I was shooting mega loads while on dbol and test until around week 8, my boys started to shrink after week 6...by week 10, I was just shooting enough to think I was having an orgasm....dbol does suppress test quite abit, so I wouldn't be surprised if after week 5 or 6 you notice a difference.....I know one of the guys includes clomid to keep his loads full! Ask around, I can't remember his handle....
Once you recoupe after PCT everything should go back to normal, however, I've found that you should run a very aggressive PCT which should include nolva and clomid and HCG....you may not need HCG for a dbol only cycle.....but I'm no longer taking any chances....
