Thermonex was BSN's first thermogenic 'fat burner' supplement and has quietly proven itself to be a really good formula in terms of ingredients and results. 'Quietly' because Thermonex has been somewhat overshadowed by the blockbuster success of other BSN products like NO Xplode, Syntha 6, and BSN's 'other' fat burner Atro-Phex. But Thermonex is a still a great choice, maybe the best chice, for anyone who needs and wants a straightforward weight-loss support - not a complicated kitchen-sink formula that tries to do 10 different things at once. Notice the robust potencies of all the ingredients in Thermonex? That's a sign of a good formula. You won't find token ingredients in token amounts, so you'll feel Thermonex working from the very first dose instead of waiting around for results and wondering whether or not your product is working. Use in conjunction with your carefully-planned diet and exercise program for best results.
