Beligas Trenbolone Enanthate 200mg Trenbolone enanthate or Tren E or TE is the longer Ester version of Trenbolone base that has a slow absorption rate and a half-life of about 10-12 days. This translates into a reduced peaking time and a longer time to be excreted from the system. While most athletes would prefer and opt for the faster absorbing Tren Acetate, it is Tren E that causes fewer sides and requires fewer needle pricks. For this reason, seasoned athletes looking for the optimum benefits of Trenbolone without the sides, often choose Tren E over Tren A during a cutting cycle. Availability and maintaining stable blood levels might be a concern though, especially for an inexperienced user. Trenbolone was administered to cattle to improve their feed efficiency. In simple terms, the cattle were able to better absorb nutrients from whatever food they consumed. And the result was a lot of jacked up cows. In humans though, Tren has a plethora of beneficial effects.
