I'm 19, 6'2, 190. Reta and Ghkcu are what I'm looking to get started with. My training runs on a PPL X UL split, with weekends off. With Reta, the aim is dropping the fat that sits on my face and lower stomach. Ghkcu is only for getting my hair to grow more. Where to begin and how to go about it isn't clear to me yet, so any pointers would be welcome.
