Garrick with NMN TMG berberine stack

The NMN Trust Test: Would You Give It to Your Mum?

What Garrick Felt After 2 Weeks on the Elite Performance Stack.

If you’ve looked at NMN and thought: this might be hype… you’re not alone.

That’s exactly where Garrick started.

He’s careful with supplements. He reads labels. He avoids fillers. He doesn’t trust glossy wellness marketing.

Before he ever ordered, he asked the questions you should ask too:
- What’s inside?
- Is it third-party tested?
- What about heavy metals?
- Will it stay stable during storage and shipping?

Then he tried our Elite Performance Stack.

About two weeks in, he told me he felt more energy.

But here’s the honest part: with NMN, some people don’t feel a dramatic “hit.” They often describe it as a quiet upgrade. They feel more like themselves. They feel steadier. Better overall.

This post is for:

- longevity beginners
- skeptics who don’t trust the industry
- gym people and high-output humans
- tactical athletes and military customers who care about readiness, recovery, and consistency

And I’ll show you exactly what’s in the stack, why we pair these ingredients, and how we handle transparency.

What Garrick did that most people skip
He didn’t “start with everything.”
He kept it simple, then stayed consistent.

A lot of people quit too early because they expect one obvious feeling in 3 days. That’s not how this works for many people.

**If you’re new, here’s the simplest way to start:**
1. Start with NMN (keep it simple)
2. Add TMG + berberine when you want the full stack
3. Stay consistent for a few weeks, then decide based on how you feel

What you might notice in the first 2 weeks (realistic expectations)

People report different things. Here are the most common ones I hear:

 1) More stable energy
Not a stimulant feeling. More like fewer crashes.

2) Better training consistency
More “showing up” days. Less dragging your feet.

3) Better recovery signals
Less soreness that lingers. Better sleep quality for some people.

4) Or… you feel nothing obvious
That can happen. Especially if your baseline is already strong.

If that’s you, track something simple for 14 days:
- sleep quality (1–10)
- afternoon crash (yes/no)
- training consistency (sessions/week)
- resting heart rate (if you wear a tracker)
- mood and focus (1–10)

Quiet changes show up faster when you track them.

Why we added a military and tactical athlete angle

We’ve had a lot of military customers over time.

That doesn’t surprise me.

This group usually cares about:
- repeatable routines
- clean labels
- consistency and supply chain
- products that are tested properly
- avoiding “mystery blends” and marketing nonsense

That is also how we think about supplementation.

No hype. No magic promises.

Just strong inputs, clean process, and clear labeling.

 The biggest problem with NMN is not NMN.

It’s the supplement industry.

You can find cheaper NMN easily.

But if you don’t know the purity, heavy metals results, and storage conditions, you’re guessing.

And with NAD+ precursors, stability matters.

How we approach transparency (what we do differently)

Here’s our non-negotiable checklist.

1) We list every ingredient with the exact dose
 No proprietary blends.

You can see the full breakdown here:  Elite Performance Stack

2) We publish COAs (third-party lab reports)
COA means Certificate of Analysis. It’s a lab report that checks what’s inside.

We look at purity, and we also test for heavy metals.

Here:  View our third party lab tests

3) We freeze-store for stability
This one is rare in supplements.

We store products below 7°C at our fulfillment center to support stability, and we’ve run a longer stability study because we take storage seriously.

Read it here:  Behind the scenes: why our process costs more

More detail:  Stability testing

 4) Our pricing reflects the real cost of doing it right
We spend less on flashy marketing.
We spend more on testing, storage, and stability.

Who this stack is for (and who should skip it)

 Good fit if you are:
- new to longevity and want a clean starting point
- skeptical and want proof before you buy
- training regularly and want more consistency
- a tactical athlete with a high-output lifestyle

 Skip or ask your clinician first if you:
- are pregnant or breastfeeding
- take medication for blood sugar, blood pressure, or clotting
- have a medical condition where supplement interactions matter

(You can always email us. I’ll reply personally.)

 If you want to go deeper: the science context 

NMN is studied as a way to increase NAD+ in humans.  
Berberine has human research around glucose and metabolic markers.  
Betaine (TMG) is well known as a methyl donor in human physiology.

 The simplest way to start (Garrick-style)

1) Take it daily as per label  
2) Keep it consistent for a few weeks  
3) Track 2–3 signals (energy, sleep, training consistency)  
4) Decide with real data, not vibes from day 3

If you want, reply to us with your biggest worry:
Purity? Heavy metals? Feeling nothing? Price?

I’ll answer personally, and I can send the latest lab report for the exact batch you’d receive.

Q & A 

What is the NMN + TMG + Berberine stack?


It’s a simple 3-part setup aimed at supporting:
- NAD+ pathways (NMN)
- methylation support (TMG)
- metabolic support (Berberine)

People choose it when they want a stack that makes sense on paper, is easy to follow, and is tested properly.

 What’s inside the Elite Performance Stack (exact doses)

We list every ingredient with the exact dose, because vague “proprietary blends” are a red flag.

 1) NMN (Liposomal NMN)
 **NMN: 500 mg** (daily serving on label)

NMN is a direct precursor to NAD+, a molecule your cells use every day for energy metabolism.

 2) TMG (Trimethylglycine) + methylation co-factors
Per daily serving on label:
- **TMG: 900 mg**
- **Zinc: 12 mg**
- **Folate: 900 mcg**
- **Vitamin B12: 30 mcg**
- **Vitamin B6: 5.1 mcg**

TMG is often paired with NMN because NAD+ pathways interact with methylation demand. Some people like to keep that side supported, especially when they’re stacking and training hard.

3) Berberine
Per daily serving on label:
- **Berberine HCl: 300 mg**

Berberine is used a lot in performance and longevity circles for metabolic support.

 FAQ 

How long does NMN take to feel?
Some people notice changes in 1–2 weeks. Others feel it more subtly over a few weeks. Tracking simple markers helps.

Why add TMG with NMN?
TMG supports methylation. Some people like pairing it with NAD+ precursors to keep that side supported.

 Is berberine good for training?
Berberine is mostly used for metabolic support. If you train hard and care about glucose stability, that’s often the reason people include it.

 How do I check NMN quality?
Ask for third-party testing (COA), heavy metals testing, and storage conditions. If a brand can’t show these clearly, walk away.
