I have 10 caps of 250mg crystal DNP, and 120 powder DNP caps. I was thinking of using up the 10 crystal for the first week, and then use the powder for the remainder of the cycle. From I have gathered from research, crystal DNP caps are approximately 75% actual DNP, while the powder is entirely DNP. So, as long as I keep that in mind when dosing, I assume I should be able to make the transition. Is there some reason why this should not be done?
