Yikes...no need to harpoon yourself Mica. I've been using Dr. Crisler's method for injecting Test, and it works like a champ. Use a 1/2", 29ga insulin pin to the outer quad, and you won't even feel it. Since Test is oil based and viscous, it takes me about 45 sec to draw it into the syringe...no big deal. Sit down, take all the weight off of your leg, and totally relax your quad muscle. Take your time and inject slowly, hold pressure on the injection site after needle removal, then massage for a minute. End result is no bleeding, no Test leaking out of the injection site, and no pain. Easy peasy, Japaneezy.
For any injections into my abdominal area, I always use a 5/16", 31ga insulin pin. Can't really feel that either. Just remember to inject very slowly. I try to save my abdominal area for HCG and Sermorelin injections only, but I am still experimenting with in that area with Lipo-C and Tri-Amino.
I tried a Lipo-C injection (1mL) into my deltoid a few days ago with a 3mL syringe and 5/8" 25ga needle. I won't be doing that again. No bruising, no irritation, and it didn't burn going in (like I've read about), but my arm was sore like I got punched by Nelson. After about 3 days, the soreness went away. I tried it again with a 5/16", 31ga insulin pin into the abdomen (only .5mL) this time, but I definitely felt the burn. No bumps or red spots though. I guess I'll go back to the other deltoid with a 1/2", 29ga insulin pin, and see how that goes. I just love being a lab rat.
