200mg is dose for horse  really do not try that it will not end up good.

Start with around 10-15mg max and then more once you feel confident. You really need .001 scale for this. Or if you have to use yours maybe weight .01g = 100mg and divide it by 7. You should get seven 14mg doses out of it. That is the best you can do or as I said buy new .001 scale something like thiswill do.

Also do not forget that vaporising technique is very important. If you don't get that right you will most definitely burn DMT and feel nothing. Make your self The machine or get GVG

Safe journeys
