In this episode of Bathroom Diaries, I sit down again with Dr. Rob Frankel to talk about something most people have never heard of — somatopause. We talk a lot about menopause and andropause. But there is another hormonal shift that affects both men and women starting as early as their 30s: the gradual decline in growth hormone.
This conversation is Part 4 of my Peptide Playbook series, where we explore how growth hormone signaling changes over time, why IGF-1 testing matters, and how peptides like tesamorelin, CJC-ipamorelin, and sermorelin may support the body's own natural growth hormone production.
In this episode, we discuss:
✨ What somatopause actually is
✨ Why IGF-1 is the most useful marker to evaluate growth hormone decline
✨ How muscle loss, fat gain, fatigue, poor sleep, and brain fog may be connected
✨ The role of growth hormone analog peptides
✨ Why sleep quality and sugar intake affect nighttime hormone release
✨ How GLP-1 therapies support metabolic health and hormone balance
✨ The connection between fatty liver, insulin resistance, and longevity
✨ Who is (and is not) a candidate for peptide-based support
✨ The real clinical studies behind these therapies My goal with this series is simple: to demystify longevity medicine and bring medically responsible conversations about peptides into the open — so patients can make informed decisions with qualified physicians.
Somatopause is rarely discussed, but understanding it can change how we think about aging, metabolism, cognition, and strength across the lifespan. If you're interested in hormone optimization, peptide therapy, or proactive aging strategies, this episode is for you.
