You don't want to compare 47 ingredient labels. You want results. Clann13 builds science-backed performance stacks around one outcome — delivered monthly, dosed right, priced fair.
Three questions. We match you with the exact stack built for your goal — not a generic vitamin pack. No email required to view results.
SELECT ONE — WE'LL DO THE REST
Built around what you actually want. No padding. No filler products. No "buy 12 things to figure out which one works." Each stack ships with five full-size, USP-grade products.
Fat loss, lean energy, no crash. Pre-workout fuel + post-workout repair.
Methylene Blue + nootropics. Mental sharpness under fatigue. Decision fuel.
NAD+, Lion's Mane, cellular repair. Age well. Train longer. Recover faster.
Skin, hair, gut, hormonal balance. Beauty from the inside, not a $90 serum.
Creatine + hydration + BCAAs + recovery. The complete training system.
Built for tournament weekends, contact recovery, back-to-back fixtures.
Performance isn't a one-time purchase. Your stack ships monthly, dosed for your goal, at half the retail price of buying it piece by piece. Cancel any time. No hidden fees.
Rugby, football, MMA, wrestling, CrossFit. We started with rugby because no brand owns this lane. Now we're stacking by position and discipline.
Strength, power, scrum work, contact recovery. Built for the engine room — props, locks, hookers.
Sprint, endurance, agility. For wings, centers, and athletes who run for a living.
Repair and readiness. Tournament weekends. Back-to-back fixtures. Bruises don't stop matches.
