Challenge to all t-maggers - A2 adrenergic antagonist alternatives

O.K. t-maggers, Dr Doug Kalman if your in heres a question I doubt anyone can answer. Dan Duchaiane says in Bodyopus Yohimbe is one of the rare A2 adrenergic antagonist available implying there are others!
Does anyone know of others?
Yohimbe is banned where I am and it does wonders for my love handles when I compete.
