I can't believe 5 years later we are still asking the same question. As for injection I did 150mg eod and it worked great, no abcesses, etc. and no worse than any other injectable. I also used the tabs and they didn't seem to work as well. My take is if it is the injectable form, inject it. If it is the oral form swallow it. Seems to me that was what each was designed for.
I am sure however you use it it will work.
