Using Amps

[ToJuice,OrNotToJuice]

Ok guys I have amps that are like small vails, not glass break offs. I was wondering if there is any way that I can use like half of one and use the other half like three days later. I plan on splitting my 500mg of test and 300mg of deca into two injects over the week, the amps are 200deca/2ml and 250testE/2ml. thanks guys

how many mls in each amp?

does it have a rubber stopper?
if not keep it stored in a syringe.
only inject half
replace needle
inject other half later
