I need an educated answer as to how long the potencyl lasts after it's mixed. I probably take smaller does than most on here. I mix the bac water at the 100 line into the water and adminiter 20 per day so that lasts me for 5 days. I work out tues, wed, fri and sat and i was told to do it on workout days only. (I prefer m-f though). I know have increased to the 25 line per day (believe it or not I get good results) so a vial lasts 4 days now. SO, by me mixing it on tues and the first dose is tues and doing it on wed, thur and fri and starting a new vial on sat, is this too long or should I just do m-f?? Because after sat it sits in the fridge untouched and I don't use it again till tues. Like I say, would m-f just be better? Also, I use it pre-workout for now. Once my job hours start i'm going to have to do it first thing in the morning. Please help folks. Thanks.
