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.

GLP-1s, body composition, and the metabolic problems that quietly drive half the other topics here.
In progressMental health & libido
Anxiety, depression, and the sexual side effects of the drugs used to treat them.
In progressSexual health & STIs
Testing intervals, what protection does and does not cover, and how to have the conversation.
In progressGeneral 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.
