Good to know!
I had bought some Durvet at the tack and feed store a while back, but was not looking forward to trying to compound it into 15mg doses for a 200# human, as opposed to a 1,100 pound horse.
It is recommended to empty entire syringe and use some type of coloring agent (food dye?) to mix the product. Someone said the product in the existing syringe is not uniformly mixed.
Just saying.
