How To Avoid Side Effects

There are ways to avoid adverse side effects of testosterone injections. Here are some of the ways to stay safe when taking testosterone injections:

  • Never buy your medications from unknown sources. This includes purchasing them from overseas, from the black market, from people at your gym, from personal trainers or anyone else that is not a licensed doctor in endocrinology.
  • Only use injections that have been prescribed by a licensed doctor of endocrinology or another very closely related medical field.
  • Make sure to get the right testing completed (blood work,  a physical exam and a medical history) to make sure:
    • You have a low T
    • You are physically well enough to partake in this kind of therapy
    • You do not have any medical conditions that can interfere in a smooth TRT experience
  • Only use a clinic that mandates a first initial free consultation.
  • If you are under 30, understand that you may still be growing and that testosterone replacement therapy is not for you. It is only safe for those with low T who are over 30 years old.
  • If you are looking for a weight loss program or to increase your sex drive or muscle mass, TRT is not the way to do it.
  • Only use a clinic that mandates testing to take place to make sure you are dealing with a bona fide testosterone deficiency. If you use low T medications when your body is already producing enough of this hormone on its own, this can lead to testosterone injections side effects aggression or other negative issues.
  • Only use a clinic that uses the very best top quality medications that you know are real and authentic.
  • Always check your medication vials before self administering them into your body. Look for any particles that may be in the solution. If you find any, do not use it. This can be bacterial residue from the manufacturing process and if you catch this before using the injections, you can avoid some possible serious testosterone injections negative side effects.
  • Do not use medication if it looks murky or cloudy. If you have any questions about your vials of medication, do not take the chance of using them; throw them away.
  • Never inject a testosterone shot directly into a vein. They are only to be injected into one of the following muscles:
    • The buttocks
    • The deltoids
    • The thighs

Rotate injection spots on the body. Never use the same place twice, as this can cause irritation, redness or swelling.

One of the best ways to avoid low testosterone injections side effects is to always ask questions as they arise. If you are not sure about something, have a question about how to prepare your medications, how to administer them, what you are feeling or anything else, have a discussion about it with your clinical advisor. Openly talking about testosterone injections and side effects is the best way to have a smooth TRT journey and to reap the best benefits while avoiding problems.
