Salbutamol belongs to the category of sympathomimetic compounds also known as stimulants. Salbutamol is a selective beta-2 adrenergic agonist, and is a very close brother of Clenbuterol; both hold the same medical roles (especially for asthma). Other similar nature sympathomimetic stimulants are caffeine, ephedrine, dextroamphetamine, methamphetamine, cocaine, epinephrine, norepinephrine, and many others. These sympathomimetic stimulants act on the nervous and various cells and tissues in the body system through alpha and beta adrenergic receptors. Salbutamol is selective to act exclusively in the beta-2 receptors in the body.

Salbutamol belongs to the class of sympathomimetic drugs, and is known as a racemic drug. It is a beta-2 adrenergic receptor agonist fast acting which is very close to the structure and relationship to Clenbuterol. Salbutamol properties exhibit a variety of effects on different body tissues through their interaction with beta-2 receptors in the tissue cells. This will result, as mentioned above, fat loss, increase in metabolic rate, and light anabolic effect on muscle tissue among other effects. Fat loss and muscle anabolism usually mild highly sought by athletes, athletes and general users of performance-enhancing drugs. It is important to note that although Salbutamol anabolic has proven in humans, muscle gains expected from Salbutamol should not be comparable  with anabolic steroids, especially if the user is in a calorie regimen deficit for the purpose of fat loss. In this hypocaloric diet, Salbutamol help in preserving muscle tissue during a caloric deficit rather than the significant addition of new muscle mass. Regardless, Salbutamol is a very promising (perhaps more than Clenbuterol) for the purpose of fat loss and / or slight muscle gain compound. Experiences vary according to the different individuals. Dosage as with almost all sympathomimetic stimulant compounds (compounds and fat loss in general), doses of Salbutamol for the purpose of performance and physique enhancement are generally inflexible. Salbutamol is used in the same manner as clenbuterol or ephedrine. Salbutamol doses and protocols that is used is actually more similar to ephedrine than it is to clenbuterol, although the effects of Salbutamol at the cellular level are the same as a beta-2 adrenergic agonist receptor.

Although Salbutamol demonstrated greater anabolic capacity in humans, it is used almost exclusively as a fat loss agent. Still, the dose of Salbutamol required for anabolic effects are same as the necessary for fat loss effects dose. The dose of Salbutamol, usually the same for all three user levels (beginner, intermediate and advanced), due to the fact that there is very little flexibility in the doses required for various effects of a stimulant such as salbutamol. As mentioned above, the doses of Salbutamol must ramp up slowly until the maximum dose is reached and the optimal dose peak may be different for each person (some athletes may be more sensitive to stimulants than others) . This is the reason why the dose should be slowly adjusted upward as well as to assess tolerance and determine the best effective dose of Salbutamol.
