Univet suspension is no longer made, Univet still has an active license for the veterinary suspension and prop but they no longer produce it, you can contact them and they will tell you so.
That being said the bottles floating around are a high quality knock off and the gear inside is in actuality test suspension so it is good to go. The stuff flows through a 25g with ease. The real univet suspension from back in the day use to clog a 23g and hurt like a SOB.
