The science behind Revalor®-XH

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


Designed for heifers fed in confinement, Revalor®-XH delivers the combination of trenbolone acetate and estradiol of two-implant programs in a single administration, thanks to its unique, delayed and extended release technology.

Each Revalor®-XH implant consists of 10 small pellets

  • The first four pellets are uncoated, which allows them to go to work immediately after implanting.
  • The other six pellets are coated with a patented polymer. The delayed-release pellets take effect 70 days after implanting, providing the performance of a moderate potency terminal implant without the need for reprocessing.
