Testosterone is a hormone that can be injected under the skin in order to increase levels. It can be used to improve muscle growth, reduce fat and to aid in erectile dysfunction. Injections can be given by a doctor or by using a testosterone injection kit at home.
When injecting testosterone it is important that the injection site is clean and free of dirt, bacteria and anything else that could cause an infection. It is also a good idea to wipe down the area with an alcohol pad before injecting. Injections into the wrong area can lead to a host of problems, including serious infections.
The most common way of administering a testosterone injection is intramuscularly. This involves injecting the hormone into muscle tissue in a specific location, usually the deltoid in the upper arm or the glute in the buttocks.
Recently, however, subcutaneous injections have become the preferred method of administering testosterone. This is because they are less painful and do not require the use of a large needle. This can be a big benefit for those who undergo testosterone replacement therapy on their own.
Before you inject, make sure the syringe is clean and that there are no air bubbles in it. Then, with the weight off of the leg, gently stick the needle into the area where you are going to inject it. Then, pull back on the plunger ever so slightly (this is called aspirating). This will ensure that you are not injecting into a vein. Then, push the needle all the way into the muscle, making sure that you are not in a vein (you will know if you are if you get any blood return on the syringe).
