Hormonal

Oral testosterone supplementation (80 mg twice daily) increases lean body mass and decreases fat mass in healthy elderly men (aged 60+) with low-normal gonadal status over a 12-month period.

For older men with low-normal testosterone levels, oral testosterone therapy can effectively increase muscle mass and reduce body fat over a year. However, it does not necessarily improve muscle strength, and monitoring for side effects like increased hematocrit is crucial. This suggests that addressing hormonal deficits can be a viable strategy for managing body composition in aging, even without overt hypogonadism.

GoodSupportsHIGH confidence
This study has demonstrated that a standard dose of oral testosterone undecanoate administered for 12 months to older men without overt hypogonadism increases muscle mass and decreases fat mass.

Why this rating

Randomized, double-blind, placebo-controlled trial with a relatively large sample size (n=76) and long duration (12 months), though limited to a specific demographic.
