CALM GOLD quickly helps with hot-tempered horse

Just a quick question.
Last week I started the CALM GOLD.
How long can you give this?
I am very positively surprised at how quickly this product works.
Not bought to “calm down” my horse, but rather because he can get very angry. Then he gets angry at his buddy (attacks him), at the dogs, etc etc
Moving a spike in the meadow could already be a reason for a rage attack. In other words, I had the impression that he was not feeling well mentally and I was right.
Now he is back in balance. No more angry outbursts because there is something mini mini he had in mind otherwise.
At work I don’t notice any difference in the sense of being sluggish or anything like that. Just relax.
With best regards
