Clark Pentico, 50 – Marathon Runner

I am 50 years old, have run several marathons (including Boston), have run triathlons,
half marathons, I have even run the Grand Canyon from rim to rim to rim (about 47
miles) in one day.

Here are my vitals:
Clark Pentico
Age: 50
Weight: 192
Height 6’2″
A competitive athlete in college. Track and Cross country
Marathons: Boston, LA, Sacramento, Big Sur
Half Marthons: Big Sur Half, Great Race of Agoura, Robie Creek

Let me list off a few things I am noticing:
– Lower appetite- Lost a couple of pounds.
– When I get up in the morning, I have that “growth spurt” achiness like when I was a
teen. It is a little similar to a good workout, but not localized. A little like a flu
achiness, but much milder.
– I seem to need a little more sleep (30 to 45 minutes a day)
-Cardio seems to be progressing. I have not been in race training mode in a while but
I have a relatively flat 5k look near my house. I plan on running it about every 2 weeks
over the course of the 3 months and see where I end up.
-Mental focus seems to be improved.
I will track the 5k times and weight loss and see where we get.

Sept 11 Update:

I am having amazing results.

Faster running, better recovery, better strength, mental clarity, etc….

Since my wife is taking it I bought some more 6 jars but gave away 3 of them to close family friends that were very excited about it. They are a few weeks behind me but are already seeing results. They all bought 3 more bottles. I wish I was getting a commission.

I have been running a 5k look around my neighborhood from when we started.
I went from 24:22 to 22:06 in 42 days. Amazing!!!

We believe Sublingual NMN is the MOST IMPORTANT HEALTH DISCOVERY in decades.

But we don’t want to wait for 5-10 years for researchers to prove it. We want to elicit some proof of results from our customers to help show the world how effective it is.

We now have 3 programs ongoing:


We provide our NMN powder and sublingual tablets to 40 people, with cash prizes up to $2,000 each for those that demonstrate the most dramatic, proven results from using our product.

Our ideal is triathletes, runners, or weight-lifters who have a long history of competition that can be verified.

We are confident that taking frequent doses of NMN can help such older athletes make dramatic improvement in their performance and serve as a strong testimonial for the power of sublingual NMN.

We hear from customers that have experienced a wide range of benefits. Some that are very common, such as improvement in skin, hair and nails. Some that are more dramatic or surprising, such as:

  • Cognitive Improvement in Dementia patients
  • Relief from Prostate Inflammation
  • Reversal of recent Menopause
  • Relief from debilitating Migraine headaches
  • Improved focus in high level gran prix driver

Of course these are all anecdotes and don’t provide as strong of proof as a verifiable record of improvement in sports, but they are interesting and may be useful for others to read about.

If you have a NMN Success story, send it in to Monica@alivebynature.com, and use the subject line “Success Stories”.

If we use your success story, we will send you a 3 month supply of NMN as thanks for helping to get the word out.


We feel this will provide the strongest “proof” of efficacy, outside of clinical trials.

Competitive athletes are seeing great improvements in performance with NMN. Now we are looking for older athletes who are at the very top of their age groups.

If you or someone you know is an elite athlete and would like to make some money off your skills, let us know!
