just wondering if there is anyway to know if winny has gone bad... have had it about a year maybe a little longer. its been in my house in a cabinet. wondering because for a week or so prior i used winny pills EOD and was feeling increased strength. started injecting this stuff that i had about a week ago but not noticing the strength like i did before??? ......do i need to use more of the injectable than of the pills to get the same effect?
