Im in the medical field. SQ essentially becomes IM if you have low body fat and push slightly. If your in the muscle...your IM (intra-muscular).If you have fluff there may be concern. So its not an argument of SQ vs IM. Its about if you can get an insulin into the muscle. There are advantages to the insulin. It is less painful. You can dose more freq due to less irritation/pain/pip...thus keeping levels more even. You can get more accurate dossing. Bottom line in all this game...labs dont lie. Ive done a lot of this stuff and I know what it feels like when the stuff hits and is working. I can get the insulin in into muscle. And its the same but I have the advantages listed above. More freq injections=less aromatization as well. Plus my labs are same with either...so why torture myself with a big ass needle? Not trying to be a know it all...but I do this for a living bros.
