Testosterone can be administered in a variety of ways, but the main way it is administered is by injection. Other AAS are mainly used by injection, but there are some that can be used orally.
Common injection sites are the buttocks, thighs, or upper arms. Users should use a new needle for each injection and disinfect the injection site prior to injection. Some users may experience pain at the injection site, which is usually temporary and goes away within a day or two. If needed, apply a cold compress to the injection site. It is best to choose a different site for injection each time, so as not to form scar tissue or cause excessive local hormones.
Steroid testosterone injection is in the muscle and should be avoided when injected into blood vessels. Suction before injection is important to confirm whether the needle is inserted into the blood vessel. Suction is the plunger that pulls the syringe back after the needle is inserted into the muscle. If blood is found in the syringe at this time, it means that you have hit a blood vessel and need to change the injection site.
If testosterone or AAS is injected into the bloodstream, it can cause a number of problems. The most serious problem is the increased risk of heart attack or stroke. This is because injected testosterone or AAS liquid can thicken the blood and cause arteries to block.
Only when testosterone or AAS is injected into the muscle can it be guaranteed to bind to the receptors in the muscle and promote muscle growth. If testosterone or AAS is injected into subcutaneous fat, it is absorbed more slowly by the body, affecting the effectiveness of use.
Injecting testosterone into the wrong place can also have serious health consequences, because testosterone affects brain chemistry.
In general, inject AAS such as testosterone with less care and make sure the hormone is injected into the muscle tissue.
AAS, such as testosterone for injection, are basically stored in oil-based carriers and released slowly into muscles to play their role. Appropriate needle sizes are needed, as these oily, high-viscosity preparations can be difficult to extract from small bottles. The No. 23 1-inch and No. 25 1-inch needles are standard for oil-based AAS such as testosterone. The smaller size of the needle helps reduce the likelihood of tissue scarring from long-term injections. A needle larger than 25 size can be used, but it may take longer to extract and inject an oil-based solution.


Testosterone plays a key role in male development through its anabolic and androgenic effects. Anabolic effects include increases in muscle mass, strength, bone density, and bone maturation. Androgen effects include the maturation of sexual organs, maintenance of secondary sexual characteristics, including a deep voice, and the growth of beards and body hair. The most ...
