Gotta know and all info is appreciated....I've found vendors who sell the 555 flavor to add to my unflavored liquid, but the vendors don't appear to have any tips on mixing. If I want to make a 30ml bottle of 555, how much flavoring would be comparable to the flavored I would normally buy? I'd suspect the nic mg would play a factor (36 for me), but I don't know how far a 5 ml or 15 ml bottle of flavor will get me. Is it potent? Would I be looking at a 50/50 mix? Ballpark figures is all I'm looking for, but I'm at a loss for a start. Anyone with knowledge please post. Let me know who you buy it from and how potent it is, as I assume the different vendors probably vary potency. Thanks, all .
