Affiliate Marketing Secrets

I’ve been searching both clinicaltrials.gov and http://crnet.mgh.harvard.edu for local trials at harvard affiliated hospitals, and it seems like everything requires you to be suffering from aids or cancer or some other horrible terminal illness. I know I’ve seen things like intestinal studies where you just get an endoscopy or just getting MRI/PET scans and it said you got paid $500-600 for them, but I can’t find anything like those anymore and healthy people ones are usually like blood donations for $25 a visit or something worthless like that. I know about sleep studies, but I can’t do them because I have a lot of responsibilities here at home.
