Anvirzel or OPC?

From the information I gathered, OPC is below $100 at:
http://www.sutherlandiaopc.com/

and Anvirzel can be purchased for around $3000 at:
http://www.saludintegral.hn/


But then according to this site:
http://www.cancertutor.com/Cancer02/Oleander.html

it says you have direct pipeline at Nerium Biotechnology out of Canada, what does that mean? Can I purchase Anvirzel from
http://www.nerium.com/
? Or do I need to contact you?

Better yet, which of these products do you recommend, which one is more potent? Thank you in advance. Tweet
