I'm guessing you mean "sustanon"?
If that is what you are referring to I would highly recommend doing intramuscular shots. Not subcutaneous. You'll get much better absorption by getting the oil deep into the muscle. Plus you run a higher risk of getting an abscess with sub-q. I also think injecting in the fat layer has a much slower activation time. You could probably get away with doing 0.5ml sub-q injections, but if you're running sustanon then you'll probably be injecting more than that.
To answer your question... Yes you can. I would advise against it though.
