Well I'm taking it if you train Muay Thai at a reputable gym, your cardio/training is dialed in already. There may be some issues with your diet. Check out the other sections on here bout diet but keep that protein up, and good fats and carbs moderately low, il add some more complex carbs to my preworkout/training meal for that little extra oomph. There's plenty of supps on the market but I think losing it at a moderate rate from diet and hard work would really benefit your fighting. Good luck
