Nah, they just take regular dextroampehetamine - methamphetamine is particularly neurotoxic.
There probably is some shadowy special-forces division that gets the cool stuff but I gather that even amongst the USAF's endurance fighter squadrons you won't see much stimulant use: it's too much of a liability, and the services really don't want human-liabilities piloting hundred-million-dollar supersonic death-machines.
Fun-fact: the Nazis used meth, then known as "Pervatin" - but then they also mixed it with cocaine and oxycodone and called it "D-IX" - sounds like quite the party: https://en.wikipedia.org/wiki/D-IX
