I'm not even sure if HGH is a better solution for cardio/strength over AAS. HGH helps repair tissue and aids in recovery. Well, that's been my experience. I can just stay stronger for longer after an AAS cycle when I'm on HGH. I like HGH's ability to put on lean muscle, more like a physique competitor, over a bodybuilding competitor. Definitely help enhance performance but it does it slowly over time. Definitely does NOT replace hard training.
