Can you stay
sharp at your
summit?
Play the quick 60-second focus test, reveal your Peak Type + Focus Score, and see what keeps you performing at altitude — when the pressure is highest, not just when the day is easy.
Apexspan runs on Numin — a once-daily mental-clarity drink that tastes like lemon iced tea. No caffeine, so there's no spike-and-crash. You just notice the fog doesn't roll in when you need to keep climbing.
Hold the summit in mind
The cards flash face-up for a few seconds. Lock them in — then they flip and we'll ask you to find one. This tests the exact mental hold that slips first when you're running low near the top.
Building your Peak Profile…
The Base-Camp Fader
Here's the part most people miss: near your summit your brain isn't just tired — researchers describe it as depleted from the thousands of decisions you've already made on the climb. The good news is that this is one of the more addressable patterns.
It's called decision fatigue
You make tens of thousands of small choices a day. Each one fires glutamate in the prefrontal cortex. When it builds up faster than your brain clears it, focus slips, choices get harder, and the wall hits just as you near your peak. These are the 5 signs:
Picking the easiest option instead of the best one.
Putting decisions off until the pressure builds.
Reacting impulsively instead of responding thoughtfully.
Letting someone else make the call for you.
Sharp early on the climb, foggy and slow near the top.
The conventional fix is more caffeine — but coffee wakes you up, it doesn't help your brain clear the buildup. That's the gap the next step targets →

"What sold me: the founder has a PhD and actually publishes. Not a celebrity-backed brand — the formulation reflects that."
"Stimulants spike my anxiety. This doesn't. An actual solution that doesn't leave me wired."
"I'd been burned by energy supplements before. This isn't about energy — it's about staying mentally sharp. Six hours in, no jitters, no crash."
