I bought a different brand but that one looks good.

You'll find a plastic syringe inside the box with notches on the plunger based on horse weight. Based on the average weight of a healthy adult, each syringe contains roughly eight doses. Use your wight and squeeze out one dose onto a spoon (probably a dose half the size of the top joint of your little finger) and eat it.

Pop the plastic cap back on the syringe and keep it until you need it.

The paste is white like hand cream and tastes like what I imagine hand cream tastes like (not unpleasant but not yummy either).

Read the box packaging storage instructions because most brands need to be stored below 80F / 25C. I keep mine in the fridge.
