stop the gear and take the AB's. antibiotics will kill certain foreign organisms that actually live in us to help us survive. some of these same organisms also serve a purpose of handling anabolics/androgenics, and w/out them you will reduce the effectiveness of your gear. this is not to say that your gear will be useless but certainly less effective. dont worry bro, ramp down from the gear then complete your AB''s until they are done and then continue to grow. setbacks happen to everyone, you just have to learn how to deal with them physically and mentally. taking off from the gear temporarily will not hurt your gains, just keep training hard. get well.
