Denkal is fairly good and Mike S and somebody else just had a post the other day about a new mexi company that just came out having a good product. But I've never had a problem with a denkal product.
The Denkall Aqua Test is a great product. it slides right through a 25g pin with no problem. The only thing is it is only a 10mL vial. I am using the new Sydgroup Suspension right now and it kicks ass. It doesn't clog my 25g pins and slides through nicely. It comes in a 100mg/20mL vial for around the same price or a little less depening on where you get it as the denkall Aqua test. But both a great products.
The best Ive used-Univet (20ml 100mg/ml). Hard to get and expensive. I have a few Denkall Aquatest and by all accounts it is very good and a smooth injection. Jurox sucks.
I tried Prolines oil bases suspension and I have to say that is the best I have used but going water susp, I wouldnt go with any other besides Univet or Denkall Aqua.....
