The fish that
does not stop.
Skipjack tuna — katsuo — spend their entire lives in motion, cruising at speeds up to 60 mph. They never stop. They never tire.
We took what nature evolved over millennia and packaged it into a capsule — so you can carry a little of that into your next session.
Bonito Peptide
Concentrated from wild skipjack. Two capsules carry the active peptides of roughly 1.5 kg of bonito.
Lactate Clearance
Less burn, less heaviness — so you can hold pace deeper into the effort.
Lower Heart Rate
A quieter cardiovascular signature during high-intensity work — the same output, with less strain.
Blood lactate, measured.
Five professional running coaches. Treadmill. Seven 3-minute stages, each faster than the last. With bonito peptide versus without. Blood lactate (mmol/L) was lower at every intensity.

For the quietly
relentless.
One follow-up at the Yokohama Sports Medical Center logged a quieter cardiovascular signature at every running speed — heart rate down 33 bpm at LT pace versus the prior test. Same subject, weeks apart.
