The former two will be run at 100/mg day, but the question is the var dose.

My main aim with regards to adding the var in is more strength gain. Cost aside, will I see much more keepable strength gain from 100mg/day than 50mg/day?

Now on variation, will 100mg/day for 6 weeks be better than 50mg/day for 8?

Remember, more strength is what i'm after here. I will be cutting a very small amount of bodyfat along the way, but nothing drastic so calories will be maintenance.
