1 cubic centimeter = 1 mL
1 mL = 1 g
The above are temperature dependent but work well for normal laboratory or home use. The concentration of your stock solution is 19,430 mg/L. MB solubility is approx. 1 g per 25 mL of water, 65 mL of alcohol.
At maximum solubility the concentration is 40,000 mg/L so your stock solution is a little less than 50% by volume.
Dilutions can be calculated by ratio and proportion using this formula
M1*V1=M2*V2
where M1 is the mass or concentration of stock solution. M2 is the mass or concentration of target solution. V1 is the volume of stock solution required to make target solution.
V2 is the volume you want of the target solution. for example to make 100 mL of a 0. 1% solution
50*V1 = 0.1* 100 so
V1 = 10/50
V1 = 0. 2 mL or 0. 2 grams of the stock solution
I hope this help you understand how dilutions work. I do not know what concentrations you should injest. My example is just to show you how do make the dilutions.

hi Meera ; you can purchase MB at Script pharmacy in Calgary Alberta. I am sure you have compounding pharmacys in TO. Script made mine to the concentrarion I asked for! This should make it easier for you. Hope that helps. Flora

I use two drops in a shot glass of distilled or spring water.

I know it's way late, I guess you already have answer, but I see so many confusions about % of solution, so here it is for those still confused:
% = g/cc, what you have 1.943g/100cc = 0.019 =~ 2% solution.
To make 0.1%, add 19 x water to it.
But better way of using it is use what Bill said:
. just use 1 drop and consider it to be 20 drops of standard 0.1%.
. add 20oz water to it. Now your 20oz is equiv. to 20 drops.
. If you take 1 oz, you just took 1 drop,
take 2 oz, you just took 2 drops, etc...
Good luck.

I have tried 2 compounding pharmacies in Toronto- they say need prescription. If anyone has a compounding pharmacy that will make the 1% solution, I can send you money to buy for me....thnx

I just bought some from Amazon and received it in 1% 2oz for $10. US
