It's the same stuff 100%
So to get out of govermewntal guidance they change the name to sinoquin.
What they could do is refuse to sell this at such overinflated price when they know the product is available in Asda for £2 a bottle.
Profit is healthy to a business as it's the end result of the business model.
Nothing dirty in profit..Unless your taking the piss with your customer base which is what they are doing with this product mate.
The price for the vetinary supplies will be totally different to the price for human supplies. It is not as simple as you are claiming it to be. Why not talk to a vet and ask them to explain it to you. If you are expecting a vet to go through the entire chemical compounds of every single drug they ever dispense to make sure there's not the slightest difference in them, then you're going to be disappointed. They're vets, not omniscient pharmacists.
I get the frustration, but expecting the vet to know all the ins and outs of every single treatment, for every single animal they ever see, is not going to happen, ever. You did your research, and that's the thing to do.
