There are no hard and fast rules for how long you can stay on <a href="http://www.t-nation.com/store/products/hot-rox-extreme"target=“new”>HOT-ROX Extreme. The label states to use it for a minimum of one month, so using it for longer is perfectly fine. It will keep working, though you may get used to the stimulatory components and not “feel” them as much. But HOT-ROX is still doing its job as a fat burner.
Many do prefer to cycle fat burners though. You may want to cycle off during the middle portion of the 10 week cut, then start using HOT-ROX again during the last 4-6 weeks before the competition to really fine-tune your physique. The extra energy and mood-enhancing effects of HOT-ROX would be really appreciated during the month before you hit the stage.
During that time when they’re cycled off HOT-ROX, many prefer to use <a href="http://www.t-nation.com/store/products/carbolin-19"target=“new”>Carbolin 19 (which is actually a component of HOT-ROX) and <a href="http://www.t-nation.com/store/products/seven"target=“new”>Se7en, or a stack of the two together. Both will help with fat loss and preserve or build muscle during your strict prep period.
While Se7en is marketed toward women, it works very well for males who are in a strict fat-loss phase. This stack has proven very effective for people with your goals.
After you run a cycle of Carbolin-19 and Se7en, you can finish out by getting back on HOT-ROX at the end of your cut when you probably need it the most.
