As the population ages, the prevalence of age-related hypogonadism is increasing, leading to a rise in demand for testosterone replacement therapy (TRT). This is evident from the significant increase in revenue from TRT prescriptions, reaching billions of dollars annually. Dietary supplements, including testosterone supplements, have also gained popularity, especially with the accessibility of online marketplaces like Amazon. The study focuses on the top 50 dietary testosterone supplements sold on Amazon Marketplace, aiming to evaluate their characteristics, claims, cost, and customer satisfaction. Researchers documented active ingredients, 30-day costs, 5-star ratings, and claims of these products, analyzing common ingredients present in at least 50% of the supplements.




Summary

T supplements sold on Amazon Marketplace vary widely in composition, and their 30-day cost can be substantial. However, there is limited evidence supporting their effectiveness and safety. Further research and trials are required to identify the essential ingredients in these supplements.
