Forgot to say how much to take each time. Normally about half a glass or 100-120 ml will be okay each time.
The F protocol shouldn’t be taken on an empty stomach as it is pretty strong for beginners.
CDS should be kept in dark coloured bottle as it’s sensitive to light and heat. The Oxygen would leak and dissipate very quickly. I have special bottles for the ready made CDS at 3000 ppm (parts per million) and a ready to drink bottle of 1Litre with 20 ml of CDS added.
This CDS will help to save lives in times of crisis when doctors and hospitals weren’t available.
