Bad packaging - should be zero stars

I called about this & problem was not corrected! This product is a liquid hormone for horses. It should not be handled by women! The seal on the lid of the bottle

I called about this & problem was not corrected! This product is a liquid hormone for horses. It should not be handled by women! The seal on the lid of the bottle was dislodged & the liquid spilled out, soaking the box & my front porch. And it got all over my hands when I picked it up before realizing it had soaked through. I called regarding this problem & explained that the bottle should come inside of a plastic bag to prevent this! I was told that they could bubble wrap it for me, not as good as putting in a sealed bag, but better than nothing. My replacement arrived without the bubble wrap or bag. This product should not be handled by women & I was forced to clean it from my porch. I expected better care from chewy! Very disappointed.

Able to help her with her cycle issues

Keep her quiet and not kicking walls, less painful cycle for her, help keep her focused and more tuned into her training program.

It's helping

This is our 4th week. She is much nicer to me, and other horses. I did have to do some research to figure out how on earth to administer with out getting it on

This is our 4th week. She is much nicer to me, and other horses. I did have to do some research to figure out how on earth to administer with out getting it on me. Buy 10cc syringes. They screw on to the bottle. Turn the bottle upside down and pull syringe plunger to get the desired dose. Of course wear gloves. Then plunge into horse mouth. It must taste ok because she does not resist at all.
