I spoke with a couple of vendors reps. They suggested buying Bac when ordering. I then asked about buying bac separately. They said the shipping cost makes it not worth it. 10 vials of 30ml bac @$30 costs $50 to ship
Also, although, yes, technically there IS a 2 year expiry date on every bottle, your Bac in general will last much longer when stored appropriately according to the manufacturer's direction. If my math is correct, I will run out of bac approximately the same time I run out of peptides.
Panic buying is not the worst thing to do. Js.
