Here's a quickie tech for IM injection: IM injection it easy, best place is you thigh between your knee and mid to upper thigh. Just kinda poke your finger into your thigh on the outside to half way down the side of your leg and try to find the muscle in your thigh under the fatty epidermis. Push the needle thru your epidermis and you can feel when it hit the muscle. Then pull stopper back after you get the needle in to be sure you aren't in a vein or artery. If blood comes into syringe, do not inject...pull out needle and try another IM site. Slowly push the stopper on your syringe in because if you do it too fast it will start to sting. It usually takes me a 20-30 count to get a full 1ml into my muscle. IM injection doesn't have to be all the way inside the muscle but it can be on the surface of the muscle as well. Most ppl have syringes with 1/2" needle pins, these work but if you want into the muscle you need a 1" needle. I use the same types of insulin syringes IM or IV. "1ml, 1/2" needle pin, 27-30 gauge"...I usually use 28 gauge. For IM the bigger the needle point the faster to get the injection in, but a few seconds isn't a hinder to me, while IM'ing. nomad bloodbath
