estra-4,9-diene-3,17-dione (Tren)

Estra-4,9-diene-3,17-dione is a powerful pro-steroid chemically similar to the anabolic agent Trenbolone.
Tren is a popular over-the-counter anabolic steroid/pro-hormone. Tren as a nomenclature can be confusing, as there are four different compounds commonly referred to as Tren:

17b-methoxy-trenbolone
13-ethyl-3-methoxy-gona-2,5(10)-diene-17-one
estra-4,9-diene-3,17-dione
19-Norandrosta4,9diene-3,17dione

Tren is a very strong non-methylated compound and can negatively impact blood pressure, lipid values, cholesterol levels and will put strain on the endocrine system. One downside of Tren is the potential of progestin induced gyno or flare ups of existing gyno. It's recommended to run P-5-P on cycle at the bottle recommended dosage. User who experience flare-ups should increase the dosage into the 150-250mg range.

When in the body, estra-4,9-diene-3,17-dione completes the conversion to Trenbolone. Trenbolone is a potent anabolic steroid, which binds to specific receptors present in reproductive tissue, muscle and fat. Trenbolone reduces nitrogen excretion from tissue breakdown (anti-catabolic). The ratio of anabolic (muscle building) effects to androgenic (virilizing) effects is a common rating of anabolic steroids. Trenbolone has a high anabolic ratio. The anabolic ratio of Testosterone is 100, but the Trenbolone's ratio is 500.
