i was gunna answer this then i reliezed i had no idea.lol (its kind of early in the morning) definatly is a good question though. i would say it depends on how effective the product is, if it dramtically increases test levels then when you go off of it the test levels drop then im sure youll notice a differance, but if your test levels are only increase by a small percentage then maybe you wont relieze any differances. i definatly have to get my test levels calculated one day it would be a cool thing to know
