6 wks is really the effective duration bro. Going beyond that isn't really positive. I guess u could run it maybe a week longer and up ur dose now to 450 or 500 that way u use the most of it but screw it if u have a little left over. I've got probably 5-6 vials of 1/4 full test, eq, deca, whatever sitting in the cabinet that I just need to throw out. Things just shake out that way man, no biggie.
