Just want to say that ive tried both intramuscular injections and subq.My first couple of weeks I did the Intramuscular with good results and felt good pre or post.About a Month after that I decided to try Subq injections.All I can say is subq did nothing for me as I didn't feel any results what so ever I tried it for three weeks to give it time to see if I would feel any different,but nothing came out of it so I went back to I/M with good results that I was feeling and seeing when I first started.Just my two cents.
