Yes I am only going to do subq on TRT. But i am confused a bit. I use 5/16" 31 g slin pin. This is a tiny needle, but I do not have fat on my quads or shoulders ( i like to believe

), I only pinch skin on thighs. So if i pin 5/16" straight in my quad wihtout pinching the skin - is it going in to muscle, fat, or layer between fat and muslce. Same with shoulder, not sure where it goes. on typical cycles i only did IM with a longer needle so I know it was into muscle but with 5/16" needle size i am not sure any more. And if it is going into muscle would such a tiny needle cause damage in the long run with puncturing muscles essentially forever
I know in my lower abs area it goes into fat
