I've been thinking about doing this for quite sometime. Basically, i was thinking of doing something like the Hoodia pills. I can buy the substance in bulk, and create the pills at home and bottle them up. You do the free trial thing where they pay $6.95 and then bill them later on in like 14 days for like $80. The pills and bottles would cost you like $100 to make like 30-40 bottles. So quite a big ROI. Can anyone comment on the legal/doability of the method? How hard would it be to do it in the US? Do you have to get approval from the FDA?
