I don't know if I am totally sure of what you are asking, however I will take a (wait for the pun) stab at it.
You will need alcohol swabs, syringes, and two different gauge needles. One gauge for drawing, like 18-20g, and one for injecting, like 23-25g. The injecting needles can be from one to one and a half inches.
Also, you will want to know the sites to inject and what to be cautious of, how to aspirate, why to do it, etc., etc.
Go look for some of the websites that have pictures on where to inject and all that. Something like this site http://www.****************/members/2thick/
