Kisspeptin-10 pre filled cartridge pen

im thinking of using kisspeptin-10 5mg pre filled cartridge pen on my rat for research and ive read you have to have to prime it first, but after that what number on the dial should i start with on the dial, and how many times per day and how many days a week..and how many weeks to use it on my rat before cycling and how long to cycle it so my poor unhorny rat becomes desensitised...im a research virgin and any help would be much appreciated because my male pet rat is feeling down..
