It's okay to take T by intramuscular or sub-Q injection. Either are okay. Those risks I mentioned are pretty low for intramuscular injection anyway, at least for the sites that are usable for self-injection.
The only really risky injection site for T also happens to be the most impractical to reach for *self-injection*. It's the dorsogluteal site, on the buttock muscle. There are safer and easier sites for self-injection, so just don't use that one.
