I am currently doing a protocol of 40 milligrams every other day of testosterone where I inject into the glute with a 5/8 inch 25 gauge needle. I'm running low on those and have back filled several 30 gauge half inch insulin needles and would like to continue to inject intramuscularly. My concern is a half inch into the glute might not get to the muscle so I'd like to inject into the chest muscle. The reason why is I have trouble injecting into the deltoid for whatever reason. Do you guys happen to see any problems with that spot or should I do the quads instead? Any help or advice you could give would be much appreciated! I've been on trt now for about 7 weeks and I'm loving the results. I also take HCG 200 I use every other day usually with the testosterone injection. Again I appreciate any feedback you guys can share with me.
