I purchased this to administer a tube of Probios. Works great and makes it easy to control the dose.

An applicator gun was recommended by friends when they recommended I use Replamin plus. I didn’t have money at first and used a syringe to dose them. They were chewing the syringes! This gun is a little big for my not so big hands and arthritis, but it turns giving supplements into a 5 minute job! It also fits other large tubes like Probios. TSC has the best price! If you have been hesitating, I say “jump in and make this job easy, and your supplements less expensive by buying in bulk!”

Works great if you can understand how to use the pin and the hole for the different cc available on the gun. there's no- hey I'm new to this instructions so at the moment I'm doing some on the amounts.
