Dr. gave me glycos to take...from mannetech...Im skeptical

When I read the mannetech brochures I feel it seems like a cure all multi level marketing thing where this "product" will cure everything "just listen to Julie's testimony her brain tumors have just melted away and now she can bend steal with her bare hands"...Ive seen so many of those that it naseates me.

I would love to know if they are good and work, from someone intelligent and not connected to mannetech or making money...
