I recently switched from a reg pin to a 29 guage 1/2in insulin needle for my Trt shot. I've been reading that you need to have lower bodyfat to hit a shallow IM shot and was wondering around what level of fat is ok? I'm not sure of my percentage but I'm about 5'7 and 160 lbs, and carry excess fat in the waistline more so that anywhere else. I've used thighs, chest and delt shots, and since upping the trt dose I went from 583 to low 900's so I'm assuming the slin pin is working. Although my libido seems to have dropped when I switched. Is this just all in my head? Or is it a possibility.
Thanks
