It's my understanding this is one of the purest 100mg nicotines available. The reviews say that it doesn't have the "peppery" taste found especially when you go 18mg and up. I am growing to like custards and creamier blends but not found of the pepper taste I'm getting from the nic. Wonder why more producers aren't using this? May be more than I think but I would really love to know who they are?
