I have been doing t400 and tren e for a couple weeks now and have been doing a 21G 1.5 inch in the glute and have had lots of pain. I cant find any 1.5 inch 23G anywhere, only 1 inch. So i tried it out for my last injection and it felt so much better. I'm just not sure if the inch goes in deep enough or how I could tell if it wasnt? I want to keep using these if possible.
