My analogy was to point out a difference in potency. I should have explained exactly what was going on in my head. The analogy makes more sense after I explain myself.
I have been taking MDMA all this time by the way. Unadulterated MDMA in my area is difficult to come by as the apparent standard dose here, mentioned to me by my dealer friends, is 0.3g. I wouldn't dare touch "molly" without testing it.
Anyways, let's say the typical MDMA has the so-called "84% purity". A 100mg dose would be 84mg of MDMA with 16mg of impurities. Let's say the new batch I received, which is also white and odourless, is "Walter White methampetamine" pure, so it has 99% purity. In this case from a 100mg dose I'd have 99mg of MDMA with 1mg of impurities.
I have what seems to be the same MDMA that feedmesauce has and my intention of this thread was to receive similar responses to his/hers, as I don't want to dose too low or too high.
