Lets assume all who read this are going to supplement with Trenbolone responsibly and if you do the odds of a positive experience are far more in your favor. However, because it is impossible to predict if you have never supplemented with this hormone before you are highly advised to stick only with the Acetate version, often referred to as Tren-a. Trenbolone-Acetate is by many the preferred Trenbolone hormone but for the first time user it is the only logical choice The reason is simple; if you fall prey to the sever side effects of Tren you can simply discontinue use and have the hormone cleared from your system in a little more than 48 hours. If you choose a larger ester based form such as Trenbolone- Enanthate and fall prey to sever Tren side effects its a different story; it will take weeks for the hormone to clear after discontinuation.
Many abusers who inject anabolic steroids may use nonsterile injection techniques or share contaminated needles with other abusers. In addition, some steroid preparations are manufactured illegally under nonsterile conditions. These factors put abusers at risk for acquiring lifethreatening viral infections, such as HIV and hepatitis B and C. Abusers also can develop endocarditis, a bacterial infection that causes a potentially fatal inflammation of the inner lining of the heart. Bacterial infections also can cause pain and abscess formation at injection sites.
