Yes, it was interesting. 3 doctors 'experimented' on themselves with various pills. Appetite surpressants, fat blocker. Can't remember the other one and I think they were over the counter or available on the internet. Only half watched it, but have recorded.
The one doing the fat blocker lost a fair bit of weight and said he would use it again, but only with caution as his blood pressure rose quite dramatically.
I think there was a warning about some being either being rather unsafe or ineffective. Was multitasking at the time...missed chunks.
