Question about hypodermic needle/syringe laws in Texas

Can anyone point me in the direction of where this is? I've looked in the law book for the boards and even online at the state board of pharmacy's website but I have had no luck. I've been told that they need proof of insulin use in their medication profile, but I would like to see the law myself regarding quantities we are allowed to sell, if we need to ID, age restrictions, etc.
