individual bones in your body to thicken, but it will not lengthen them.
One last point: Because steroids have all these side effects, a lot of abusers will then take other drugs to offset the effect—steroid abuse causes you to grow man-boobs, so people take another drug to mitigate those side effects. Guys who take steroids often also take augmenting drugs to decrease estrogen production or to improve athletic performance even further, like human growth hormone, insulin-like growth factor 1, insulin, erythropoietin, stimulants, diuretics, levothyroxine, and/or gamma-hydroxybutyrate, according to the study in FP Essentials . That means on top of all these side effects of steroids, most abusers are also looking at a whole separate list of effects from their peripheral drug habits.
