well you can always do this. Go to GNC and buy a new unopened bottle of Ripped Fuel and return your Opened bottle (you got off the net) for a full cash back refund, then just sell the GNC bottle you bought to someone else for a little below what you paid. That's worked for a lot of people I know.
As for Hydroxycut, the new formulation is Ephederine free, so you might consider Dymetadrene Xtreme by AST Labs, you get 100 doses of 20mg Ephedra, with Adrenaline precursers thrown in all for around $18 off the net.
Thats what I use, since Hydroxycut is now not in my interest
