I'm on TRT, I have my own thread about halfway down the page covering my major events over my journey to becoming whole again. Last couple of injections have been a little weird. I inject in my quads like my doc showed me, and the last 2 or 3 times it's felt really weird. Like the whole time the needle is in, it's almost like a mild electrical zap, but constant until I remove the needle, after which the feeling goes away. oddly enough, when I get this, there isn't even a drop of blood that comes back out of the spot where the needle went in. Is this normal or am I too close to the center of the quad? I'm injecting about a hand length above the knee and about half a hand width outward from the center, alternating legs every 5 days, 0.5ml per injection if that matters
