The horse paste works just fine. For a long time, that's all that was available. Both my daughter and I have used it. Be sure to read how many lbs. per notch, because it can vary quite a bit between brands, and adjust it to your weight. We did the one dose based on our weight. That knocked it right out, almost immediately. I have other friends that have done the same, and they reported the same results. PS. In our experience, the apple flavored tasted worse than the non-flavored.
For the record, almost all medications are tested on animals first, so the veterinarians get first crack at the human meds. In many instances it's the same manufacturer for both human, and animal meds. The manufacturers just crank it out, and the only distinction is whether, at the end of the line, they put it in packaging for humans, or for animals. The problem that arose with purity, was due to branding. Because animal meds are not strictly regulated, several brands were obtaining the pure product, then adding some extra fillers, increase their profit margins, and rebrand it. Most of the top name brands have not done this.
