It's very easy to distinguish pharmaceutical methamphetamine from other amphetamines, for the record. Look for a small white round pill just a little smaller than the oldschool Oxycontin 10mgs and they kinda look like them except instead of saying OC 10, they say OV on one side and 12 on the other.
RX methamphetamine is currently only marketed as Desoxyn, and it is a rather subtle, mild, yet incredibly helpful chemical. It contains 5mg of dextromethamphetamine, so no added PNS side effects that you tend to experience when using racemic amphetamine or mixed amphetamine salts (like Adderall).
Also, one IR dose of Desoxyn (They discontinued the XR version, Desoxyn Gradumet due to massive problems with abuse... It was basically as easy as crushing the beads in an adderall XR and then being left with an abundance of pharmaceutical grade methamphetamine. Obviously, they caught on to people crushing/soaking the beads in water and discontinued the high-dose pills, but it honestly doesn't matter that much. One 5mg Desoxyn instant release lasts so damn long, it lasts longer IME than Adderall XR's, Dexedrine XR, etc, time release. I have never had a stimulant that was time released that lasted as long, or was even damn near close to being as effective as Desoxyn.
