Deprenyl Versus Bromo, hmmmmmmmmm. I just read smart drugs 2. A great read on cognitive enhancement etc. They do speak about deprenyl in depth.
As far as whats best I could not say but I am almost positive they works thur almost indentical mechanisms of action. I believe Deprenyl is a stronger drug as with dose escalation it can raise brain dopamine levels, not just blood levels. Also deprenyl has a very long half life and supposedly have neuroprotective effects. I have yet tried it, but will be trying it for cognition enhancement after I exhaust the natural nutrients . I.e DMAE, choline,SAM-e, maybe some tyro,phyl, and L trypt
