Easy to use
October 18, 2020
VetPen arrived quickly within 2 days of shipping, along with a few insulin cartridges. Instructions for using are easy. A lot cheaper than other pet pharmacy sites! Would recommend trying if you have issues handling a traditional syringe.
Depending on your pet’s dosage amount, you may end up wasting some insulin if the last of it in the cartridge isn’t enough for one dose.
