Sound familiar?

Your body has been trying to get your attention.

A few pounds each year, mostly around the middle.

Running on coffee by the 3 p.m. meeting.

Travel, client dinners and board calls that wreck every routine.

Less energy after work, and less patience at home.

A body that feels older than your plans.

You worked hard to build a good life. But when your health keeps slipping, it gets harder to enjoy the family, the freedom and the future you built it for.

Waiting has a cost, too.

Decline isn’t a straight line. It compounds. Another year of the same habits isn’t another year of the same body: it’s a little less strength, a little less energy and a longer road back. The good news runs the other way. The sooner you start, the more you get back.

Your guide

I built LongevityX after I rebuilt myself.

I’m William Bosch. I grew up in South Louisiana, and I’ve spent my whole career in health. I also learned the hard way that you can win in business and still lose your health if you don’t manage it like everything else that matters.

  1. Late 20sHigh cholesterol and severe acid reflux. I didn’t want a lifetime of medication, so I cleaned up my diet with a dietitian and built the clean protein drink I couldn’t find.
  2. The Iconic yearsThat drink became Iconic Protein. We raised millions and took it into national retail. I was building a health brand while running myself into the ground.
  3. Late 30sStartup stress caught up with me: shingles, then Bell’s palsy. Testing suggested my body was aging faster than my birthday.
  4. The rebuildI stopped guessing. I tested everything, ran one system in the right order, and got my body back.
  5. LongevityXNow I help successful adults do the same, with the testing, coaching and accountability I wish I’d had.

“I spent years putting my health last. This is the system I used to get my body back, and the one I built LongevityX around.”William Bosch, Founder

Why it hasn’t worked yet

You don’t need more willpower. You need the right guide.

Most people who come to LongevityX have already tried. The problem usually isn’t effort. It’s trying to fix a real health decline without a plan, structure or accountability.

What most people try

  • Another diet that cuts out whole food groups
  • A gym membership and good intentions
  • Apps and wearables nobody reads
  • A 10-minute doctor visit: “your labs are normal”
  • A supplement stack instead of a system
  • Starting over, every Monday

What actually moves the needle

  • Know your numbers: 100+ biomarkers
  • A plan built on those numbers and your calendar
  • Strength first, so results last
  • Food you can keep eating for years
  • A coach, and a check-in between sessions
  • Retest, so you can see it working

3 shifts that change metabolism after 40

Here’s a preview of what William teaches live. Consistency works. Restriction doesn’t.

01

Hormones shape your body more than effort does.

Why insulin and cortisol matter as much as discipline, and why the harder-you-try approach stops working after 40.

02

Muscle is what makes results last.

Why building muscle matters more than another cardio session, and why it’s the metabolism you keep.

03

Consistency works. Restriction does not.

How to stay consistent without cutting out entire food groups, travel included.

How LongevityX works

A maintenance schedule for your body

Your car gets a service schedule. Your body, the only one you’ll ever get, usually gets a check-up when something breaks. LongevityX flips that: test first, then a plan, then someone to keep you on it.

Healthcare 3.0. Reactive care waits for a diagnosis. Proactive care measures early, fixes the basics first (sleep, food, strength, stress) and keeps advanced tools for the last 20%.

1. Get your baseline

A 100+ biomarker blood panel, reviewed with a physician. Tested, not guessed.

2. Get your plan

Nutrition, strength, sleep and stress, built on your numbers and your real calendar.

3. Run it with a coach

1:1 coaching and high-touch accountability, with check-ins between sessions.

4. Retest and adjust

Watch the numbers move, then tighten the plan. No guessing, no starting over.

For those ready to go all in

The 20%: supplements

A supplement stack isn’t a system. But the right one helps.

At LongevityX, 80% of the result comes from the basics: food, strength, sleep and stress. Supplements are the last 20%, and William is picky about them. One he often recommends to clients over 40 is NMN.

NMN is the direct building block of NAD+, a molecule every cell uses to turn food into energy. NAD+ tends to decline with age. In human trials, daily NMN raised blood NAD+ levels, and in adults 40 to 65, people on NMN walked farther in a six-minute walk test than people on placebo.*

LX NMN+ gives you 1,000 mg of NMN with TMG in two capsules a day, backed by a 180-day money-back guarantee.

Picture where this goes

What are ten more good years worth?

Not just more years. Better ones. The energy, strength and confidence to enjoy the life you already built.

A father laughing with his two kids at sunset
Present for the people who matter.

Energy for the work you love.
A woman resting between strength exercises
Strong enough for the life you’re living.

  • You’ve gained weight over the years and struggled to keep it off
  • You get winded doing things that used to feel normal
  • You want to keep up with your kids, grandkids or spouse
  • You’re ready for professional guidance, not another restart
  • You invest in what matters, and your health is next

This is not for you if…

  • You want a quick fix or a magic pill
  • You want bodybuilding, contest prep or elite athletic coaching
  • You want advice, but no accountability
  • You’re shopping for the cheapest option
  • You’re not willing to change your habits

Questions

Before you register

Is the workshop really free?

Yes. It’s a free, live hour on Zoom. Bring questions; William answers them live.

Is LongevityX for athletes?

No. LongevityX isn’t elite performance coaching, bodybuilding or contest prep. It’s for adults 40–70 who want to lose weight, rebuild strength, improve stamina and take back control of their health.

What if I’ve tried everything before?

Most clients have. The problem usually isn’t effort; it’s the lack of the right plan, structure and accountability. LongevityX helps you stop guessing and follow a system built around your life.

Do I need to be in shape to start?

No. Many clients start because they feel heavier, weaker or less capable than they want to be. The plan meets you where you are.

What does LX360 cost?

LX360 is a year-long, high-touch program, and the investment depends on the level of support you need. It’s shared on your Health Reset Call, along with the other ways to start if a full year isn’t the right fit yet.

Is this medical care?

No. LongevityX provides health coaching, education and accountability. Blood testing may involve lab partners and physician review. LongevityX doesn’t replace your physician or emergency care.

Where does NMN fit in?

Supplements are the last 20%, after food, strength, sleep and stress. NMN is one William often recommends to clients over 40, which is why LongevityX offers LX NMN+. It supports the basics; it doesn’t replace them.

Ready to stop fighting this alone?
