The following is completely hypothetical and for entertainment purposes only. I haven't cycled in a couple of years, but I exclusively use dorsogluteal and ventrogluteal sites. Better absorption and great capacity of volume to minimize risk of abcess formation. Ventrogluteal can be unnerving at first but it is great alternative to quad injection. Dorsogluteal requires a little flexibility but it can be done. Remember upper and outer portion of glutes to avoid the sciatic nerve. I typically use a 23G 1.25in needle.
