Adderall & Ritalin

Do either of these drugs affect Beta 2 receptors?

If not, what do they affect?

I could use google and find a long scientific explanation somewhere, but I’m hoping someone here can give me the short and sweet version of it.

I take adderrall and I think they do affect the beta 2, or at least something related to fat loss. I have a prescription for 30 mg 1’s.
I do notice I stay leaner on it, but I think gaining muscle is also difficult while on it.

Hmm, have you noticed how long it takes for an increased dosage becomes necessary to obtain the desired effect?

I hope my body doesn’t adjust to it as quickly as caffeinne/ephedra.
