Mind & Matter
Whether food, drugs or ideas, what you consume influences who you become. Learn directly from the best scientists & thinkers alive today about how your mind-body reacts to what you feed it.
The weekly M&M podcast features conversations with the most interesting scientists, thinkers, and technology entrepreneurs alive today.
Not medical advice.
At M&M, we are interested in trying to figure out how things work, not affirming our existing beliefs. We prefer consulting primary rather than secondary sources and independent rather than institutional voices. If we encounter uncomfortable truths or the evidence suggests unfashionable ideas may be valid, so be it.
As the host, my aim is to help you better understand how the body & mind work by curating & synthesizing information in a way that yields science-based insights that you can choose to use or disregard in your own life. Taking ownership of your health starts with taking ownership of your information diet.
I am motivated to connect the dots and distill general principles from what I learn, preferring to ask questions and play devil’s advocate to debating or incessantly pushing my own viewpoint.
My beliefs:
- Taking ownership of your health starts with taking ownership of your information diet.
- All knowledge is provisional and we must work hard to prevent ourselves from becoming attached to our favorite ideas & preferred conclusions.
- Wisdom comes from an iterative, trial-and-error process of learning and unlearning. Letting go of pre-conceived notions can be painful, but pain is information.
Sometimes modern discoveries teach us we must unlearn received wisdom. Other times, modern information overload & historical chauvinism cause us to forget ancient wisdom which stills applies. The framework for learning that I embody is inspired by three Ancient Greek maxims inscribed in the Temple of Apollo at Delphi:
- “Γνῶθι σεαυτόν” (Know thyself)
- “Μηδὲν ἄγαν” (Nothing in excess)
- “Ἐγγύα πάρα δ Ἄτα” (Certainty brings insanity)

Peptides for Tissue Repair: BPC-157, TB-500 & the "Wolverine Stack" | Episode 285
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
The science, hype, and unknowns surrounding popular peptides like BPC-157 & TB-500 ("Wolverine stack") for injury recovery & tissue repair.
Nick & Dr. Flynn McGuire discuss the surge in peptide use for injury recovery. They cover peptide basics, the preclinical evidence for BPC-157 and TB-500, mechanisms like angiogenesis and tissue repair, the lack of robust human trials, sourcing risks, regulatory bans, and the gap between anecdotal reports and scientific certainty.
TOPICS DISCUSSED:
- Peptide basics: Short amino acid chains (e.g., insulin, GLP-1 agonists); BPC-157 derived from gastric juice, TB-500 a fragment of thymosin beta-4.
- Rise in popularity: Driven by podcasts, social media, biohacking culture, and post-COVID distrust in institutions; “bro science” often precedes formal research.
- BPC-157 mechanisms: Pleiotropic effects including VEGF upregulation, nitric oxide pathways, angiogenesis, reduced fibrosis, and possible neuromuscular stabilization.
- TB-500 & “stacking”: Often combined with BPC-157 for presumed synergy; marketed as “Wolverine stack” for rapid healing.
- Evidence limitations: Strong rodent data for tendon/muscle repair, but almost no high-quality human trials; one small retrospective study and ongoing phase 2 trial in China.
- Safety and risks: Unknown long-term effects, potential cancer concerns via angiogenesis; no established dosing, potency, or administration route in humans.
- Sourcing & quality issues: Often obtained as “research chemicals” online; variable purity, stability concerns, no reliable regulation or third-party verification for most users.
ABOUT THE GUEST: Flynn Mcguire, MD is a physical medicine and rehabilitation resident at the University of Utah; he conducts clinical work in neurologic recovery and musculoskeletal care and has authored a narrative reviews on peptides for musculoskeletal healing.
