Supplements:
For increased test I suggest the following: Viridex XT by Gaspari, D-Aspartic Acid (DAA) Caps, Animal Test from Universal (They also make a Animal Stak 2 which is good. Arimedex HD by BPI is good, more of a Anti-Aromitase though. Inhibit E is also pretty amazing, again more of an estrogen blocker. There is also a-50 by BPI and Prime by USP Labs. Both are on the fence for me.
I'm currently using DAA right now, the stuff is so sick. Super cheap too. I'm a bigger dude (217 lbs. 6') So I take alot of Protein and Amino Acids. One in the same, except I down the Amino's when I'm not eating, which is rare.
For Test, IGF-1 and GH increase I suggest full body workouts with emphasis on challenging compound movements. Strong stimuli in the form of Squats, DL's, PowerCleans amongst other exercises, produce noticeable gains in all hormone levels. Of course you're a bit older so some of these exercises have to be modified to accommodate individual body integrity. There is plenty of ways to stimulate the body when dealing with older clients.
Wait, you're not even that old, haha. Hopes all this helps. I'm sure you might have a few questions, so if you do I'll answer them.
