Perfect Harmony EQ from Perfect Products uses nutraceutical ingredients to naturally mimic the relaxing and behavior-related effects of Progesterone therapy. Hormonal imbalance can negatively affect a horse’s behavior and performance. Perfect Harmony EQ supports balanced hormonal functions to help curtail hormone-related aggression, agitation, or sullenness. This quick-acting supplement may lead to improved behavior in as little as 2 days after the first dose and continues to strengthen with daily use. 

Perfect Harmony EQ does not contain prohibited ingredients or require drug reports for use at competitions. This top dressing liquid can be added to the horse’s grain and is safe for humans to handle. This supplement can also safely be combined with other Perfect Products calming products such as Perfect Prep EQ.

Amazing results, within 3 days!


My mare gets this with the perfect training day supplement. The training day was great, but she was still not completely focused on me and would throw “tantrums” (like at shows if I was giving another horse attention, showing another horse, at home if I was riding another horse before her, or if she sees me packing and hooking up for a show- she squeals, paws, bucks, rears, and then throws herself on the ground. Which usually gets my anxiety up. It reminds me of a naughty kid in the grocery store going limp and throwing themselves on the ground). This supplement has stopped her tantrums. Per the directions, you should see results within 3 days and it was true. She is way less spooky and much more focused on me while riding. If I’m going to a show, I will give her an evening dose, but she is maintained on just the morning ounce. I would suggest this to anyone who needs a little more out of their calming supplement. It has really made a huge difference for my mare!

Effective supplement!


A wonderfully effective feed thru product to help manage behavior.
