Thanks for the thoughts. We&#x27;ve spoken with a lawyer who specializes in FDA issues. We will have informed consent waivers for participants.<p>Rob does have formal training in scientific ethical issues and is more than competent on the subject.<p>Also, L-Theanine is something that you can purchase at the grocery store as a food supplement and it has an excellent safety record and no known toxic dosage.<p>If it makes you feel better, we are a supplement distributor that happens to help you record whether or not the supplements actually work.
