You should present this question in the Supplement section.

I have only taken UNIVERSAL animal pak supplements and havent really experimented with anything else from them. They are a pretty solid company, but I dont know anything about Natural Sterol Complex. Kinda sounds like a gimmick to me...natural steriod kinda thing...or some herbal sup.
