2, Estra-4,9-diene-3,17-dione Applications:
Dienedione, also known as estra-4,9-diene-3,17-dione, is a
synthetic, orally active androgenic-anabolic steroid (AAS) of the
19-nortestosterone group that was never introduced for medical use.
It is thought to be a prohormone of dienolone. The drug became a
controlled substance in the US on January 4, 2010, and is
classified as a Schedule III anabolic steroid under the United
States Controlled Substances Act. Previous to this, it was sold as
a bodybuilding supplement within the United States, and often
mistakenly marketed as a prohormone for trenbolone, a veterinary
steroid. Prior to its scheduling, it was part of a number of
supplements that were seized during FDA enforcement of
Bodybuilding.com for selling unapproved new drugs. The actual
active metabolite, dienolone, is almost identical to trenbolone
structurally, but lacks the C11 double bond.
Dienedione, commonly known as “tren” or “x-tren”, was one of the
most popular “prohormone” products of the noughties, being sold
from 2003 until finally becoming illegal in the United States in
Although it was known as “tren”, it did not convert into the
veterinary steroid trenbolone as was initially suggested by some,
instead converting in vivo into the steroid dienolone; structurally
similar to trenbolone, but with one less double bond.
Dienedione is a non-methylated steroid that converts to a steroid
known as 17b-hydroxy-estra-4,9,(10)-dien-3-one (dienolone).
Although dienedione may have some anabolic activity on its own, it
gets most of its effects from conversion to dienedrone by
interaction with 17b-HSD. This steroids overall effects are
somewhere between trenbolone and nandrolone.
Dienedione is known for causing night sweats via its powerful
thermogenic effects similar to trenbolone. This thermogenic effect
makes dienedione an excellent choice for dropping bodyfat during
As a 19-nor this compound has decent progestational effects which
may lead to gyno symptoms, libido loss and aggressive mood swings.
Part of the reason gyno may be a problem with this compound is also
because it lacks androgenic potency and down-regulates DHT levels
during cycle, which is the body’s natural estrogen blocker.
Dienedione does not convert to estrogen, although it can still lead
to the side-effects mentioned above. Because this compound is not
17aa liver toxicity is not really a concern. However some users
have reported elevated liver enzyme values during cycle, although
this could be related to other factors.
Users usually experience rapid gains in strength and aggression,
followed by significant weight gain after several weeks. The
results are generally fairly lean with only minor bloat due to the
Dienedione can be used as a standalone. In an effort to prevent
libido loss and gyno, it may be stacked with testosterone or one of
its non-aromatizing metabolites to help keep DHT levels elevated
