While athletic supplements can be as crucial to performance as shoes and properly gripping underwear, you don't want a drink that's gonna leave you so jittery you end up running into a tree, or police caution tape. Up your game to FRS.
Endorsed by legions of trainers and a guy who's been known to occasionally train (Lance Armstrong), FRS is a healthy energy drink packing 1/2 the caffeine of coffee, and all of the staggering potency of quercetin -- a fatigue-fighting antioxidant found in apples, raspberries, red onions and, of course, the Uncaria plant of Brazil. The deal: quercetin works as an enzymatic block that allows the energy your body naturally produces to stay in your system far longer, while also boosting your immune system and reducing inflammation. In a poll of supplement-savvy customers, 90% found FRS superior to everything else on the market, such as Monster, Red Bull, and Rockstar, though to be fair, Peruvian "frog smoothies" were not up for consideration. Because everybody's got their something, the good stuff's available in can, concentrate, powder, or chew form (sorry, people who love inhaling things).
Because staying fit shouldn't break the bank, today only FRS is offering a free trial special for the first 500 Thrillist readers to respond: basically, a $50 sampler of the FRS products (plus a free, arse-kicking, eco-friendly water bottle) for just the cost of shipping. Such savings you can put towards other athletic necessities - like an inspirational Brian Bosworth "Wizard of Boz" poster, and some fresh properly gripping underwear to replace the ones you soiled frantically fleeing the cops.
