Personally I would use 500 iu every 3-4 days hCG. When I use to use an strong oral in the beginning I would have stalled gains in the cycle when I dropped the oral unless I replaced it with something. I would do something like this.
1-12 Sustanon 500 mg
1-4 Anadrol 50mg/d
9-12 Anavar 50 mg/d
The 4 week break without the oral will help your liver but you will have a brief stall. Then gains will take off again and be lean and hard. Tighten the diet the last 6 weeks and you will do really well.
