I have two kinds of capsules, the difference is that one is dark brown, and the other is brown-yellowish...
Cap #1
If you watch, powder is brown, the notebook is yellow because powder made it, this yellow is very hard on the notebook..
Caps # 2
powder is brown-yellowish...
both have dnp - dinitrophenol - , at least that i think...
i think the second one has more dnp - dinitrophenol - that the first one...
What do you think about it=?
