The man is retired, so preumably he is with us in his sixties.

60's means nothing. I'm 56 and I teach an intense 3.5 mile boot camp every morning including P90X exercises.
Zinc, Magnesium, DHEA are all good over the counter remedies.
I also use IGF-1 or deer antler extract. The stuff works! Ask VJ Singh, Tiger, Ray Lewis, Diego Sanchez and a host of other sports figures. It's natural, over the counter and been studied to not have any side effects. In fact, insulin users have been proven to reduce the need for insulin using IGF-1.
Take your supplements at night before bedtime which is when your body historically produces all it's growth hormones.
Clean up your diet, loose the gut (over 38" waist is a death knell for your d!ck), get off the booze and increase your cardio. Cardio gives you better blood flow and endurance.
I'm a big proponent of natural health but would definitely like to "supplement" my test levels. I tried the patches for 90 days -- amazing results with mood, skin, hair, nails, sleep etc -- but they were cost prohibitive in the USA at $300 per month.
I'd bet the creams work just as well.
There's side effects to everything, but the way I see it, at this stage of the game, no risk = no reward.
One thing's certain, if you're sitting on your arse drinking Presidentes and Brugal most of the day looking at beauty, you'll not have the energy or juice to chase it.
