Salbutamol (Albuterol) is not the exact same thing as Clenbuterone. Salbutamol is safer, more anabolic and you can use it for longer periods without down regulation. If you have 4 mg pills start with one half in the morning and another 2 mg in the afternoon. After two weeks, if you have adjusted you can take an extra dose or two and so on. I would say that don't take more than 12 mg per day.
