im pretty sure there is a Mod here that was also considering this... well see if he chimes in...
it needs to be monitored for sure... and im sure its been done by quite a few... im sure there are plenty of pro bb's that run it HIGH year long... that being said, they are not much of an example of healthy living anyways...
id figure out how much its worth to you, and how necessary it is for your goals... imo to be competitive in sports that are riddled with PED's, blasting and cruising is the way to go... but if you are just competing with the average joe next door trying to look good with your shirt off, seems a bit over the top to me...
