I've used injectable dbol, but not oxy.
I used the same protocol as the oral version, which for me is 30mg an hour and a half before heading out to the gym and 20mg about an hour after getting home and having a meal.
I noticed maybe that it kicked in a bit quicker. That's about it. I always get a mild mental boost from dbol along with the weights just feeling a little lighter if that makes sense. Honestly, nothing dramatic between inject and oral. I might be able to inject forty-five minutes or half hour before going to the gym due to the faster uptake but other than that it's the same thing.
