I haven't tried it on it's own, but I have Fluffernutter (peanut butter, marshmallow and bread.) It's what I'm
vaping right now.
The peanut flavor is accurate. I can't tell you how strong it is because the marshmallow mutes it a bit, which I like. I've had it for a month and the marshmallow is coming out more than it was at the beginning. As a result, I feel like I'm eating something with peanut in it rather than a spoonful of PB.
