Go past where
you used to stop.
A performance stack that fights the three limits of endurance — muscular burn, restricted blood flow, and running out of fuel. Made in Canada, lab-tested every batch.
Three drivers of aging. One daily system.
Aging isn't one problem — it's three. Each supplement in this collection targets a specific, well-studied mechanism so the stack works as a whole.
The burn
That deep muscular burn is acid building up faster than you can clear it. Beta-alanine raises carnosine — your muscles' built-in buffer.
Restricted flow
Working muscles need oxygen in and waste out. Nitric oxide support keeps the vessels open and the exchange happening.
Running out of fuel
Long sessions drain glycogen — and when it's gone, pace goes with it. Fast-clearing carbs and hydration support keep the engine fed.
Raise your burn threshold
Beta-alanine is one of the most-studied performance supplements in existence — it builds muscle carnosine, buffering the acid behind the burn so you hold pace longer before fatigue wins. (The tingle is normal.)
Keep the pipeline open
Citrulline malate feeds the nitric oxide pathway that widens blood vessels, and GPLC pairs carnitine with glycine for circulation and fuel-use support — more oxygen in, more waste out, every minute you're working.
Fuel that doesn't fight you
Highly branched cyclic dextrin clears the stomach fast and delivers steady carbohydrate without the gut distress of sugary drinks. Taurine supports hydration and muscle function while you sweat.

Loved by Canadians who go long
A winter of consistent training plus this stack, and my half-marathon PR dropped six minutes. The cluster dextrin ended my mid-race gut issues completely.
Beta-alanine changed my third periods. Legs that used to be gone by the 12-minute mark still have jump. Whole beer league's on it now.
Cluster dextrin and taurine in my bottles, citrulline before. Finished my first 160 km ride feeling strong instead of surviving.
