You should heed your own advise and read up on sub q injections more. This is a subcutaneous fat injection and too much fat will slow absorption to the point it will yield lower than desired T levels.
Maybe watch Dr. Crisler video in this thread or read this link.

While i will admit i was not entirely correct that illustration is complete inaccurate... the suqQ tissue or hypodermis is not just a fat layer but comprised of other tissues to include but not limited to..
Fibrous bands anchoring the skin to the deep fascia; Collagen and elastin fibers attaching it to the dermis;Fat, except in the eyelids, clitoris, penis, much of pinna, and scrotum;Blood vessels on route to the dermis;Lymphatic vessels on route from dermis; The glandular part of some sweat glands; mammary gland lie entirely within the subcutaneous tissue (which are modified apocrine sweat glands);
Cutaneous nerves and free endings; Hair follicle roots; Mast cells; Bursae, in the space overlying joints in order to facilitate smooth passage of overlying skin; Fine, flat sheets of muscle, in certain locations, including the scalp, face, hand, nipple, and scrotum, called the panniculus carnosus...
So yes there is the presence of fat cells but if someone had a considerable layer of fat then going too deep would result in going straight into fat cells, same concept as low bf% person going too deep and going into muscle...
I also will admit my understand of the human body is more extensive than most avg joe so i should make a better effort to explain and not just spout off but by know means do i claim to be a physician... altho i have meet some greatly ignorant docs tho and i attribute that to being educated from medical info back in the 60s 70s 80s etc, being stuck i their ways and not staying current with the times and various advancements made near daily..
