Evidence-based men’s health
You came for the name. Stay for what nobody else will tell you.
One guy, no medical degree, reading the actual trials on erectile dysfunction, hair loss, testosterone, fertility and the rest — and reporting what they say, including the findings that are inconvenient for the people selling the cure.

Every clinical claim here is traced to
Who writes this
I’m Will Preston. I’m not a doctor — I’m a guy who got tired of searching these things at 1am and finding nothing but sales pages.
So I started reading the guidelines and the trials myself and writing down what they actually say. Every claim links to its source, so you can check me instead of trusting me. More about how I work — including why the byline is a pen name.
Topics
Ten things men search for at 1am
Erectile dysfunction
Physical versus psychological causes, what the prescriptions do, and what the alternatives are worth.
Weight & metabolic health
GLP-1s, body composition, and the metabolic problems that quietly drive half the other topics here.
Low semen volume
Volume and sperm count are different conditions. Nearly every product sold for one cites research about the other.
Hair loss
Two FDA-approved drugs with decades of trial data, and an industry built on top of them. What the numbers actually say.
Premature ejaculation
What works, how strong the evidence behind each option really is, and when it is worth seeing someone.
Testosterone & vitality
What low T actually is, what genuinely raises it, and why the booster aisle looks the way it does.
Penis enlargement
The honest answer, the narrow exceptions, and the methods that are actively dangerous.
Sexual health & STIs
Testing intervals, what protection does and does not cover, and how to have the conversation.
Mental health & libido
Anxiety, depression, and the sexual side effects of the drugs used to treat them.
General men’s health
Sleep, bloodwork, screening and the unglamorous baseline stuff everything else sits on.
Men’s health online is mostly two things: clinics that answer the question and then sell you the answer, and content farms rewriting each other.
Both leave out the same material — the studies that didn’t work out, the difference between the thing you’re worried about and the thing being sold to you, and the honest admission that a question isn’t settled.
That material is what this site is for. My article on fertility supplements leads with a 2,370-man NIH trial that found no benefit and one signal of harm — in a category I could otherwise earn commission promoting. That’s the standard, and it’s written down.

Do GLP-1s Cost You Muscle? What the Body Composition Data Show
A quarter to a third of the weight lost is lean tissue — proportionate to any large weight loss, not selective muscle wasting. But 5.6 kg is still 5.6 kg, and it does not come back on its own.
