Yeah lots of guys can get away with one oral only cycle. eight weeks one hundred mg per day. go for it. If you start to feel like shit around week four you're one of the normal ones that din't get lucky and your test is supressed and you need to stop.
No you SHOULD NOT run an oral only cycle I don't recommend it but it won't kill you or permanently damage you as long as you stop if you start to feel like shit. And again, maybe once.
