Really? I thought adderall (contains 1/4 dextro-) or vyvense (don't know which amphetamines it contains) were pretty common.

Adderall is a mix of d- and l-amphetamine.

Vyvanse is d-amphetmine bound to lysine, turning it into a prodrug (which means your gut chemically cleaves off the lysine and, conveniently, you're left with d-amp sitting in your gut).

Vyvanse was a wonder drug for me. Not only helped me concentrate it made me more outgoing and confident. Left me with horrible dry mouth though.
