Peptides for Men Over 40: The Truth About Fat Loss, Muscle, Recovery & the Gray Market with Jay Campbell

Are peptides the next frontier of men's health optimization, or has the industry become a dangerous free-for-all?

If you're a man in your 40s, 50s, 60s, or beyond, you've probably heard about peptides like tirzepatide, retatrutide, BPC-157, TB-500, MOTS-c, and SS-31. But do you really know what they do, which ones have meaningful human research behind them, and what risks you need to understand?

In this episode of the Over 40 Alpha Podcast, Funk Roberts sits down with Jay Campbell, a longtime health optimization advocate, bestselling author, and co-founder of BioLongevity Labs, for a wide-ranging conversation about the rapidly growing peptide industry.

Jay shares how his personal testosterone journey led him into hormone optimization more than 25 years ago and why he's increasingly concerned about questionable suppliers, counterfeit products, and the growing number of inexperienced people selling experimental compounds.

Funk and Jay also dive into GLP-1 medications, the difference between losing weight and improving body composition, and why resistance training, protein, sleep, and appropriate medical care remain essential for men who want to become leaner and stronger.

The conversation explores emerging compounds being researched or marketed for mitochondrial function, injury recovery, muscle growth, and longevity, including where the evidence is still limited.

What You'll Learn

• Why Jay believes the peptide market is becoming increasingly risky.
• The difference between approved GLP-1 treatments and experimental research peptides.
• Why weight loss without muscle preservation can create new problems.
• Jay's perspective on GLP-1 microdosing and conventional dosing.
• What men should understand about testosterone and metabolic health.
• Why MOTS-c and SS-31 attract attention in mitochondrial research.
• What is known — and not yet established — about BPC-157 and TB-500.
• Why Jay is interested in emerging muscle-growth and longevity compounds.
• The importance of product quality, clinical evidence, and medical oversight.
• Why no peptide replaces training, nutrition, sleep, and consistent habits.
