Anyone ever do an intradermal testosterone injection? I wonder of it would increase DHT??

I'm thinking about trying it with a small amount, maybe 10mg? What do you guys think? Where should I inject it? What size needle should I use for this? The smallest I have is 23g, I know I probably need something smaller for this.
Intradermal injections are not all that easy to do, but maybe you have experience with them. I would use a short needle insulin syringe, no bigger than 28G if you were going to try.
