Yes. Even top-level athletes benefit from faster lactate clearance and improved recovery. As you level up, Katsuo Stamina helps you stay consistent and avoid plateaus.

It’s better not to. Take it with water to avoid absorption interference.

Yes — it’s used by top trail runners, cyclists, and even MMA fighters across Japan, Malaysia, and Singapore.

Yes — it’s packed in resealable slim sachets that are waterproof and heat-resistant.

Each sachet has a shelf life of 24 months from the production date. The exact expiry date is printed on the box and each sachet, so you always know it’s fresh and safe to use.

Cool, dry place. Room temperature is fine — avoid direct sunlight or humid environments.

If over 16 and actively training, yes. But check with a coach or nutritionist for younger users.

Of course. It’s beneficial regardless of gender — especially during high-intensity training weeks.

Yes. In fact, the older you are, the more benefit you’ll feel in recovery and stamina.

Yes — great for easing into training without burning out early.

Not at all. If you sweat, push yourself, or want better recovery — Katsuo Stamina can help you.

If you have a seafood allergy, avoid it. Otherwise, it’s safe.

Yes — it has no carbs and is fully keto-compatible.

Technically yes, because it contains amino acids. But it’s light enough to be used before a fasted workout without causing insulin spikes.

Mild umami. It’s not sweet, not bitter — just neutral enough to mix into your hydration without changing the taste.

Yes — athletes with sensitive stomachs report no bloating, no discomfort. It’s one of the cleanest endurance supplements available.

Nope. It’s completely stimulant-free and sugar-free.

No pork, no alcohol — Halal certification in progress.

No — it’s made from bonito (katsuo), a type of fish. It’s pescatarian-friendly, but not vegan.

Zero. It’s WADA-safe and suitable for competitive athletes.

es. Made from natural fish peptide extract — no fillers, no sugar, no artificial colors, and no banned substances.

Either works. For best results, take on an empty stomach before training or 15 minutes post-session.

Yes. It stacks well with electrolytes, BCAAs, protein, creatine, or endurance drinks. Just avoid overlapping too many amino blends.

No loading phase needed. You can start taking it right away and feel benefits within the first few uses.

5 sachets (10 dose) max daily. Space them based on session demands — 4 tablets before and 4 tablets after workout or split between back-to-back sessions.

No. There’s zero caffeine or stimulants. It delivers smooth performance without crashes or jitters.

Yes, especially if it’s an intense pace or involves bursts of effort like a 10K or sprint triathlon.

No — it’s not an electrolyte product. Take it with 200-300ml of water or pair with Elec Stamina during races.

It’s made for that. Long durations lead to lactate accumulation and muscle breakdown. Katsuo Stamina gives you an edge in endurance and recovery when you’re hours deep.

Yes — it’s race-day ready. Consume 4 tablets every 90–120 mins depending on race intensity and temperature. Many trail runners take one before the climb and one near the final hour.

Yes. Protein helps rebuild muscle. Katsuo Stamina complements that by enhancing recovery from a metabolic angle — they work best together.

It works differently. Ice and massage treat soreness after it happens. Katsuo Stamina reduces the source of fatigue from the inside — lactic acid buildup.

Yes, especially if you lift high reps or do endurance-focused strength sessions. It supports muscle recovery even when lifting weights.

It helps minimize delayed onset muscle soreness by protecting muscles from excess lactic acid accumulation and aiding recovery.

The peptides promote enzymes that convert lactic acid (lactate) into pyruvate — which the body can use for energy. This process helps you keep moving even when others slow down.

Yes. In shorter, intense efforts, it buffers lactate spikes. In longer runs, it sustains energy and protects muscles over time.

Absolutely. It’s particularly useful in tough terrain or when elevation causes lactate to build fast.

It doesn’t replace proper training, but by reducing fatigue and enhancing recovery, you’ll be able to train harder and smarter — indirectly pushing your aerobic capacity higher.

Yes. Users report they can sustain pace longer without hitting the “wall.” It keeps muscles firing efficiently even in the final push of a workout or race.

It reduces fatigue by helping your body reuse lactic acid for energy. That means less muscle burn, better stamina, and improved performance — especially during hard intervals or long sessions.

Hydrolyzed Katsuo Peptide — a fish-based amino acid profile that supports metabolic recovery and endurance.

Yes! Whether you’re running ultra marathons, cycling, training CrossFit, or doing long hikes — if endurance and recovery matter, Katsuo Stamina helps.

Most products only mask fatigue. Katsuo Stamina addresses it at the source by targeting lactic acid metabolism. It doesn’t rely on stimulants, caffeine, or sugar. It’s clean, natural, and used by elite athletes for long-term results.

Both. It’s versatile. Take it 30 minutes before training to improve endurance, or immediately after to reduce lactic acid and enhance muscle recovery. Many athletes use it for both — especially during race day or back-to-back training.

Katsuo Stamina is a performance and recovery supplement made from premium-grade Japanese katsuo (bonito) peptides. It helps your body recycle lactic acid—meaning instead of it causing fatigue, it gets converted back into usable energy. This reduces soreness, boosts stamina, and supports muscle recovery.
