Good clinical trials take time and money. There are many hurdles to go through including forming a team, going through ethics review, safety review, FDA approval building the protocol, establishing dosage, reporting adverse events and on, and on and on. A drug has to go through many phases to be approved as a treatment and there are very good reasons for that, mainly for the safety of patients and to accurately determine efficacy of the drug.
N=1 very seldom brings information that can be useful to a patient population other than having patients rushing to buy supplement or a drug out of India/Africa, and risking their health or their money in the process. If you like the researcher's work, support him through a gift of money, or by fundraising.
