Our standard

Peak is a
rhythm.

Not a moment. Not a hack. A body that trains, fuels, recovers and sleeps on time, day after day.

Why we exist

The supplement aisle is loud. We'd rather be right.

Performance nutrition is full of big promises, hidden doses and ingredients that were trending last month. Technical apparel is full of fabric names that sound like science and aren't.

PEAKfreq is built the other way round. We start with the research, the position stands, meta-analyses and randomised trials, and only make what holds up. Then we grade it, publish the references, and tell you when the evidence is still early.

We call it frequency because physiology is rhythmic. Heart rate, stride cadence, sleep–wake cycles, neural focus and tissue repair all run on cycles. Performance is keeping those rhythms on time, and every product we make is built for one of them.

Cadence

Stride, stroke and pedal rate

Cellular

Muscle and tendon repair cycles

Circadian

Sleep–wake clock

Neural

Beta-band focus

Cardiac

Heart rate & HRV

Four principles

The standard.

01Evidence over hype

If the human research isn't there, we don't sell it. If it's early, we grade it C and say so on the front of the page.

02Dose disclosed

No proprietary blends, ever. Every active is printed with its amount, and it's the dose used in the research.

03Claims we can defend

We only make the health claims regulators have authorised. Everything else is research, clearly labelled as research.

04Built to last

Recycled and traceable fibres, mono-material packaging, and outerwear repaired for life. Performance shouldn't cost the mountain.
