Fred, it’s not over-the-counter; Jane long had to get a prescription.
That’s why people are buying the horse paste.
And some feed stores have signs in front of the cheap brand ($3.99) saying ‘not for human consumption’ and the cheap brand is sold out.
No sign in front of the more expensive brand ($9.99) though.
I don’t understand why ‘people’ hesitate to buy from the link I provided. It’s a buy-on-line purchase just like any other. No prescrition required. Dose is clearly shown, it’s not a fly-by-night company. You order by email, they forward, it cleared customs in both Australia and Canada that I know of.
