I would caution anyone to think very carefully about the risks.
I will name my friend. Dr Kevin Valiant. He as a medical student like many participated in tests. During the course of his studies and later whilst working as a doctor Kevin became very depressed and always blamed his illness on the drugs he had trialled. And he spent quite a few years trying to research exactly what he had been given.
Sadly Kevin was never able to cope and commited suicide.
At the inquest his father basically stated the above.
