For helping children with deficiencies in HGH … yes.
For treating adults with deficiencies in HGH that would otherwise lead to decreased strength and bone density … yes.
To help a high-school or college kid beef up to be a bigger linebacker … no.
To help a professional linebacker keep up with other professionals … no … but for different reasons. They’re adults, and can do whatever they want to with their own bodies (as long as they are informed of the risks). But (a) as a lover of sport, it is (IMO) missing the point of what sports should be about; and (b) far more importantly, professional athletes are models for aspiring college and high-school athletes.
