sorry i misread that i thought you ON.

regardless, .5 caber twice a wk is common and typically is enough. if youre sensitive to gyno you could increase that to three times or eod. i believe the half life is 5-6days. there are on cycle protocols for letro outlined on this site. do a quick search, shouldn't have any trouble finding them.

but start out small and monitor. then increase accordingly. very difficult to say how youre going to react until youre on and able to monitor. past exp can provide some insight. what did you do last cycle?
