I do this often, just not in shot form, Intranasal and oral. I call the nasal mix 631,the oral portion is just oxy m30, real then fake. Anyways, the 631 is 60% Adderall, real ones, so Amp and DexAmp, 30% Cocaine, and 10% Ketamine. The oxys were real to start for a long time, but due to prices switched to pressed lately. I test the presses I get with Fent kit, they come back negative but still hit like a train, so who knows? Anyways went from needing 10-15 real 30s a day to 3 fakes! The cost savings is insane! 300-450$ a day down to around 8$ This is my day to day mix of drugs, all day everyday. Occasionally I'll take a few days away from the ket into the mix as I heard bad things about ket use daily. So far no real negative effects to speak of physically.
