injection basics

So I’m starting my first cycle of TRT and I will be injecting subcutaneously EOD. I understand some people use insulin needles, I’m not super comfortable with the idea of drawing and injecting with the same needle. I’ve been looking for 0.5ml lure lock needles but haven’t found any. I’m...
