Beta-Alanine products provide some nice, sustained
endurance. Not a noticeable
energy boost, but it's a solid staple supp that helps keep you stronger longer, if that makes any sense.
Green Tea Extract is a good choice too. It's a nice antioxidant, and also gives a clean, natural
energy boost. I think NOW has bottles of caps for like $7 or $10 here on BN. Pop 1 with breakfast and 1 with lunch and that should be good. Pop an extra if you need a boost.
