any advise with the last three weeks?

weeks 1-10 sust 375mg ew
weeks 1-10 deca 150mg ew
weeks 1-6 dianabol 40mg ed
weeks 12-15 t3 taper up to 100mcg, durabol 50mg eod, winstrol 50mg ed

i.m 24, weigh 15 stone, been training since very young, wouldnt be able to say body fat but would say i'm average. eat anything and everything minimum 250grams protein a day but try to exceed 300g. try to limit to 2 shakes and rest solids for protein but will drink more on a day where i feel i have not reached 250g

my main goal with the three weeks is to lose as much fat as possible. the reason i am taken the winstrol is that i have been told that it works very well with t3 and gives satifactory results however it alone will not protect the muscle from the t3. which is why i have decided to add the durabol. i hope by leaving the two week gap it will give time for the bulkers to leave my system(or would three weeks be more effective?), before trying to lose the fat and definre the muscle. also by leaving the gap between the deca,sust and the durabol it will enable me to jump on to pct within a matter of days
