I have recently acquired 50mg of PURE Fentanyl Powder Hcl. I would like to mix this with water so that I can take it buccally. I know how dangerous this stuff is and I have to be EXTREMELY safe (gloves, masks, etc) Now I need to know how much water I need to mix with the 50mg of fentanyl to give me about 200mcgs per 1ml of solution. I'm terrible at math! Thanks for any help!
