THE
FUNCTIONAL AF
TESTOSTERONE
RESET More drive. More strength. Less of whatever the hell is happening right now.

Your testosterone has been declining since your mid-twenties. By forty, most men have lost 15-20% of their peak levels — and they're doing at least three things every day that make it worse.

This is the protocol that fixes it. Without injections. Without a prescription. Without becoming the guy who talks about his hormones at dinner.

YOU'RE NOT GETTING OLDER.
YOU'RE RUNNING LOW.

⚡ Dead by 2pm

Not tired from doing too much. Tired from doing nothing. Testosterone plays a direct role in how your cells produce energy. When it drops, so does everything else.

💪 Getting weaker

Same training. Less result. Testosterone is the primary anabolic hormone. Without it, your body struggles to build or even maintain muscle tissue. This isn't about effort.

🔥 Belly fat that won't leave

Low testosterone increases fat storage. That fat converts testosterone to estrogen. More belly fat = more estrogen = less testosterone. It feeds itself. Congratulations.

🧠 The 15-minute email

Testosterone receptors exist throughout the brain. Low levels are directly linked to reduced cognitive function. The mental sharpness you had at 35 didn't just evaporate.

😐 Flatness where drive used to be

Testosterone drives the will to compete, pursue, and give a damn. When it drops, men describe a kind of flatness. Things that used to matter stop mattering. This isn't depression.

😴 Sleep that doesn't fix anything

Low testosterone disrupts deep sleep. Poor sleep further suppresses testosterone. Another feedback loop. Another thing getting worse by itself while you blame getting older.

None of this is inevitable. It's fixable.
And the fix doesn't require a prescription.

What this actually is

NOT A SUPPLEMENT AD.
AN ACTUAL SYSTEM.

Most "testosterone boosters" are marketing dressed up as science. A proprietary blend of things that sound good on a label and do approximately nothing to your blood levels.

This is a lifestyle protocol — built around the six variables that have the most direct impact on testosterone production: sleep, stress, nutrition, training, supplementation, and what you need to stop doing immediately.

"Your testosterone isn't low because you're old. It's low because you've been doing a predictable set of things that suppress it. Change the inputs. Change the output."

I've been having this conversation with men over forty for fifteen years. Once they fix the actual inputs — especially sleep — the results are fast, measurable, and consistently surprising to men who had accepted that this was just what forty feels like.

What's inside

EVERYTHING YOU NEED.
NOTHING YOU DON'T.

01
The Problem
What's Actually Happening to You

The six symptoms nobody connects to testosterone, and why the feedback loops that create them get worse the longer you ignore them.

02
The Killers
The 5 Testosterone Killers

Chronic sleep deprivation, cortisol, inflammatory diet, overtraining, and endocrine disruptors. Most men are doing all five. Here's how to stop.

03
The #1 Lever
The Complete Sleep Protocol

Testosterone is produced during deep sleep. One week of poor sleep reduces levels by 15%. The full protocol: temperature, darkness, timing, and what to stop doing before bed.

04
The Training
How to Train For Testosterone

Compound lifts, session length, sprint protocols, and rest days. Most men over 40 are either doing too little or too much. Both suppress testosterone.

05
The Stack
6 Supplements With Real Evidence

Vitamin D3/K2, zinc, ashwagandha KSM-66, magnesium glycinate, creatine, and boron. What each one does, why it works, and exactly how to dose it.

06
The Plan
The 8-Week Stacked Protocol

Week-by-week instructions so you're not changing everything at once. Each change compounds on the last. Most men notice a difference within two weeks.

THE GUYS WHO DO THIS AND TRACK IT ARE ALWAYS SURPRISED BY HOW MUCH CHANGES.

I'm not a wellness influencer with a ring light and a supplement deal. I'm a trainer who's spent 15 years in actual gyms with actual men over 40 — watching them suppress their own testosterone without realizing it, and watching them turn it around once they understood what was happening.

I also spent years as a cast member at CollegeHumor and worked on Hollywood productions. Which means I've had to stay in shape under conditions that are not exactly optimal for testosterone.

This protocol is what I've actually used. With real clients. On myself. It works.

WHAT MEN OVER 40
ACTUALLY SAY.

★★★★★

"The sleep protocol alone changed everything. I thought I was sleeping fine. I wasn't. Two weeks in and I felt like a different person. The rest of the protocol on top of that was just bonus."

— Chris M., 46 · Atlanta

★★★★★

"Got tested before and after. 12 weeks, numbers went from 380 to 540 total testosterone with nothing but this protocol. No injections. No prescription. Just fixing what I was doing wrong."

— Ryan T., 51 · New York

★★★★★

"The part about overtraining hit me hard. I was in the gym 6 days a week wondering why I was getting weaker. Cut to 4 days, added the recovery protocol, and in 6 weeks my strength went back up."

— Marcus D., 44 · Los Angeles

QUESTIONS YOU'RE
ALREADY THINKING.

Do I need to get blood work done first? +
You don't need to — the protocol works regardless. But I recommend getting tested before you start and again at 12 weeks so you have actual numbers. It's more motivating than guessing, and seeing the change is satisfying. Direct-to-consumer labs like Marek Health make this easy without a doctor's visit.
Is this the same as TRT? +
No. TRT (Testosterone Replacement Therapy) is a medical treatment involving exogenous testosterone — prescribed by a doctor. This is a lifestyle protocol that optimizes your body's natural production. Some men will still need TRT after doing everything right. But most men haven't done everything right yet, and the difference is significant.
How long until I notice a difference? +
Most men notice a difference in energy and sleep quality within 2 weeks just from fixing their sleep environment. The full protocol compounds over 8 weeks. Measurable changes in body composition and strength typically show up around the 6-8 week mark.
I already take some of these supplements. Is this still useful? +
Almost certainly yes — because supplements are the last piece, not the first. Most men taking testosterone supplements are sleeping poorly, training incorrectly, and eating in ways that suppress testosterone. The supplements work significantly better when the other variables are addressed first.
Does this work if I'm over 50? +
Yes. The inputs that suppress testosterone don't stop mattering after 50. The protocol addresses the root causes regardless of age. The degree of change varies — men who have been suppressing their testosterone for longer tend to see larger improvements when they stop.
Is this a physical book or digital? +
Digital PDF delivered instantly via Kit. Read it on any device or print it. Either works.

STOP ACCEPTING
HOW YOU FEEL.

Most men your age have accepted that this is just what forty feels like. The fatigue. The weight. The flatness. It isn't. You were doing the wrong things. Now you know the right ones.
