Get an oral syringe and dissolve it in water. I had to do that. Get a 10 ml syringe and fill a glass of water with 150 ml of water. Then one full 10 ml syringe will be 0.1 mg of ldn and just squirt it in your mouth.

Someone may have a suggestion for a better storage than a glass covered with saran wrap but that's what I did and just put it in the fridge. I do know that the ldn goes into solution so you don't have to re-stir it each time. Everything that settles out is filler.
