Consumption of Aminos and Carbs before exercise is better for muscle growth.

In a study conducted at the University Of Texas,  scientists tested the results of eating Amino Acids and Carbohydrates immediately before and immediately after exercise and the anabolic response. The study showed that those who consumed aminos and carbs immediately before greatly increased the amount of aminos in the blood during exercise and for up to an hour after exercise. In addition, protein synthesis was greater for those who consumed the Amino's and Carbohydrates immediately before exercise. OUR CONCLUSION: Take your protein before you exercise. STUDY CONCERNS: Sample size was only 6, very small and more studies with a bigger sample size is needed to fully prove such a claim.

Lack of physical activity and a lazy father or male guardian is likely cause of child obesity. 

Scientists at the School of Human Movement Studies, The University of Queensland, Brisbane, Queensland, Australia studied the effects of physical activity on childhood obesity. The study found that obese children were far less physically active and were less likely to engage in community organizations that were physically active. In addition, the obese children were less likely to report their father or male guardian as physically active. OUR CONCLUSION: Get your child involved with physically active community programs in order to help them become healthy. In Addition, fathers need to get more physically active with their children if they are obese. study authors: Trost SG, Kerr LM, Ward DS, Pate RR.

Andro has no effect on body composition, mood, or exercise performance.

Subjects who were given 100 mg of 19-nor-4-androstene-3 17-dione (N-dione) and 56 mg of 19-nor-4-androstene-3,17-diol (N-diol; 156 mg total norsteroid per day), or a placebo showed no affect in body composition, mood or exercise according to a study conducted at University of Nebraska, Human Performance Laboratory, Kearney, NE 68849, USA.
