Doing 45 minutes first thing in the morning EOD.

Current weight 200lbs,6 feet tall,12% BF,39 years old
Eating 3500 super clean calories a day/400 grams protein
Current cycle 400 mgs Test E/week,37.5mgs Proviron/day,.5mg a-dex eod
Third cycle,but first one doing test.

Goals to gain 10-12 lean lbs of muscle.
