THE ORIGIN

Why this drink exists.

A few years ago, a small group of elite athletes and operators kept running into the same problem: every "clean" energy drink on the shelf still had ingredients that could trigger a positive on a sanctioned drug test. Proprietary blends. Mystery stimulants. Unverified sourcing.

Coffee worked but didn't last past hour two. Pre-workouts were a non-starter. The classic OGs and big-can stims were full of sugar and questionable ingredients. The only viable option was nothing — which meant 16-hour shifts and grueling training blocks fueled on willpower alone.

So we built one. Informed Sport Certified. Every batch. 249mg of caffeine (175mg green tea + 74mg di-caffeine malate) plus our cognition + endurance stack (Lion's Mane, Alpha-GPC, L-citrulline) — engineered to time-release across four hours instead of spiking and crashing. Zero sugar. Zero shortcuts.

We weren't trying to build a beverage brand. We were trying to solve a problem for people whose careers depended on what they put in their body.

Then word got out. And here we are.

01

Informed Sport Certified

Every batch. The only energy drink elite athletes and operators can drink without risking a positive test.

02

Time-released caffeine

Engineered to release over ~4 hours. Usable focus from minute 20 to hour 5 — no spike, no crash, no afternoon collapse.

03

Two caffeine sources, dosed right

249mg caffeine: 175mg from green tea (natural caffeine + L-theanine) + 74mg di-caffeine malate (slow-release). Plus Lion's Mane and Alpha-GPC (nootropics) and L-citrulline (endurance amino acid). Every ingredient named at clinical doses — no proprietary blends.

Athlete-trusted

"I've never had an energy drink that makes me feel energized and ready to attack a workout that also has prolonged performance benefits. The blue raspberry flavour is also unbeatable in my books."

What people are saying.

★★★★★

"I work overnight shifts and used to chug two 300mg-spike drinks. My hands stopped shaking the week I switched. Energy is steadier, sleep is better, no crash."

— Eddie M., ER nurse

★★★★★

"I compete in a tested federation. This is the first energy drink my coach approved. Tastes great, holds up through a 3-hour session."

— Jess R., powerlifter

★★★★★

"Patriot Pop is genuinely the best-tasting zero-sugar drink I've had. Doesn't taste 'healthy.' Hits like a regular energy drink but feels different."

— Anthony D.

Quick questions.

What does "banned-substance tested" actually mean?

Every batch is independently tested for substances banned by WADA, USADA, NCAA, MLB, NHL, NFL, and the major military/government regulations. We publish the cert.

How much caffeine?

249mg total caffeine, time-released over ~4 hours from green tea extract + di-caffeine malate. Full breakdown printed on every can.

What gives it the calm-focus feel without jitters?

Green tea brings natural L-theanine and antioxidants. Di-caffeine malate releases slowly instead of spiking. Lion's Mane mushroom and Alpha-GPC support cognition. L-citrulline supports endurance. Real ingredients, real doses, named on the can.

Is this a pre-workout?

No. It's an energy drink built for sustained focus through a long day, not a 60-minute training session. Lower caffeine, longer curve, no beta-alanine tingle.

Money-back guarantee?

30 days. If it's not the best energy drink you've had, full refund. Keep the empties.
