HGH - Human Growth Hormone Side Effects

Extended Belly
When used as a bodybuilding drug, HGH can cause a bodybuilder to have an extended belly if the drug is not used as directed. However, this defect is rare in users who take the drug as directed.

Carpal Tunnel Syndrome
Carpal tunnel syndrome is caused by a pinched nerve in the wrist. It can lead to loss of hand movement. HGH has been known to cause carpal tunnel syndrome in users who do not take the drug as directed.

Joint Pain
Because of its ability to cause growth in a person's body, some users report joint pain while taking HGH. This side effect is usually temporary.
