As far as the results go, the energy boost (which we think was due to a metabolic kick) was very comparable. It was when it came to feeling leaner and the weight loss results where the effects just never seemed to shine like it did with UltraTox. This is also a note that the marketing people at Biotox Gold seemed to focus heavily on so it was a little disappointing that it didn't deliver as well.
Overall Biotox Gold is a decent product for achieving some natural energy, and worth trying if UltraTox is sold out or if you want to do your own comparison. We found a discounted link that we have included below.
