What needles/kit should I be using?

Just got my first script today and going to be using these single 200mg doses weekly. Unfortunately the medication did not come with needles or additional instructions. What kind of needles do I need? Where can I buy a kit? Thanks in advance for all of y’all’s knowledge!
