Making a Copper Sulfate Supplement: 3 x 1/8th teaspoons in 2 oz. water, makes 1 mg per drop

Making your own copper sulfate solution of 1 mg contained copper per drop is very easy. Just measure out the blue copper sulfate crystals and the water. You can buy blue copper sulfate crystals at amazon or any large internet retailer. I look for 99% or 99.9% pure.

Ingredients:
1 teaspoon copper sulfate crystals.
5 oz. of water.

Personally, I make a 2/5ths teaspoon into in a 2 oz. dropper bottle, as follows:
3 x 1/8 teaspoons, plus a quarter of a final 1/8th teaspoon.

3/8 = .37
.25 x 1/8 = .03
.37 + .03 = .4 = 40% = 2/5ths of a teaspoon.
