Seems to work okay - but not fantastic (Okay in its price range)...
Others in this product class seem to give results that stand out (like you know it works -- not all in your head).  I have  been using just 2 scoops per serving instead of three that might push reaction into the 5**** range.  Its probably all boils down to combo of ingredients as to which Mumbo-Jumbo works best for you.  Each person might get a different reaction  based on what they have or have not been using for this purpose.  It's really trial and error (experiment)  to get to one or two products you really like (& seem to be worth the exorbitant  prices - in some cases).
