Others purchase HGH products -- or products that claim to increase your body's own production of HGH -- in the form of pills and sprays. Companies that market these products on TV infomercials or online claim they turn back your body's biological clock, reducing fat, building muscle, restoring hair growth and color, strengthening the immune system, normalizing blood sugar , increasing energy and improving sex life, sleep quality, vision , and memory. However, the Federal Trade Commission has seen no reliable evidence to support the claim that these products have the same effects as prescription HGH, which is always given by injection. Taken orally, HGH is digested by the stomach before it can be absorbed into the body.
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.
