To give you the answer: No, there is no injectable form of (Meth)Amphetamine being produced anymore.
You can shoot up Instant Release formulation pills, provided you use a micron filter (0.2µm preferably nylon membrane). I would not attempt to shoot any kind of drug obtained as powder / pill / crystals (read: not inside a sealed sterile vial) without the use of micron filters.
That being said, you can produce your own injectable solution with these micron filters. Since you are making it at home, i wouldn't let the solution get older than 12 hours though. Go purchase some sterile saline (wound wash type), and use this to prep your shot. Sterile saline + micron filter + clean rig for each shot = the most harm reduction you can do, besides NOT SHOOTING UP.
