I know that Biotest and t-mag are mainly geared towards body building but are there any biotest supplements that are worth taking to improve sports performance? I play lacrosse and I know that how big you are does not translate into being a better player, not even shooting faster. I am 17 years old, 6’4 and appx. 200lbs. My diet is good, I get enough protein and good fats as well as lots of complex carbs. I lift two times a week using multi-joint movements as my staples. I do more turning rope and running than anything else. Would any biotest supplements aid me in getting faster or in helping my endurance? Thanks.
