In the regular (non "XR") Adderall tablets they can contain 5mg, 7.5mg, 10mg,12.5mg,15mg, 20mg, 30mg which are of various colors. The capsule version (Adderall XR) can come in 5mg, 10mg, 15mg, 20mg, 25mg, 30mg. I have never seen any other version available in any pharmacy or have seen any higher strengths anywhere online. I think hes lieing to you or he doesn't know what hes talking about.
