The mice were divided into four groups: 1) Exercise and mesterolone, an anabolic steroid (trade name Proviron) 2) Exercise and a placebo3) High and low carbohydrate diet 4) Mesterolone alone. After 30 days of diet and mesterolone maintenance, there was no significant difference between groups in body weight; however, there was a significant increase in body weight in the high-carbohydrate diet group (P = 0.005). There was a significant increase in plasma mesterolone in the exercise and low carbohydrate diet group, but there was no effect on the mesterolone plasma ratio or plasma levels, history of anabolic steroid use in sport and exercise.

Furthermore, neither mesterolone nor exercise supplementation can result in significant body weight gains. This diet-related increase in mesterolone levels may not be permanent, at least in obese rats, steroids in tablets muscle growth.
