No problem. Good luck! Were you ever tested for antibodies to A & B? As there are other reasons (injection technique, scar tissue, dose, etc.) that could lead to no results.I'm not sure how it works in terms of if you already developed an immunity to another formulation, but perhaps because the proteins are what sets off the reaction and doesn't allow it to work, with a protein-free complex (Xeomin), you could still respond? of course, i'm not exactly an expert on the topic! I do get the impression that if people do not have an immunity to Botox, with Xeomin (or NT-201), there is almost no risk of developing it from that point forward.
I'd really be curious as to how it works out for you.
