pre-workout your own

Can't find a good pre workout make your own. this one has stuff to not lose muscle
give more not a lot testosterone and NO for that pump.
No garbage.
I research supplements and then come up with the best combinations for me I'm 62 at 40 everything started to go down hill.
screw that I'm just getting started kids are grown life is starting to get fun.
the stuff I do and look at if some one younger did it it would increase by 10.
your not worried about it when your younger but start now or start over when your old. http://oldmanhealth.com/
