is it a pill or legit vials ? if you are talking about pills it is a big no no, it is even worse than IVing them as the fillers and binders can get stuck in your tissue and the chances of getting an infection/abscess are much higher.
edit: if it is a legit vial, then yes, it can be used intramusculary tho it would be pretty much as the IV in the sense that you don't get more out of it than orally. I got a strange attraction to the needles and sometimes I got periods when I want and I indeed do IV almost everything but in some cases, there are no benefits to do it as dissapointing as it may feel.
