Figure out how to aspirate one handed. Its not fucking hard. No excuse not to aspirate. Maybe in the glutes I could see....but delts and quads....definatley need to aspirate. I have pulled a syringe full of blood multiple times in both areas. Had I not aspirated most of my AAS would have went directly into my blood stream....not good.
As for your shortness of breath and coughing...thats classic hitting a vein symptoms. You either went through a vein or knicked one and a little of the aas got in your blood stream. Not a big deal.
Just start aspirating. I would just do glutes with long esters. So much easier and hassle free.
Wow. You learn something new everyday (hopefully). Didn't read this before my last post, but i'm glad i did. That scares the shit out of me whether it's a big deal or not. I always aspirate butt and quads, but i haven't been in my shoulders lately. Thanks, Burn.
