Well, I've never done it but don't see why it wouldn't work in 2%ba and 7 %bb. Use the powder calc in the lab conversion forum, enter in the info and it gives you the porportions of each. You migth want to do a search over there, I think I remember seeing a recipe that was a little different using PEG I beleive. Mind if I ask why your injecting it and not adding it to PG and drinking it?
