you can use anything you want.
Whats to say your need to inject testosterone or take anadrol / dbol.
You could take anavar , peptides , run nolvadex alone, its fine to do it. You know your body better then us. Just because Girls run anavar doesn't make it girly at all..( stereotyping).
Run it if you would like to try it, its pretty safe and keep a journal of your workouts, how you feel, reps / sets / weights used etc.
Don't limit yourself on what you " SHOULD " be using. Trial and error is the best method for what your body responds to.. keep a log good luck and hope you progress further in your training
