IM Injection Sites - Do They Matter?

[AbsoluteZ3R0]

Excluding subjective pain/discomfort and risk of injury, are there any pharmacological differences between the three major injection sites? I've read in some places that different sites change the absorption rate and even the bioavailability of the testosterone, but I have never seen this on an authoritative medical/scientific document. All other factors being equal, are there any differences between the delts, glutes, and quads as far as pharmacology is concerned? Assuming there are no differences, would it then be useful to alternate between all 3 sites bilaterally so that you only hit each site once every 6 injections? IE: Left glute, right glute, left quad, right quad, left shoulder, right shoulder, repeat

No I don't believe that the site matters, I like your rotations injections sties.

When I mentioned to Dr. Saya that I had switched from shoulders to quads, and asked if that would make a difference on my blood work, he said it wouldn't.

I've been injecting on a daily basis for nearly two years. I joke that I inject anywhere that I can reach. No difference as to location.

Anywhere that you can easily reach and that does not cause undo pain is fair game for either SubQ or IM injections.

As others have said, no difference other than personal preference.
