In which muscle to inject?

Hi,

Does it matter in which muscle you inject testosterone? I've read that injecting into gluteus maximus is the best way. But, what if you'd choose another muscle? Would it change anything? Thanks.
 
Injecting into the glutes is dangerous, you need to inject IM or SQ into the outer quads and or shoulders using a 27-29 gauge 1/2 insulin syringe, no need to use those 1.5 inch harpoons!

injecting into the glutes is not dangerous as long as you inject into the upper outer quadrant. In fact, IM glute injections are standard technique.

I am sure your Doctor should talk you through step by step, I take you are going on TRT via your doctors advice?

I am not giving myself shots. Not yet at least. Nurses are doing it so far.
I am just asking, because i want to know if there's a difference in injecting to various muscles. Because if i were doing shots myself, the gluteus area is not that easy to reach.

Regarding the dorsogluteal (upper outer quadrant) injection which was considered the standard old school method and although there are major nerves and blood vessels including the (sciatic nerve and superior gluteal artery) as long as the injection is done in the upper outer quadrant it should be safe mind you one could still inject in the wrong area and nick the sciatic nerve. There also tends to be more fatty tissue in this area and in some studies it has been shown that when even using the standard 22 gauge 1 and a half inch needle in heavier set individuals the injection was subcutaneous and not i.m. as the needle length did not reach the muscle tissue.

The more common method is injecting in the ventrogluteal which is sparse of any major supply of nerves or blood vessels while remaining well perfused from smaller branches. There also tends to be less subcutaneous fat and a thicker muscle mass than the dorsogluteal.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
