Here's the layout of my cycle.

Stats

Weight - 85kg
Height - 178cm
BF% - 15%

Week 1 - 4 Dianabol 20mg ED
Week 1 - 12 Test E 250mg x 2 EW (Tuesday/Saturday)
Week 1 - 12 HCG 300 iu x 2 EW (Wednesday/Sunday)
Week 1 - 12 Aromasin 12.5mg ED


PCT
Week 15-18
Clomid 75/50/50/50
Nolavdex 40/20/20/20


Supplements
Week 1 - 12
NAC - 2000mg ED
Vitamin C - 1500mg ED
Vitamin D3 - 2500 iu EOD
Vitamin B12 - 2500mcg ED

A few questions...

1) Can I use my A.I at 12.5 mg up to week 12 and then perhaps taper the dose during the weeks leading up to PCT?
2) Likewise with HCG, should I run this up to PCT?
2) Is the NAC dosing enough?

Thanks.
