I start week 10 of my test e only 500 on Sunday and I have to open another vial. I was thinking of upping the dose to use the vial so there was nine left except the other unopened vial I will have left over. I have read in some places this isn't a good idea and some other say to for it but I wanted to ask in my own thread and see. I'm happy with my gains so far and if I'm told not to its fine but if it isn't a bad idea and go for it then I'm all over it. Just getting input. If not ill have some to start next cycle. One will just be opened.
