How we write these articles
Every article starts from a real question and works toward a straight answer, then explains the reasoning. We lean on primary sources such as FDA labels and announcements, National Institutes of Health resources, MedlinePlus and guidelines from groups like The Menopause Society, the Endocrine Society and the American Urological Association.
Where evidence is strong, we say so. Where it's early, limited to animal studies or simply missing, we say that too. You won't find promises of results here, and you'll see clear notes about FDA status, including when a medication is compounded and therefore not FDA-approved.
What you'll find
- Menopause and hormone therapy: who can and can't use it, routes, blood clots, migraines, blood pressure, progesterone and stopping.
- Testosterone and men's health: diagnosis, who shouldn't take it, fertility, sleep apnea, enclomiphene and erectile changes.
- Peptides: what they are, how they're regulated, the July 2026 FDA advisory votes and where evidence stands for specific peptides.
- NAD+ and longevity: safety, interactions, precursors and realistic expectations.
- Sexual wellness: PT-141, oxytocin, low desire and what to check first.
- Labs and biomarkers: what common tests mean and why 'normal' doesn't always mean optimal.
- Former athletes and busy professionals: metabolism after sport, sleep apnea and health risks that tend to be missed.
A note on peptides and compounded medications
Many products discussed here, including most peptides, NAD+ injections and some hormone preparations, are compounded by licensed pharmacies. FDA states that compounded drugs are not FDA-approved and that it doesn't verify their safety, effectiveness or quality before they're marketed.
In July 2026, FDA's Pharmacy Compounding Advisory Committee voted on several peptides, recommending some for the list of substances pharmacies may compound and voting against others. Those votes are advisory and not binding, and inclusion on that list would not be FDA approval. We update relevant articles as FDA acts.
Where to start
If you're weighing a specific treatment, the 'who shouldn't take it' articles are a good first stop, because they cover the safety questions a clinician will ask anyway. If you're trying to make sense of symptoms, the articles on sleep apnea, fatigue and normal-but-not-right lab results help you sort out what to check before reaching for a medication.
If you've been told something conflicting, such as that migraines rule out hormone therapy or that testosterone causes prostate cancer, look for the articles on those topics. Many long-held assumptions have shifted as better evidence arrived, and we explain where guidance stands today.
