Yes, and the claim that there are no safe DIY formula instructions is an assertion of fact. The question of whether incorrectly produced formula could be dangerous was never at issue.
Well we’ve demonstrated that the requirements are very strict, that manufacture standards are precise and include steps not available to laypeople such as ph testing, and that the outcome of a bad creation is potentially fatal. So it seems reasonable to say it follows that there are no safe DIY formula instructions because DIY implies lack of expertise which is required to understand the points listed above.
