Health optimization for men, with the evidence attached
It all starts
with the base.
Sleep, training, hormones, body composition, labs: get the base right before you optimize on top of it. 80 guides to peptides, supplements and lifestyle, graded on one evidence ladder, and a forum organized by the question you came with. Every post says whether it is anecdote or cited research.

The base
Get the fundamentals right first.
Sleep, training, protein, how you eat. The lifestyle guides are where optimization starts, and they are graded on the same evidence ladder as everything else on the site: what the trials showed, what a cohort can and cannot say, and where the claim outruns the data.
SleepSleep durationHow long people habitually sleep, followed in cohorts of millions. Both short and long sleep track with earlier death and more heart disease, with the lowest risk around seven hours. Short sleep has a plausible mechanism; long sleep is probably a marker of illness.EstablishedSleepSleep restrictionWhat happens when healthy people are made to sleep less, in the lab. Two weeks at six hours a night degrades attention as much as two nights with no sleep, and the people affected do not feel it. An extra hour improved short sleepers' sleep but, in one trial, not metabolism.EstablishedTrainingResistance trainingLifting against resistance, followed in cohorts of hundreds of thousands. Any amount is associated with 15 to 20% lower mortality, the lowest risk sits around an hour a week, and the benefit adds to aerobic exercise. Above a couple of hours a week the curve flattens or turns.EstablishedTrainingAerobic exerciseMovement that raises the heart rate, measured in 30 million people by questionnaire and tens of thousands by accelerometer. Going from nothing to the recommended 150 minutes a week is associated with about a third lower mortality. Above that the gains shrink.EstablishedNutritionProtein intakeHow much protein to eat, as opposed to which powder. More protein adds small muscle and strength gains with resistance training, with a threshold near 1.6 g per kg a day in younger adults. Cohorts link animal protein to slightly higher mortality, plant protein to lower.EstablishedNutritionIntermittent fastingEating within a window or fasting on set days. It produces weight loss, and in head-to-head trials about the same as simply eating less. Alternate-day fasting edges ahead by about a kilogram in a 2025 network meta-analysis. The metabolic benefits beyond weight are small.Established

How discussion is organized
Ten sections. One standard.
Rooms named for the question you arrive with, from testosterone to sleep to labs, with the guides that answer it listed in each. Every post carries an evidence label, so an experience log and a trial read-out never look the same.
Testosterone & Hormones
Testosterone, TRT, estradiol, SHBG, thyroid and the growth hormone axis, against the labs and the trials.elevated safety rules
8Body Composition
Fat loss, muscle gain, GLP-1 drugs, protein and fasting, and what the trials actually measured.
13Training & Performance
Strength, conditioning, programming, injury recovery, and the ergogenics with evidence.
5Sleep & Recovery
Sleep duration and quality, stress, cold and heat, and what actually restores you.
1Sexual Health
Erectile function, libido, fertility, and the compounds and habits with trial evidence.
4Mental Performance & Mood
Focus, memory, motivation, stress, anxiety and mood, and what has been tested in people.
2Longevity & Healthspan
Aging biology, cardiovascular and metabolic risk, and the interventions with human data.
10Labs & Bloodwork
Reading your own labs, reference ranges, what to test and how often, and what a number can and cannot say.
2Peptides & Compounds
The research peptides: mechanism, evidence, safety, stability, and sourcing talk within the rules.elevated safety rules
5Supplements
Vitamins, minerals, amino acids and extracts: what the trials found, and what the label is allowed to say.

Study summaries
Plain language, always linked to the source.
Written by members, reviewed before featuring, and deliberately boring about what the evidence does and does not show.
Meta-analysis2024
GLP-1 receptor distribution in the human CNS: what the mapping studies actually resolved
A review of autoradiography and single-cell transcriptomic work mapping GLP-1 receptor expression in human brain tissue. The receptor is far more restricted in the human CNS than r…
Takeaway
Rodent CNS receptor maps do not transfer cleanly to humans, which weakens a common bridge between animal behavioral results and human claims.
Preclinical2024
An evidence map of BPC-157 preclinical studies, 1993 to 2024
A systematic scoping review counting roughly 180 published animal studies, of which the overwhelming majority originate from a small number of affiliated research groups. Effect si…
Takeaway
The preclinical literature is large but narrow. Consistency within one research network is not the same thing as replication.
Early clinical2023
Degradation kinetics of lyophilised peptides under realistic storage conditions
Bench work measuring degradation of several model peptides across temperature and humidity conditions chosen to resemble domestic rather than laboratory storage. Deamidation and ox…
Takeaway
Storage conditions can change what is actually in a vial more than most discussions assume. Reported results without storage details are hard to interpret.
How moderation works here
Candid, but not lawless.
A community about a contested subject only stays useful if disagreement is safe and enforcement is legible. So the rules are narrow, written down, and applied in the open.
- 01
No shadow banning. Ever.
There is no hidden state where your posts exist for you and nobody else. If your content is removed, you are told, the community sees a tombstone in its place, and the reason is written out.
- 02
Every action names the rule
Removals, warnings and suspensions all cite a numbered rule from the public rules page. If a moderator cannot name the rule, they cannot take the action. The database requires it.
- 03
Appeals go to a different person
Any action can be appealed. Appeals are decided by someone other than the moderator who acted, and the decision comes back in writing.
- 04
The whole log is public
Every public moderation action, its reason, and the outcome of any appeal sits on one page that anyone can read, including people who are not members.
What we remove, without much patience
- Sourcing, sales, and vendor solicitation
- Helping people bypass a prescription
- Dosing instructions aimed at another person
- Medical claims stated as fact without a source
- Doxxing and harassment
- Scams and undisclosed promotion
Everything else, including hard criticism of the moderators, the science, the industry, or this site, is fair game.
