I wish people can pay for trials on products. e.g. In subreddits for hairfall, people cite all sort of very badly done research that shows some chemical in expensive product as effective, for which the only research is sponsored by the company making it. If 1000 people in that subreddit pays $100, it might be enough for a good trial and knowing the active people there, they would likely pay even more. Same for multivitamins, the research on that is so important yet so bad and biased, and getting million dollar crowdfunding should be possible.
