i would re-arrange it this way.
1-16 Deca at 500mg/wk
1-16 EQ at 400mg/wk
1-17 Test E 600mg/wk
17-20 Tren A 100Mg/EOD
17-20 Test P 100Mg/EOD
17-20 Masteron 100mg/EOD
3-20 HCG 500IU's every Sunday
3-20 letrozole 1.25E3d
21-25 Clomid 100mg/day
Notes on edited cycle:
* More than 2 weeks of clomid are needed for such cycle.
* long esters (deca, eq and test e) are all gonna be out of ur system by end of week 20
* all of the short acting steroids will also be out of ur body by end of week 20 also.
this way, you can have an exact perfect point on where to start your PCT.
