Nutritional Supplement Reviews by Real People Like You

I am 14 years old, 5'11", and weigh 195 lbs. I play varsity football for my high school and throw shot put. About 3 months ago I started taking creatine monohydrate and tribulus terrestris supplements. I was told that people under 16 should never take creatine. However, I feel that due to my size and development, I might be an exception. Someone please tell me if there are any dangers in taking these supplements too early.

Question expanded by another reader.
Should tribulus be used by anyone under the age of 18?
