Greenfield lab-tested five or six popular gas-station male-enhancement pills marketed with exotic superfoods and herbs. The results were the same across the board: the active ingredients are sildenafil (the compound in Viagra) and ephedra (a potent stimulant). They work, but he considers them unhealthy, especially for anyone with heart issues.

Marketed with 'superfoods' and herbs but priced at ~$3
Lab testing showed two real actives: sildenafil and ephedra
Effects feel like a strong pre-workout: clammy hands, racing heart
Risky for anyone with a heart condition

“the main two ingredients in every single one are um ephedra and sildenafil”

The No-Ejaculation Month: Mechanism May Just Be Being Pissed Off

Greenfield tried a month of no ejaculation and hated it, feeling pent-up and aggressive. He and Williamson suggest the athletic benefit some fighters claim isn't about mineral conservation or complex hormone physiology; it may simply be accumulated aggression. He debunks the idea that ejaculation meaningfully depletes zinc or minerals.

A month of no ejaculation left him angry and aggressive
Any performance edge may just be pent-up energy, not hormones
The 'wasting your minerals' claim is dismissed as bunk
You need so little mineral content that depletion is implausible

“the mechanism that it's working on might not be something quite as complex as the physiology... it could just be that you're a bit pissed…”

Fitness Is Not Health: What Endurance Racing Does to Biomarkers

Greenfield warns that training for aesthetics or performance is not synonymous with health. From testing thousands of endurance athletes, he saw thyroid and endocrine dysregulation, hypogonadism, amenorrhea, low bone density, rampant inflammation, and even pre-diabetes. If you chase an Ironman, he says, don't fool yourself that it's healthy.

Fitness and health are not the same thing
Endurance athletes show endocrine and thyroid dysregulation
Also low bone density, inflammation, and pre-diabetes
Accept the health tradeoff if you chase extreme performance

“fitness and athleticism are not necessarily synonymous with health with fertility with longevity”

How to Do Stem Cells Right: Source, Exosomes, and Guided Delivery

Greenfield lays out what separates good stem-cell treatment from hype. Ideally cells come from your own tissue, or well-screened sources like Wharton's jelly or placental tissue; they should be combined with exosomes, the signaling molecules stem cells use to communicate; and they should be delivered under ultrasound guidance so they reach the target. US regulations limit expansion, pushing some people abroad.

Use autologous or well-screened donor tissue
Combine with exosomes for better signaling
Deliver via ultrasound-guided imaging, not random injection
US bans autologous expansion; overseas clinics can expand cells

“the mechanism of the way in which they're delivered and what they're combined with is super important”

The Family Bank: Borrowing Against Whole Life Insurance

Greenfield describes a 'family bank' where every member holds a whole life insurance policy with paid-up cash. Members can borrow against themselves at rates comparable to a credit union while the money keeps compounding, and the death benefit adds protection. He frames it as a common tool wealthy families use to pass on relational and financial wealth.

Each family member holds a cash-value whole life policy
Members borrow against themselves at competitive rates
Borrowed money can stay invested while used
The death benefit adds a protection layer for the family

“we literally have hundreds and hundreds of thousands of dollars for each family member socked away that any of us can borrow against using ourselves…”

GAINSWave and the P-Shot: Shockwave Therapy for the Penis

Greenfield describes GAINSWave acoustic shockwave therapy, which supposedly breaks up old blood vessels and builds new ones, followed by a P-shot injection of platelet-rich plasma. He recounts a numbing-cream session in Miami and a lingering engorgement at dinner with his grandmother. He believes the shockwave, not the PRP, drove most of the effect, which lasted a couple of months.

Acoustic shockwave breaks up old blood vessels, builds new ones
P-shot adds centrifuged platelet-rich plasma from your own blood
Effects lasted roughly two months
An at-home device ('the Rocket') replicates a milder version

“supposedly it breaks up old blood vessels in your penis... and builds new blood vessels”

Injecting His Own Stem Cells Into His Penis

For a Men's Health assignment, Greenfield had autologous fat-derived stem cells expanded and injected into his penis in three spots. His penis was bruised black-and-blue for three days, but he says each of his three treatments gave roughly two years of strong erections and longer orgasms. He credits the stem cells over the other stacked protocols for the standout result.

Stem cells extracted from fat via 'violent liposuction,' then expanded
Bruised badly for three days after injection
Claims ~2 years of benefit per treatment, done three times
Rates it the best part of the whole 'New Year New Dick' protocol

Quarterly Relationship Retreats and Radical Honesty

Greenfield and his wife lock themselves away for two to three days at least twice a year to journal, plan the next year, and lay everything on the table, from where to live to what annoys them about each other. They began the practice using MDMA and other heart-openers to reach full transparency, but say they no longer need substances to be radically honest.

Deep planning retreats once a quarter or at least twice a year
Everything is put on the table with radical honesty
Started with MDMA and heart-openers to unlock transparency
Now they can be transparent without any substance

The Greenfield Family Playbook and Crest

Greenfield built a ~100-page family 'playbook' or constitution codifying values, a mission statement, a medieval-style crest, traditions, rites of passage, and even each member's spirit animal and brand colors. His teenage sons have their funerals planned via memento mori. He frames it as a defense against the rags-to-riches-to-rags erosion of accumulated family wisdom.

~100-page documented family values and traditions
Includes mission statement, crest, and rites of passage
Sons have end-of-life wishes planned via memento mori
Designed to counter generational loss of wisdom

Greenfield's Sauna and Cold Protocols

Greenfield details his heat and cold routine: deep sauna sweats four to five times a week for 20-45 minutes in a barrel (190-200F) or infrared sauna, avoiding steam saunas unless the water is filtered and mold-checked. For cold, he does short very-cold immersion at 33F for one to two minutes, noting cold-water immersion beats cryo chambers due to hydrostatic pressure and a wet head.

Deep sauna sweat 4-5x/week, 20-45 minutes
Barrel sauna runs hotter; infrared needs longer time
Avoid steam saunas with unknown water quality (mold risk)
Cold-water immersion beats cryo for vagus-nerve activation

“cold water immersion is better than cryotherapy chambers because of the hydrostatic pressure for the water against the skin and the fact that your head…”

Minimum Viable Water Filtration

Greenfield says a Brita isn't great and countertop RO pitchers can breed bacteria and mold. His minimum-viable pick is a countertop reverse-osmosis system like AirDoctor or AquaTru with anti-bacterial coating, or good pour-through filters like his father's brand. The gold standard is double carbon block plus RO with minerals added back.

Brita and standard countertop filters fall short
Countertop RO can grow bacteria/mold without special coating
AquaTru or similar RO units are a solid minimum
Gold standard: double carbon block + RO + remineralization

Eccentric Training Machines: ARX, X3 Bar, and Tonal

Greenfield praises eccentric and single-set-to-failure resistance training. The ARX uses a 25-horsepower motor you fight with cables for a brutally efficient workout; John Jacquish's X3 Bar delivers a bands-based budget version; and Tonal is a wall-mounted, lower-powered space-saver. He recommends the Tonal or X3 for those who can't access or afford an ARX.

ARX pits you against a 25-horsepower motor for max efficiency
X3 Bar uses heavy elastic bands for single-set-to-failure
Tonal is a wall-mounted, ~1-horsepower budget option
Eccentric training is highly time-efficient

Getting the Buzz Without Alcohol: Ketones, Apollo, and Hapbee

Greenfield offers three ways to feel relaxed or social without alcohol's toxic byproducts. KetoneAid makes ketone-ester drinks in cocktail flavors that mimic being tipsy. The Apollo is a haptic wearable simulating states like MDMA or caffeine, and the Hapbee simulates magnetic signatures of molecules like caffeine and THC. He warns ketones plus alcohol can dangerously sedate you.

KetoneAid ketone-ester drinks mimic alcohol's relaxing effect
Apollo wearable simulates states via haptics (MDMA, caffeine)
Hapbee simulates magnetic signatures like caffeine and THC
Never combine ketone esters with alcohol; sedation risk

“if you combine it with alcohol you're likely to roof yourself or whoever you serve the drink to so proceed with caution”

Prime Your Body Before Traveling for Stem Cells

Greenfield advises that international travel itself is hard on the body, and stem cells work best when inflammation is low. He recommends arriving three to four days early and doing hyperbaric sessions, anti-inflammatory support, good sleep, ginger and curcumin, and an NAD IV if available, to prime the body before treatment.

Arrive 3-4 days early to lower travel-induced inflammation
Use hyperbaric oxygen and anti-inflammatory nutrients
Take ginger and curcumin, get quality sleep
Get an NAD IV beforehand if offered

“ideally if you're going to get stem cells you want your body in as low a state of inflammation as possible”

Praying Together Before Sleep Forces You to Clear the Air

Greenfield says the last thing he and his wife do each night is pray together. He initially wasn't convinced it needed to be prayer, but realized the ritual forces reconciliation: it's hard to commune with a higher power together when something unresolved sits between you, so the nightly practice pushes them to set things right before bed.

Prayer is the final act before sleep every night
Unresolved conflict makes shared prayer feel fake
The ritual forces couples to clear the air first
Any consistent honest touchpoint could serve the same role

“it almost forces you to make sure everything's set right before you go to bed because you know the very last thing coming up is…”
