Genotropin info please

Iv found a source to get a prescription for a hrt does I'm having bloods done in 2 weeks and Iv been told they would prescribe someone of my age,28 a Pen a month is that enough to grow my hair back I'm receding from past steroid use and it's in the family I'm not trying to get huge I have just aged a little fast due to health problem and want to look younger etc I have zero knowledge on the stuff and would like any advice
Safe dose?
How long until hair grows?
How much on average a pen is worth?
Anything really if I was to grow my hair back I would think about doing a primo 100 with hcg during and novladex coming off does this sound silly or what I just want least side effects as possible to hair that why I have decided primo 100 would be the good choice.
