Now, we all know the affects of Test (natty or synthetic) on body composition, hunger, libido and the likes. I am just curious if anyone knows of any studies done on Test Levels and learning abilities. Increased Test = increased memorization?? Increased Test = increased understanding?? Increased Test = concentration during studies (instead of workouts)?? Just something that popped in my head. I mean test affects almost every aspect of the male body. So how about how the mind works?? How the neurons and nerves work in the brain when you have a excess amount of test in your body. Does anyone have any info or know of any sites, studies or research??
