Yeah, that's why you have to buy it from China, where they use trimethoprim by the trainload, since it increases the efficacy of one of their most
popular livestock antibiotics. Some suppliers won't even sell less than a metric ton, and it's commonly sold between $5-$10 per kg if you buy it by
the drum. Lots of interesting chemicals can be found quite cheaply from Chinese suppliers, especially if they're needed to manufacture something that
China makes a lot of. And they make a lot of just about everything. |
