What is trembolone?

Trembolone is an anabolic steroid known for its high potency. It was never approved for human use but was originally developed for veterinary purposes to bulk up cattle. It's 500 times more anabolic and androgenic than testosterone, making it popular in bodybuilding, despite its legal status and potential health risks 1 2. The drug is often referred to as "trend" or "tren" in bodybuilding circles.

Trembolone is often misunderstood or misused, with some people even using it in unconventional ways, such as inhaling for supposed performance benefits, though this is highly questionable and likely unsafe 1.

In sports and fitness discussions, trembolone is noted for its significant anabolic effects but also for the controversies surrounding its use due to legality and health risks 3 4.
