Keto helps as well, but that is the reason clen and T3 work so well together. Here is my take on T3, it is a great fat burning drug to a degree, it definately has its risks and its side affects. If your diet is on point and you are using either clen or EC, along with cardio, you can get the same results in 12-16 weeks of dieting without using it and without the risk and the sides, you will also be avoiding the possibility of muscle loss. In the past I have used T3 in the middle of my 16 week diet, but there were flaws in my diet and cardio. T3 can make you really feel flat, and without the proper diet, such as adequate amount of carbs and protein along with anabolics, you will lose muscle. This year I have went without the T3 and am having great results so far, I feel much more muscular and full without using it. The reason I believe for this is that I am adding muscle at this point in my diet from the anabolics since I dont have the T3 burning everything in its path. The anabolics will prevent the burning of muscle, but the T3 will keep you from gaining any while being ran at a high dose. I hope this makes sense, Im not the best at explaining shit. If I decide to do a photoshoot again this year and I feel that I am behind a little, I might use it, but I wont be going up to the amount that I have used in the past which was 100mcg/day.
