Well, I was googling the wrong thing then because I spent some time searching around and I couldn't find anything helpful.
I don't get why everyone must get so insane about the fact that it's on google. I'm sure most of the things on here you'd be able to find on google if you just searched around a lot.
The point of posting this was to find something easier and faster, because I didn't have all the time in the world.
And sorry, I worded that wrong. It's not that I don't know how much I'm getting, it's that I was unsure of how much to purchase.
And thank you.
In future, just put in "*substancename* Dosage" in Google and you'll almost certainly find a bunch of useful links unless you're looking at a novel research chemical with little information available.

Also, just to clarify, generally when referring to hallucinogens we classify them into three groups, Psychedelics, Dissociatives and Deliriants.
Psychedelics include such things as: LSD, Mushrooms, Mescaline, DMT, 2C-*, etc
Dissociatives include:
Ketamine, DXM, PCP, Nitrous, Salvia Divinorum
Deliriants include: Nutmeg, Diphenhydramine, Tobacco (Large doses), Datura
However, while this is the forum area for "Psychedelic Drugs", discussion of dissociatives, deliriants - and even some entactogens is allowed.
