Regu Mate (Altrenogest) 1000mL

$161.95 available on subscription

You can help reduce undesirable changes in behavior and mood by suppressing your mare’s estrous (heat) cycle with Regu-Mate® (altrenogest). Within three days of the start of treatment, Regu-Mate will effectively suppress estrus in 95 percent of mares.

It’s important to note Regu-Mate cannot improve your mare’s performance from what it is normally. Regu-Mate can only eliminate hormonal distractions so she can focus on you and perform more predictably.

Regu-Mate the proven performer for performance mares

When you’re campaigning a mare, every advantage counts. That’s why more and more trainers are turning to Regu-Mate to suppress estrus and make their mares’ performances more predictable.

Regu-Mate effectively suppresses estrus in 95 percent of mares after 3 days of treatment.
When treatment is discontinued, mares exhibiting regular estrous cycles return to estrus within 4 to 5 days following treatment and continue to cycle normally.
Regu-Mate can help alleviate moodiness and temperament changes associated with estrus.
It’s easy to administer – orally or top-dressed on grain.
Talk to your veterinarian about proper use and safe handling of Regu-Mate. Avoid skin contact. Always wear protective gloves when administering Regu-Mate. This product is contraindicated for use in mares with a previous or current history of uterine inflammation. Pregnant women, or women who suspect they are pregnant, should not handle this product.
