I bought mine at GNC. It is a large bottle of powder...unflavored. I believe it cost $15.00

I chose the powder over the cap's as I figured I could easily mix it with drinks that way...or even into foods.

Bottle says (on front):
GNC Natural Brand
COLON PURE
purified psyillium husks
fine ground bulk forming laxative
UNFLAVORED
Net Weight is 24 OZ (which is 113 servings it states)

Hope this helps!

Best to all;
Jake
