I have bought 50grams of DMI from http://www.bulkactives.com/ to add to my RU-topical. Costs about $32 for 50grams. It's very expensice since 50grams will be a little less then 50ml meaning less then 50 applications. (I'm planning on using 1 ml DMI per application ) Does anybody know of a cheaper place to get DMI. El-Duterino, you use DMI as well. Where do you buy yours from?
