The common rumor is that the crystal is about 80%-90% due to the slight hydration as opposed to the powder.
its been a common misconception that "D's" DNP was powder and not crystal but if you have ever ordered from him he clearly states that he uses crystal.
Here is copy and past from his E-mail
"ABOUT THE CAPSULES:
The capsules I make are 250mg of lab-grade crystal (sodium dinitrophenolate), not industrial powder. After adding the 250mg of DNP, the rest of the capsule is filled with a mixture of antioxidants and amino acids (no drugs, stimulants, or herbs, just stuff that's healthy). I use Trimethyl Glyceine (
http://en.wikipedia.org/wiki/Trimethylglycine#Nutritional_supplement),
L-carnitine (
http://en.wikipedia.org/wiki/Carnitine#Role_in_fatty_acid_metabolism), and
Sulbutiamine (a form of Vitamin B;
http://en.wikipedia.org/wiki/Sulbutiamine#Therapeutic_uses).
L-Carnitine also helps reduce the incidence of peripheral neuropathy (pins and needles sensations), which is rare and not critical to health, but annoys some users who experience it.
I've also added DMAE, which will reduce the unpleasant side effects by a LOT. DMAE is also an antioxidant. Adding DMAE helps you feel less of the negative effects from DNP, even through the DNP is the exact same type and dose as always. Simply put, with DMAE, it'll feel like you're using less of the stuff, but without actually compromising the dose at all.
Crystal is more expensive, but DNP is a powerful material and must be manufactured with precision and experience; researching with DNP is not the time to search around for "bargain basement" third-world sources. It is worth it, I believe, to spend for top-grade crystalline DNP made in a clean laboratory, rather than industrial-grade powder. The lab that supplies me sells to nobody else; you simply will not find this grade of clean, fresh custom-produced material from any other source."
EA's new DNP is proving to be equally as effective as any other sources out there MG for MG and it cokes in 50 mg tabs so you can easily adjust the dose for you needs rather than be stuck at 250 or 500
