Key Takeaways: TSH alone misses early thyroid dysfunction in a significant percentage of patients. Dr. Duben explains which additional markers — Free T3, Free T4, Reverse T3, and thyroid antibodies — are essential for a complete picture, why “normal” lab results don’t always mean optimal function, and what a root-cause thyroid workup actually looks like in clinical practice.

Key Takeaways: The 2026 HHS reclassification removed 14 peptides from compounding pharmacy availability overnight. Dr. Duben breaks down each peptide, what it was used for clinically, why the reclassification happened, and what options remain for patients who were benefiting from peptide therapy.

Low Libido, Low Testosterone & Testosterone Optimization
Dr. Michael Duben explains why most testosterone clinics miss the root cause — and what a true endocrinologist-led approach to men's hormonal health and hormone optimization looks like.Key Takeaways: Most testosterone clinics treat the number, not the patient.

Dr. Duben explains how TSH receptor antibodies drive the condition, why standard treatment options like Methimazole, radioactive iodine, and surgery each carry different long-term implications, and what functional medicine approaches — including selenium, gut health, and stress modulation — can do to address the immune root cause.
