Hormone Health and Peptides: Jay Campbell on Living Leaner, Longer, and Stronger

A kick to the groin during a semi-pro basketball game changed the trajectory of Jay Campbell's entire life. He was 29, working as an advertising rep at the Los Angeles Times, about a month from turning 30. Weeks after the injury, he started feeling completely run down with no explanation. His doctor referred him to a Harvard trained endocrinologist named Dr. Raymond Scruggs, who ran labs and discovered Jay had the testosterone levels of an 85-year-old man. The year was 1999. Testosterone therapy was barely on the radar. There were almost no books about it. But Dr. Scruggs put Jay on a course of therapeutic testosterone, and within six weeks, everything shifted. Jay never looked back.

A kick to the groin during a semi-pro basketball game changed the trajectory of Jay Campbell's entire life. He was 29, working as an advertising rep at the Los Angeles Times, about a month from turning 30. Weeks after the injury, he started feeling completely run down with no explanation. His doctor referred him to a Harvard trained endocrinologist named Dr. Raymond Scruggs, who ran labs and discovered Jay had the testosterone levels of an 85-year-old man. The year was 1999. Testosterone therapy was barely on the radar. There were almost no books about it. But Dr. Scruggs put Jay on a course of therapeutic testosterone, and within six weeks, everything shifted. Jay never looked back.

In this episode of Fountain of Vitality, host LaMont Leavitt sits down with Jay Campbell, co-founder of BioLongevity Labs, bestselling author, and one of the most experienced voices in the therapeutic hormone and peptide space. Jay shares what he has learned across 25 years of self experimentation, working with thousands of patients, and writing eight books on how to optimize the human body from the inside out.

 The Endocrine System Runs Everything 

Jay does not mince words about where health optimization starts. The endocrine system is the most important regulating system in the human body, and if it is off, everything else follows. He points to a staggering number: 85% of adults in the United States are currently walking around with some level of hormone deficiency. Among men and women over 40, 74% are classified as obese by BMI standards, and obesity and hormone deficiency are inseparable. You cannot have one without the other.

The reasons are layered. People are not moving like they used to. Everything from groceries to household supplies arrives at the door. Combine that with a food supply loaded with nitrates, GMOs, and processed ingredients, and the result is a population that is inflamed, fatigued, and hormonally-suppressed.

 Why Your Doctor Cannot Help You Here 

Jay makes a distinction between sick care and health optimization that runs through the entire conversation. The traditional medical system is built to manage disease, not to optimize performance. If you walk into your family doctor's office and say you want to live to 125, they will look at you like you have lost your mind. They are trained to check symptoms and prescribe medications, not to help you reach your peak physical state.

He also challenges the routine diagnostic testing model. Colonoscopies, mammograms, and prostate screens are designed to find something wrong. And once a doctor finds a growth or an irregularity, the default recommendation is removal, even when there are no symptoms. Jay argues that for older adults, invasive procedures carry serious risk, and the diagnosis itself can become a self-fulfilling prophecy when fear takes over.

 Hormones First, Peptides Second 

Jay is firm on sequencing. You cannot layer peptides on top of a broken hormonal foundation. That is like pouring water into the gas tank of a Ferrari. The body runs on the efficiency of its hormonal circuitry, and until that system is functioning properly, nothing else will work the way it should.

Once hormones are dialed in, the door opens to peptides, GLP1 compounds, and small molecules that can accelerate fat loss, recovery, and cellular repair. Jay has been using peptides since 2003, long before most physicians even knew the term existed. His latest book, Metabolic Awakening with GLP Peptides, is over 700 pages with 1,300 scientific references and represents the most comprehensive guide available on the subject.

 Track Your Energy Like a Business 

One of the most practical takeaways from the conversation is Jay's approach to personal tracking. A mentor told him in his 20s to write down how he felt every single day: energy levels, nutrition, workouts, accomplishments, and overall state of being. Jay did not start until his early 40s, and he says he regrets the two decades of data he missed.

By tracking consistently, he discovered his own seasonal energy patterns. March through May are his highest output months. June and July are rest periods. He now plans his entire calendar around those rhythms, scheduling travel, speaking engagements, and business expansion during peak months and blocking off recovery time when his energy naturally dips.

 Self Love Is the Starting Line 

Jay and LaMont spend a significant portion of the conversation on the inner work that supports physical health. Jay is direct about it: if you do not love and trust yourself, nothing else will land. He talks about standing in front of a mirror and affirming that self trust out loud, every day. He credits his wife and a spiritual coach for helping him understand that the parts of ourselves we dislike are not our authentic selves but fragments of inherited beliefs, childhood experiences, and unprocessed emotions.

He connects this back to health by pointing out that people who are physically suffering cannot access the clarity or energy needed for spiritual growth, purpose, or service to others. Fix the body first. Then go deeper.

Key Takeaways

  • Hormones must be optimized before adding peptides or GLP1 compounds

  • The traditional medical system is designed to manage disease, not optimize health

  • Routine diagnostic procedures carry risk and can trigger fear based decision making

  • Tracking your daily energy, nutrition, and output reveals patterns you would otherwise miss

  • Seasonal energy rhythms can be used to plan business and personal calendars
