All these compounds, such as clenbuterol, albuterol, ephedrine, t3/4 - none of them were ever meant for fat loss. Therefore, they will cause a lot of side effects at the dosages that you need to take for fat loss. Besides, one of their major downsides is that they will also eat up your lean mass too - not only fat. Better use something that was created for fat loss or recomp, such as Cardarine GW. It is a very effective fat burner, it will even increase lean mass, and will not cause any side effects at all. Additionally, you get with cardarine such benefits as endurance, recovery, and cardio performance. Therefore, it is a much better alternative. Also, if you combine it with N2Slin you will get some pretty amazing results.
