Biotraxx Classic 1:1 - Is this ok to use?

Hello,
Any help on this would be much appreciated
I recently bought the below (Germany company) to start taking MMS and just wanted to confirm if this is a reputable brand/product... If anyone has any experience using this one?

It contains Sodium Chlorite at 25% and the HCl is 5%.... I know 22.4 Sodium Chlorite and 4% HCI is advised to use...

Is Sodium Chlorite at 25% ok to use?  Also, I have read on other threads that 4% HCI has to be used.  Can anyone advise how I diluter this down to 4% please?

Biotraxx CLASSIC 1:1 Set, 1x 100ml Hydrochloric Acid 5%, 1x 100ml Sodium Chlorite NaClO2 - Biotraxx-Shop Europe

Many thanks in advance,
James

I use it and have had no issues. This was the one recommended to me 2 years ago.

I've had the same experience as @Kendolo6. Great quality. My first order never arrived due to a wrong address. Once they got the correct address it arrived in Western Canada in less than a week. I thought the customer service was great. I bought mine through Amazon. I use CLO2's quick "dry method" 3 hour recipe to make my CDS. If I were to switch back to CLO2's "wet method" I would buy this product again. Some might consider the price a little high but I go by the old adage "you usually get what you pay for."
