Sorry for being the wet blanket, but some of the people who frequent this forum appear to be less than knowledgeable about this stuff and reckless in their approach, so I feel the need to point this out:
Unskilled people without proper equipment trying to measure doses with RC chemicals can end in tragedy. I'm not talking about just a bad trip, some of this stuff can kill you. Some good advice from elsewhere:
"A notable feature of many research chemicals is their extreme potency, with many active in the low milligram, and even microgram range. The safety window for some of these drugs is also quite narrow, meaning that toxic doses are not far higher than the active doses. As a consequence, the risk of a severely toxic and even fatal overdose is significant for some research chemicals if appropriate care is not taken with measurement. It is therefore highly recommended that anyone handling research chemicals invests in appropriate sets of scales and volumetric equipment."
