Hi
If i would like to shoot 500mg/week of sustanon in eod shots how i should proceed? Let say i open the ampule of 250mg/ml, ill inject half ml, now what to do with the remaining half ml? I draw the test into a new seringe and keep it for the next shot and when i inject just to change and put a new needle on that seringe?Would that be safe? I dont want to get an infection or something.
