Thanks for the help Martin.Possibly a life saver.
Turns out that out of the 10 bottles I'd bought one of them was Hydrochloric Acid 4% in the wrong bottle.I contacted the suppliers and they didn't really have an explanation over "it must have the wrong label".Turns out it was in a Sodium Chlorite bottle which is a different colour to the HCl ones.They asked me to test all 10 bottles (I plan on sharing it around) which I did and they'll send me a replacement bottle FOC.THey say it's never happened before but I'm just glad I hesitated and asked on here first.
So they're aware a cock up happened and I'm now all ready to start a procedure after an introductory regimen of course.I'll get the chiropractor out of the way tomorrow and then get stuck in.Thanks again for the support.
