it kind of depends on your cycle as well. what are you coming off of and how long was the cycle. i usually find i can restore my balls by jump starting things at the end of 8 wk cycle with 2500iu twice a week for two weeks. a much longer cycle i would ofc increase to the last 3 or 4 wks. some choose to run it the last half of their cycle and some run it as soon as their nads start to shrink. different people have diff results.
anyways back to my original point, what was the cycle?
