Drostanolone Propionate

The acetate ester is a very short-chain ester attached to the Finaplix molecule. It has an active life of 2-3 days but to keep blood levels of trenbolone elevated and steady, daily injections are often recommended. The acetate ester provides a rapid and high concentration of the hormone which is beneficial to those seeking quick gains, coupled with a rapid clearing time the acetate ester can be discontinued on the onset of adverse side effects.

Ironically, even though Trenbolone ( Tren ) is an excellent contest prep drug, it lowers your thyroid level(23), and this raises prolactin. I recommend taking T3 (25mcgs/day) along with your Tren to avoid elevating your prolactin too high via this route.

Also, this drug is a poor choice for athletes who rely on cardiovascular fitness to play a sport. Trenbolone ( Tren ), anecdotally at least, reduces many athletes ability to sustain high levels of endurance. Unfortunately, this makes Tren a poor choice for many.
