Stanazolol in water needs to be shaked well before using. I have never seen this product but many VET products use stanazolol because promotes lean mass so the animal gains muscles not fat+water.
I wouldn't use the product, i have never seen it, and i would never use any vet product. many use and get great results, but i consider myself human not animal and i would like to use human grade products not veterinary ones. veterinary products have lower sterility standards, if the cow loses one leg its not the end of the world but if you lose one you will definetly not be pleased.
