So today was day three of pinning 50 mg of Tren ed. I got about 25% of the way through the injection and the pain was excruciating enough for me to have to remove it pop a new needle on and pin in a different location. I’ve never felt that much pain before, it felt like it was stinging almost like a yellow jacket or a hornet got me. I pinned in a different location and the pain was not there. Could that possibly be me hitting a vein?
