I have a lot to add to this and its interesting.
Ibutarmoren - I have used the liquid version of this hgh secretion drug for 2-3 years on and off, makes me stronger skin better but hungry as, hair wise I have never really noticed any benefits, but I took sub-q hgh back in 2012 before I had any hairloss, and my hair was the best quality I have had in my entire life.
Ostarine - I started loosing my hair mild thinning very slow, but this drug made my hair grow much thicker and new hairs started sprouting almost as good as when on hgh, I then added finasteride to the mix and boom my hair was ridiculous.
