Check the anabolics section, lots of andros logs. 800 mg of 1 andro is a hefty dose. You could see great benefit with half that dose. More does not always = better. Not to mention you will want a test base to keep lethargy at bay and keep libido. 4 andro and epi are both solid choices.
Generally speaking it takes up to 3 wks for andros to kick in for many users. I would run the andros for 6-8 wks. Start dosing at 300-400 and increase dosage as necessary.
Although andros are not active, they still cause suppression. Be sure to have pct lined up.
Just my two cents.
