I perceive benefits from it, if that's what you mean by "work". I've been using it for over two years now and consider it an integral part of my protocol. I'm not encouraging all and sundry to hop on it. I think selegiline is more appropriate for older guys—who are more likely to have rising MAO-B activity. But you will find recommendations for age-dependent doses to as low as 30 years old. It's also possible that for some applications selegiline would compare favorably to dopamine receptor agonists.You mean it did work ? How long have you been using it for ?
