Would it loose it effect ? Help Guys!!!!! 2017-04-05 at 11:14 AM #11545 crownvicboyParticipant No, it will not loose it’s effect. It will be difficult to inject a cold oil…but that is something that you will figure out on ya own. Unless you plan NOT to be using ampoules of A.S. for at least 2 months, then refridgeration is not neccassary. take care; CVB 2017-04-05 at 11:57 AM #11546 swim4lifeParticipant CVB.
