steroids can burn fat but not directly mainly due to the other factors. increased muscle mass raises you metabolic rate burning fat , eating the extra calories from protien cuases a thermogenic effect. winstrol ,anavar and primo have been shown to also upregulate a recpetors and cuase some kind of a fat loss effect but its not really sufficent to burn alot of fat.
only things that gonna burn fat is busting your ass in the gym and doing cardio witha stricter diet.
if your gonna do the chemical fat diet then you could go with t-4 clen and ephedrine but the bounce is bad enough to where alot of people end up fatter when they come off then when they even started a few months afterwards.
blue twisted mentioned a stack with eq i agree 100% something like this
primo 600mg a week 12 weeks
eq 400mg a week 12 weeks
winstrol at 50-100mg a day 6-8 weeks
if your diet is in check and the protien and caloric needs are meet but not over done you should be able to even build some muscle while your burning fat but its a tough call some guys dont build at all when they get down into the 1200-1800 calorie range a day and some guys can build a little lean muscle.
primo from what i have seen and read is THE ONLY steroid that can build muscle on a low calorie diet it is amazing stuff
as far as the nipples. the stack above should not cuase any problems but the eq can aromatize so be sure to have some arimidex or letro on hand along with nolvadex to treat the swollen breast tissue. i would start them before the cycle or as soon as you can just to get in under control. once it flares up even the mildest steroids can cuase it to flare up again later . due to the fact it took you 3 cycles to get the growth started and developed so its already their . so when a steroid upsets it it can be just a matter of days for it to come back. 1# prority get your anti estrogens 2# get your diet planned out 3#get your steroid cycles planned 4# get your post cycle planned for recovery 5# buy all that you need gear, anti estrogens,pins, then write down your log and besure to have everything you need. i would not start your next cycle untill you have a few bottles of nolvadex,arimdex,clomid and maybe even letro if you cant afford the anti estrogens and pct drugs then you cant afford to cycle roids simple as that
i'm saying it becuase you got burning nips and didnt treat it last cycle means you might not have been prepared for the side effects. i'm trying to help ya as a friend bro not bust ya chops
good luck with it man planning is key
