Trenbolone Acetate also called Finaplix, which is without a doubt, the most powerful injectable anabolic steroid used to gain muscle. Its anabolic effect is five times that of testosterone and it doesn’t convert to estrogen, which makes it free from side effects like gynocomastia, water-retention, etc. Trenbolone Acetate is not without its fair share of side effects, however. Testicular atrophy, hair loss, enlarged prostate and acne have been reported from using this drug. Trenbolone Acetate will also shutdown the body’s natural testosterone production, which can lead to sexual dysfunction. Trenbolone Acetate has a short-lived ester which means that it must be inject almost daily to maintain steady results. The good news for this is that the drug can be immediately stopped and the body can heal if adverse side effects appear.
