Their response- TABLETS
That's right, just simply, TABLETS. No active ingredients, no fancy promises, no side-effects.
After all, if a placebo works despite having nothing in it and all homeopathic preparations are guaranteed to contain no active ingredient, then why should any further info be necessary.
TABLETS come in a handy glass bottle with an eye-catching red cap (my idea). Keep some handy in case you feel like you need a tablet, because what you see is what you get.
