Accelerated Rapid Release Formula! High Velocity Weight Loss Extreme Energy...Fast Maximum Potency Liquid-Filled Softgel Dietary Supplement Works With Any Sensible Diet and Exercise Program Zantrex Black...More Weight Loss than Hydroxycut and Lipozene To be fair, it's difficult to compare individual clinical trials because of inherent design variance. Nevertheless, we used Hydroxycut's and Lipozene's own studies (the ones they rely on) and our published, double-blind clinical trial (the one we rely on) to do the math. Note for customers of Zantrex-3 High Energy Fat Burner or original Zantrex-3: High Energy Fat Burner (red bottle), the original Zantrex-3 (blue bottle), and Zantrex Black are different formulations that work in different ways. For maximum weight-loss effectiveness are extreme high energy, take Zantrex Black every day as directed.
