I was wondering if HGH or certain peptides cycles would help aid in a military type fitness? Now I know you can pack on some size, but I'm looking for more solid, lean, and strong build and maybe even keep the joints and overall health better?

My goals are to increase power, muscular and cardiovascular endurance, and frankly, to just be a real meat-grinder out there. Basically help me get my mid-range running (2-5 miles) faster, become physically stonger, and aid my bodyweight/endurance weightlifting.I feel like there aren't too many anabolics that fit my goals as well or that do not give some insane pump that hurts cardio. Plus from what I have read, there are much less chance of side effects here, plus the boost in overall health and well being seems like a nice perk. Trying to peak my overall fitness.

Here's me:
5'11" and 190 pounds
just about 26 years, training hard since high school
body fat 11%
5K: 19min 30sec
bench/squat/dead: 315/435/465
I exercise a lot: lifting, crossfit, wrestling, running, and anything else you might think of.

Won't be down range for a while, so that is no issue. Thanks for any help guys, I appreciate and knowledge thrown my way!
