I still have two tubes of horse paste in a drawer, along with the calculated dosages for my wife and me. Still haven’t caught Covid, but we’ll probably use it if that happens and if it’s worse than an ordinary cold.
Just a note, the stuff tastes awful. Take it in a spoon with peanut butter if neither of you are allergic. It does a great job helping to mask the taste, but it’s still there.
Why not take the tablets? You can get them in 3, 6 and 12 mg dosages.
