I have an interesting question to ask the experienced folk over here. I am curious about what substances can be injected subcutaneously, with relative safety. Of course, I know test is one item. I am not asking because I plan on taking anything (other than test) right now. Since I am taking test subQ, I became curious about what other substances could be administered via the same route. There is not much info on this online, So I am hoping you guys can shed some light on this matter. Thank you.
