HCL Activator for CDH

I purchased HCL from www.mmsforhealth.com . When I was looking at the CDH instructions, it says to use 4% HCL and 22.4% Sodium Chlorite solution - but what I have is 5% HCL and 22.4% Sodium Chlorite solutions. Is the 5% HCL OK or do I need to purchase 4% HCL? If so, would who would you recommend?

Also, is there a recommendation as to how to measure quantities from dropper bottles and distilled water to make the correct concentration?

I answered some of your questions here .

It is easy to make 4% HCL from your 5% and you should if you are going to make CDH according to the original McRae-Lackney recipe.

Use the fourth calculator changing units to Percentage (%) at endmemo.com/bio/dilution.php

Droppers are notoriously unreliable to accurately dispense liquids. I have had droppers that varied 100% between two of them. You can calibrate your dropper using a 1 ml syringe and even use a 1 ml syringe to dispense drops. Using a standard of 24 drops/ml of solution, each drop would be 0.042 ml. If you use the standard of 20 drops/ml, then each drop is 0.050 ml. The latter is 20% larger than the former, meaning your dose will be 20% stronger. In the past Jim used 24 drops/ml, but may have changed to 20 drops/ml today.
