Amerisciences - Good or Bad?

I recently came into contact with a doctor who tried to involve me with the multi-level marketing company Amerisciences. I have been a loyal user of Biotest products for almost 2 years now and with great result.

So this overweight Dr. lady comes into my office spouting of Bioavalability, how much is your health worth to you, this doctor and that doctor developed this or that, Cris Carter gave his testimonial, BLA BLA BLA… The majority of their products have extremely inovative names like Slim, Energy, Focus, Sleep, etc. and usually run about $69-85 per month for each supplement. My Question is: Has anyone tried these products and benefitted from them?

As soon as I saw their Protein Powder had Soy it was a no go!

Thanks for any feedback
