Dosing and capping DNP is messy, but it is relatively easy.
Get a size 00 cap-m-kwik. (after using it for DNP you will not be able to cap anything else with it) Fill it with empty capsule halves.
Weigh out EXACTLY 10 grams of dry DNP powder.......make sure it is completely dry, or your dosing will be off.
Then weigh out 10 grams of cornstarch.
Mix the DNP powder, and cornstarch together. Make sure to break up all the clumps.
I like to force my DNP cornstarch mixture through one of those really small metal strainers (you can get one at any super market, or dept. store) that way I know all the clumps are broken up. Then put the powder into a container that has a tight sealing lid. Shake the powder for a while to get it well mixed. Then dump it into your cap-m-kwik, and level it into the capsules. You have to pack them really good to get all the powder into them, but it does all fit.(it helps if you get one of those cap-m-kwik tampers) Then put the top halves on the caps, and then take each capsule and compress it tightly by hand, and wipe it with a paper towel. This will give you 50 capsules at 200mg each.
I should add that you need to wear at least two layers of rubber gloves, to avoid staining your hands yellow.
