In this episode of the Longevity & Lifestyle Podcast, Claudia von Boeselager sits down with Dr. Alexander Grinberg, one of the few physicians who has worked with peptide therapeutics since the 1980s.
Long before peptides became a social media trend, Dr. Grinberg was involved in clinical research using peptide bioregulators in patients with autoimmune disease, immune dysfunction, radiation exposure, viral illnesses, and regenerative medicine. Drawing on more than 35 years of clinical and scientific experience, he explains what peptides can realistically do, where the evidence is strongest, and why personalized medicine matters far more than following influencer protocols.
They discuss the biggest mistakes people make when self-experimenting with peptides, why proper diagnostics are essential before starting treatment, cancer considerations, mitochondrial health, immune function, bioregulators, GLP-1 medications, and what the future of peptide medicine may look like.
Whether you're curious about BPC-157, GHK-Cu, Epitalon, MOTS-c, SS-31, or simply want to separate scientific evidence from marketing hype, this conversation offers one of the most balanced and informative discussions on peptides available today.
In this episode you'll learn:
- Why peptides are far more powerful than most people realize
- The biggest risks of self-prescribing peptide protocols
- Who should avoid certain peptides altogether
- The blood tests and biomarkers to check before starting
- Why longevity treatments should always be personalized
- The fascinating history of peptide medicine dating back to the 1980s
- How peptides may support healthy aging, immune health and regenerative medicine
- The future of peptide therapeutics and precision longevity medicine
