Not sure if that period is too short, depends on your bf% 3 weeks back. 3-5 kg lean muscle while being dry as fuck? That's -IMO- not the smartest strategy to follow, but a good cycle does magic, like 300-500mg of test e, combined with some extra calls.
well, i'd estimate it that i went from 9% to 6% in those 3 weeks
before when i lost fat while gaining muscle i went from 10% to 8% while gaining 3 pounds of scale weight so my muscle gain to fat-loss was roughly 6 muscle pounds gained and 3 fat pounds lost over a 6 week period
the funny thing is, i'm even leaner now than i was in those pics which were taken last week
i want to get down to 4% and the way it's going now i'll be there in less than 2 weeks

You look great bro.....super lean!!!! Don't get TOO lean if ya not doing a show?
thanks man
and can i ask why i shouldn't get leaner in your opinion?
i'm thinking that if i get as lean as i want and can function well then it's not a problem
supposedly essential bodyfat for males is 3% and i don't want to go under 4%
