Read this first
No human pharmacokinetic or safety study exists for this compound. Everything below the mechanism is community report, and the cardiovascular effects reported are more severe than for any other entry here.

How it works

Binds the androgen receptor with much higher affinity than testosterone and is not aromatised. It is also a potent progesterone receptor agonist, which accounts for a good deal of what people report from it.

Intramuscular

In the body

No plasma curve is shown for this compound.

Unmeasured in humans. Trenbolone was developed as a veterinary implant and has never been through human pharmacokinetic study, so there is no half-life to quote and no honest curve to draw. The acetate ester is short, and injections are typically daily or every other day on that basis alone.
