I actually took some two days ago. Green apple flavor paste I bought at TSC. I feel a lot better. The only side effect so far was a temporary partial blockage of vision as a worm in my right eye that I didn’t even know I had was dying. The trick is not to overdose. I’m a 250lb man and I only took a half dime size amount.
It’s actually pretty safe. It has a high overdose level in horses. Horses are very sensitive critters and you would really have to overdose one to even make it sick. I have ingested it many times. Not on purpose of course but trying to get the paste into some goober’s mouth. I once got half of a 1200 tube in my mouth. Ended up swallowing most of it. I didn’t get sick. It is really a great drug for lot’s of external parasites and such.
