yes. Weigh your doses carefully. You should either be working with a very accurate scale (a scale that reads +/- .1mg), or weighing out a larger amount and then using liquid measurements to weigh out each individual dose. Also, start low for your first time. You could be ultra sensitive to the chemical, have an allergy to it, or you just may find out you really hate the way it makes you feel. Taking a big dose of any DOx is quite the commitment. You could be in for one hell of a long ride if you dose too big. I'd recommend starting somewhere between 1 and 2mg. You could even start lower if you want to be extra cautious. DOC is a wonderful substance, in my opinion, but not everyone would agree. I think the best part of DOC is the afterglow you acheive once the peak effects start subsiding. This afterglow stage lasts well into the next day, and is very peaceful and serene (for me, anyways). Good luck
