Are you talking erase pro? Because og erase can be taken as much as 3-4 caps a day , were erase pro is always one cap. Either way I doubt they will be good enough to combat estrogen sides from test. Since you already have it I would use it in pct. Start it a week or two after you start your serm and run it with daa. Or save it for after cycle and pct and run a natty stack with it and daa
