Read this before acting on anything published on this site.
Over 40 Protocol publishes general information about men's health, fitness, and wellness. It is educational content, not medical advice, diagnosis, or treatment, and it is not a substitute for the judgement of a qualified healthcare professional who knows your history. Reading this site does not create a doctor-patient relationship.
Always consult a licensed physician before starting any supplement, device, training programme, or change to your diet — particularly if you have a medical condition, are taking prescription medication, or are being treated for heart, blood pressure, liver, kidney, or hormonal conditions.
Nothing here should be used to delay, replace, or discontinue treatment your doctor has prescribed. If you think you may have a medical emergency, call your doctor or your local emergency number immediately.
Dietary supplements discussed on this site have not been evaluated by the Food and Drug Administration, and are not intended to diagnose, treat, cure, or prevent any disease. Supplements can interact with prescription medication. Products marketed for sexual performance in particular have a documented history of containing undisclosed pharmaceutical ingredients, so buy only from the manufacturer or an authorised seller, and tell your doctor what you are taking.
Any outcomes described on this site are illustrative, not typical, and not promised. Age, genetics, baseline health, medication, consistency, and many other factors determine what any individual experiences. No result is guaranteed.
We earn commissions on some products discussed here. See our affiliate disclosure. A commercial relationship never changes the safety guidance on this page: check with your doctor first.
