Suzanne Brons, owner Flip & vet

I have already been through a lot with my horse, Flip, an almost 9 year old KWPN gelding. For a long time I suspected something was bothering him, but we couldn’t find it. I (am a veterinarian myself) and my colleagues have checked a lot but found nothing at first.
In the meantime you muddle through. A horse that works hard for you one moment and buck so ugly and unexpected the next that it seems as if he just wants you off his back. After a long search he turned out to have an injury to his SI joint. He was treated for this, I am now also a graduated chiropractor for animals and I can support him well with these treatments. Trying Equi-Syn seemed like a very valuable addition to this. (…)

Dressage stable Luna e Nero

My Grand Prix mare LN Tiadette had an unclear injury a few months ago. After several visits to the veterinary clinic, there was no clear diagnosis and rest alone did not seem to help as she immediately relapsed into a slight irregularity after a little more exercise. The treated vet suspected an injury to a strap in the lower foot
On the advice of Dr. R. van Dokkum I then started using Synopet Equisin. We first had to use this for 10 days and then see how it went. After this I took her back into training lightly and she remained good after a little more exercise. Of course I was very happy with that! (…)

Bianca Walet, owner of Fries Bas

More than 2,000 euros in costs to get Bas back on his feet, but no result whatsoever. A lame and stiff horse.
The Equi-Syn boost has done him unbelievably well! We are now driving again.
