Depends if you ever took them or not... If you want to go not expensive and get the extra edge on energy you can go natural! The only problem with natural fat burners are they are filled with roots and trees so you will end up burping and it will taste like oregano! LOL
There are some really inexpensive Fat natural fat burners like ripped FX i think its like a black bottle with flames on it. I started on that and lost a bunch of fat! The i progressed to ECA and that really got me good!
Ideally is not to abuse the fat burner! You take it for 2 or 3 weeks then 1 or 2 off then 1 or 2 on!
If your playing sports i think ECA will be a little much as you are already putting alot of stress on your heart... dont need the extra pressure!
If your NOT fat and you dont need to shred extra pounds i would recomend you get some SuperPump250. a Good energizer shake you drink 25 min before your game... or your physical activity and thats gonna give you a bunch of energy!!! you gonna think your Michael jordan
But if you really wanna get ripped.. You spend alot of time in the gym.. ECA... Tight Hardcore is nice! i used TIGHT one time.. Strong shit for burning fat!!!
But i would much rather recommend a nice energy drink like superpump250 with Vitamins!! Really important for sports and mix some glutanime with your shakes or drinks ... can be very very good for your joints from wear and tear on the court
Glutamin is cheap also hidden secret!
