Why You Feel This Way

Something changed
in your 40s.
This is why.

After 40, your body produces less of a molecule called NAD+. It's inside every single cell you have. It's what makes energy. It's what repairs damage. It's what keeps you feeling young. When it drops — everything slows down. Not because you're getting old. Because your cells are running out of fuel.

  • 😴 You wake up exhausted no matter how much you sleep
  • 🌫️ Brain fog that hits you by 2PM and doesn't let go
  • 🐢 Recovery from workouts, illness, or a bad night takes days
  • 🔋 You used to run on full — now you're always at 30%
  • 👴 You feel older than your age and can't explain why

The Industry Secret Nobody Talks About

If You've Tried NAD+
Before and Felt Nothing —
This Is Exactly Why.

An independent lab ran tests on over 100 NAD+ supplements sold on Amazon. What they found should make you angry.

76%Of Amazon NAD+ supplements failed to meet their label claims
57%Contained virtually zero detectable NAD+ — basically just filler in a capsule
0%Of Leep batches have ever failed independent third-party lab testing

"If you've been taking NAD+ supplements and feeling nothing, the most likely explanation is that the product you purchased contained little to no active compound. This is not a fringe concern — it is the industry norm on major retail platforms. The label means nothing without independent verification."

— Independent Supplement Analyst, 2025 Market Surveillance Report

Leep publishes its Certificate of Analysis. Every single batch is independently tested by a third-party lab before it ships. You can request the results. We have nothing to hide — because we put 500mg of real NAD+ in every capsule.

Why Leep Works

Two capsules.
Every morning.
That's the whole routine.

No complicated stack. No timing windows. No chalky powders. Just the molecule your cells need, delivered at the dose the research actually supports.

1

Take 2 capsules with water

First thing in the morning. The entire routine is 10 seconds. 500mg of verified NAD+ goes to work immediately — no conversion required, no efficiency loss.

2

Your cells start making energy again

NAD+ restores the cellular machinery that powers everything — your brain, your muscles, your metabolism. The fuel comes back on. Most people feel it within 48 hours.

3

Keep going — it compounds

Week one: energy and focus sharpen. Month one: sleep quality and recovery improve. Month three: you feel like a different person. The 90-day guarantee exists because we know it takes time — and we're confident it works.

150%Increase in cellular energy levels at 500mg/day — published research*

In a published clinical study, participants taking 500mg daily showed a 150% increase in measurable NAD+ levels within 8 weeks. No changes to diet. No changes to exercise. Just the supplement — at the dose Leep delivers.

What Changes

This isn't a supplement
that makes you feel different.

It's a supplement that makes your body work the way it's supposed to. Everything else follows from that.

Energy That's Actually There

Not a caffeine spike. Not a pre-workout buzz. Real, cellular energy — the kind that means you're still going strong at 4PM without thinking about it. The way it used to feel.

🧠

Brain Fog Lifted in 48 Hours

Most people notice the fog lifting within the first two days. Sharper. Faster. Actually present in conversations again. Words come back. Focus comes back. The version of you that used to be sharp at work — that person comes back.

💪

Recovery That Doesn't Ruin Your Week

One hard workout used to mean three days of soreness. One bad night's sleep didn't derail an entire day. NAD+ powers the cellular repair that speeds all of that up. You bounce back. Fast.

Look as Good as You Feel

NAD+ activates the proteins responsible for DNA repair and collagen production. People notice it in their skin first. Then in how their joints feel. Then in how they look in photos compared to two years ago.

How We Stack Up

Why pay $125/month for less?

The big names charge a premium for a single ingredient that still requires your body to do extra work. Leep delivers more — at a fraction of the price.
