"Bought it half-expecting nothing. First supplement in years I can actually feel — sleeping through and clear-headed by 9am."

"Replaced a shelf of eight bottles with one daily pack. Simpler, and the first stack that's made a real difference."

The Biological Shift to Expect When You Restore Your Body's Master Hormone Precursor
Testosterone isn't switched on — it's built, step by step, from raw materials your body slowly runs out of after 35. Here's what most men feel as Pregen restocks the production line.
WITHIN 24 HOURS
Sleep Starts to Settle
Magnesium glycinate and KSM-66 ashwagandha in Rebuild begin lowering the cortisol that jolts you awake — the very first night for many men.
The "Wired-Tired" Edge Softens
NMN and methylated B-vitamins in Ignite start feeding the mitochondria that make cellular energy — so the day feels less like running on fumes.
A Quieter Mind at Night
Pregnenolone is the brain's most abundant neurosteroid. Restocking it supports the calm, "switched-off" feeling that makes deep sleep possible.
Marcus T. (24 years old)
"First night I actually slept until my alarm. I'd forgotten what that felt like. Didn't expect anything that fast."
1 WEEK
The Cortisol Drain Slows
A week of consistent ashwagandha means less of your master precursor gets "stolen" to make stress hormones — and more is left to make testosterone.
Energy Gets a Floor Under It
As NAD+ levels rebuild, the 3pm crash flattens out. Not a caffeine spike — a steadier baseline.
Deeper, Less-Interrupted Sleep
Fewer 2–4am wake-ups for most men, because the hormonal cause — not just the symptom — is being addressed.
Jake M. (27 years old)
"By day five the afternoon slump was barely there. I kept waiting for the 'placebo' to wear off. It didn't."
1 MONTH
Free Testosterone Has Room to Rise
Boron has been lowering SHBG for ~30 days — freeing testosterone that was already in your body but bound and unusable.
Training Starts Paying You Back
With the hormonal environment improving and Omega-3 reducing recovery-killing inflammation, the same effort in the gym starts showing up again.
You Feel Like Yourself Again
Steadier mood, sharper recall, more drive. The things that quietly faded after 40 start coming back — and people around you notice.
Brandon K. (23 years old)
"A month in, my wife asked what I'd changed. More patient, more energy, back in the gym. I'd spent years thinking this was just 'getting older.' It wasn't."
Powerful Ingredients That Bring Results
Rooted in biology. Calibrated for men over 40. Backed by peer-reviewed research — at clinical doses, in their most absorbable forms.
Why Longevity Doctors Keep Coming Back to One Molecule
01
The Inevitability Myth
You've been told declining testosterone is just aging. "Live with it — or inject synthetic hormones for life."
Both miss what's actually happening.
Your body hasn't forgotten how to make testosterone. The factory is still standing. It's simply run low on the raw materials and cofactors that let it run.
"Live with it — or inject synthetic hormones for life.”
02
The Pregnenolone Steal
Here's the part almost no one explains.
Your master precursor — pregnenolone — sits at the top of the hormone cascade. Cholesterol → Pregnenolone → DHEA → Testosterone.
But chronic stress hijacks that same molecule to manufacture cortisol instead. It's called pregnenolone steal. The more stress you carry after 40, the less of your master precursor is left to make testosterone.
03
The Result
After 35, six things break down at once:
Pregnenolone production drops — up to 60% by age 75
The testosterone-producing cells in the testes decline in number and responsiveness
Cortisol steals the precursor before testosterone can be made
Your gut extracts less zinc, magnesium and B-vitamins from the same food
Body fat converts more testosterone into estrogen
SHBG binds up the testosterone you do make, leaving less free and usable
Fix only one — and the other five still drag you down.
04
Why Single-Ingredient Boosters Fail
Most "test boosters" pick one mechanism and call it a formula. Buying raw pregnenolone off Amazon for $20 is like dropping bricks at a factory with no workers and no power. Nothing gets built.
After 40, it's never one broken thing. It's six. And the only fix that works is the one that addresses all six at once.

"Results in months," if at all
Expert Approved,
Formulated by Doctors
"Most testosterone products chase the end result with one or two ingredients. We formulated Pregen the other way around — starting upstream, supporting the full pathway the body uses to make testosterone itself, at clinically-referenced doses and in the forms it can actually absorb. Every ingredient in Ignite and Rebuild earns its place. Nothing is in there for the label."

We know the upstream system works, because we've seen the change in thousands of men over 40. But we also know nothing works for everyone.
If you're in the small percentage it doesn't move, you shouldn't pay a cent.
The only way to lose is to keep waking up at 3am, doing nothing.
Top 10 Questions About Pregen
How long until I see results?
Most men notice sleep shifting within the first week, steadier energy by day 30, and the full system online by day 90 — when it becomes your new baseline, not a temporary boost.
Who is Pregen for?
Men, generally 40+, who feel the change — worse sleep, lower energy, less drive, slower recall — and want to address the root cause instead of masking symptoms. Intelligent men who'll read a label.
Is this the same as testosterone (TRT)?
No. TRT replaces your hormones from the outside, often for life. Pregen supports your body's own production by restocking the raw materials it's run low on. You stay in the driver's seat.
Are there side effects?
Pregen uses clinically-referenced doses in well-tolerated, highly-absorbable forms (glycinates, triglyceride Omega-3, methylated B's). As with any supplement, check with your doctor if you take medication or have a condition.
How do I take it?
Two parts: Ignite in the morning (your daily hormone activation pack) and Rebuild at night (recovery, cortisol control, deep sleep). AM and PM, the way your body actually uses each ingredient.
Why is it more expensive than a $30 booster?
Because the forms cost more. KSM-66, pharmaceutical-grade NMN, triglyceride Omega-3, methylfolate. Build this stack yourself at the same quality and you'd spend $350+ across 14 bottles — with the wrong timing and no absorption enhancer.
Will it help me sleep?
For many men, it's the first thing they feel. The 2–4am wake-up is often a hormonal and cortisol issue — exactly what Rebuild is built to address.
Do I need to cycle it?
No. Pregen supports an ongoing biological process. It's designed as a daily system, not a cycle.
What if it doesn't work for me?
Then you don't pay. Full 60-day money-back guarantee — keep the bottles.
Is it tested and made to standard?
Made in the USA, cGMP-certified facility, third-party tested, full label transparency. No proprietary blends — you see every dose.
