Interesting.
Reading what you wrote "consistently higher test levels" could mean a few things.
First, if I inject 200mg in my body my body will have 200mg in it regardless of where I inject.
"consistently higher test levels" maybe related to how quickly the body absorbs it and gets it in the blood stream. If a glute shot provides "consistently higher test levels" this could mean that the absorption into the blood is more even if you get a glute shot. Conversely, if I inject in the delt it maybe gets absorbed into the blood stream quicker (possibly because the muscle is smaller?) leading to a greater spike after the injection leasing to lower, or more uneven, test levels thereafter.
Hypo: 200mg test shot: one in the delt one in the glute
Glute Blood Levels: possibly the levels would be more even over, say, the court of 5 days, say 40mg per day.
Delt Blood Levels: possibly (this is pure speculation) the initial spike in the blood level is say 80mg and it goes down over the next four days say at 30mg a day (just to make it even)
In sum, the consistent of test in the blood is higher with the glute shot over the same period of time. The greater issue is that 200mg is 200mg and the body has it all. Maybe a glute shot is better for more level test levels in the blood – I am not sure without reading the article.
Not sure if any of this is right. Who knows.
