You hit a vein. It happened to me this weekend doing a glute shot forgot to pull back on the syringe this one time lol. HappensFuck I feel for you man I just had the same thing happen with 1 ml of test and 1 ml of deca, in the quad also, got about 1 ml in and all the sudden extreme hot flash and could feel it in my lungs stopped injecting immediately but it was to late, felt like I had the flu for about 24 hours
