The Executive’s Guide to Testosterone Optimization After 40 — What Actually Works
Testosterone begins declining at roughly 1–2% per year after age 30. By 50, many men are operating at 30–40% below their peak testosterone levels. The symptoms — low energy, reduced muscle mass, increased body fat, poor sleep, diminished drive and focus — are not personal failures. They are biological facts. The question is whether you address them or accept them.
For executives and entrepreneurs — men whose performance output has direct financial and leadership consequences — testosterone optimization is not a vanity project. Low testosterone reduces cognitive function, emotional regulation, stress tolerance, and physical presence. It literally makes you a worse CEO.
Rhett Kenagy built his testosterone optimization protocol alongside the 7-month transformation. Here is the evidence-based framework that actually moves the needle — before considering medical intervention.

When to Consult a Physician
If natural optimization protocols produce no measurable improvement after 90 days of full adherence, a hormone panel (testosterone, free testosterone, SHBG, LH, FSH, estradiol) is the appropriate next step. Always consult a qualified physician before considering any hormonal intervention. Rhett is not a physician — the above represents his personal protocol and should not be taken as medical advice.
