I would guess it depends on the person. For me, anything that creeps up to 4 and above sets me off. Personally, I could handle a little bit more, but an entire double dose would be really pushing it. Again, thats for me. I cant speak for anyone else. Like I said earlier, I would still like to try it and see but no way am I blowing that much for something that makes me feel like a meth head with chicken pox.Eh, anything about 2g and up and it’s just gonna itch and tingle for me - how much worse could it get compared to 3.2g??
