TweetI know drol makes me lathargic at high doses. And dbol maybe a little sluggish. My opinion as to why is that you grow so fast your body must have rest to grow. So your body is telling you to rest. I just eat as many calories as possible when on either try to get rest. I usually only run orals 4 to 8 weeks depending on dosage. So I just fight through the tiredness and enjoy the results.
