I do not measure it but it is stronger than just simple Miracle-Mineral-Supplement judging by its color..
I always take it with ample grape/apple juice with zero vitamin C..never with jut plain distilled water.And the smell is strong too..
The important thing is not to overdo it..
Also DMSO 50% means it is 50% DMSO and 50% water..
Will be getting DMSO 70% and we will see-I will start with a reduce amount of Miracle-Mineral-Supplement for starters..
