The science behind Revalor®-XR

Proprietary delayed and extended release technology delivers trenbolone acetate and estradiol in a unique way.

Revalor XR

Designed for steers or heifers fed in confinement, Revalor®-XR delivers the combination of trenbolone acetate and estradiol of a performance-based terminal implant in a single administration, thanks to its unique, delayed and extended release technology.

Each Revalor®-XR implant consists of 10 small pellets

  • All ten pellets are coated with a patented polymer. This creates a delayed and extended release product that takes effect 70 days after implanting, providing the benefits of a performance based terminal implant without the hassle of re-handling.
