Trenbolone Enanthate 200 - Xeno Labs (Int)

Trenbolone is a powerful anabolic steroid invented in the 1960s.

Here’s what it looks like in liquid form:

The name trenbolone comes from the scientific name for the molecule: tri-en, 17b-ol, 3-one.

Here’s what it looks like next to a testosterone molecule:

Trenbolone

Trenbolone was originally created to increase the appetite and muscle mass of cattle, while reducing their body fat, and it’s still used for this purpose today under the brand name Finaplix-H.

In 1980, a French pharmaceutical company released a form of trenbolone for humans called Parabolan. The drug was intended for people suffering from muscle wasting, AIDs, or osteoporosis, but was eventually pulled from the market in 1997 due to the side effects (which you’ll learn about in a moment).

Since then, all of the trenbolone produced for humans has been made illegally in underground labs around the world.

Chemically, trenbolone is a modified form of another well-known anabolic steroid: nandrolone. Also known as Durabolin or Deca-Durabolin, nandrolone has similar effects in the body as testosterone with slightly milder side effects, making it one of the most popular steroids in the world.

In fact, one of the most popular steroid combinations or “stacks” in the world is testosterone and nandrolone.

We don’t need to get into the exact structure of trenbolone, but the short story is that by fiddling with the structure of nandrolone, scientists created a steroid that’s three times more powerful than testosterone—trenbolone.

Trenbolone also produces different side effects than testosterone, which is the primary reason bodybuilders have taken to it so enthusiastically. You’ll learn more about why in a minute.

You’ll often see the names trenbolone acetate, trenbolone enanthate, and trenbolone hexahydrobenzylcarbonate (aka trenbolone hexa) thrown around instead of just trenbolone.

This is because trenbolone is always combined with other chemicals to reduce the speed at which it’s absorbed into the blood.

If pure trenbolone is injected into an animal or person, it’s absorbed from the blood too quickly to exert its full muscle-building effects. To slow the absorption of trenbolone, scientists combine it with other chemicals such as acetic acid, which slows its release and prolongs its effects.
