No, there are some negative side effects in very small percentages of users. Less than 10 percent report one of the following: swelling of the hands and feet, wrist pain, overall joint pain, allergic reactions, water retention, and a very few state that existing tumors grew in size.
Obviously, carpel tunnel or serious allergic reactions indicate that you should leave GH alone. Hey, some people are allergic to steroids.....wouldn't that suck.?
Anyway, I have regularly used synthetic GH for years with nothing but good results. No way I stay big and lean and vascular and without a lot of wrinkles at age 53 with no GH.
