oh and if you wanna make one bottle at a time at 200mcgs/ml then you just multiply 200 x 30(the volume of the bottle) which is 6,000mcgs = 6mg, so you weight out 6mg, dump it in the bottom of the dropper bottle, add the solution of alcohol/water up to the 30ml mark. and BOOM your all done and ready to go
if 200mcgs per 1ml is too much, then cut the overall dosage in half, use just 3mg, and this yields 100mcgs/ml
