In this special guest episode of Chinese Medicine in the Modern World, Dr. Kelly Cmolik sits down with her friend and first-ever podcast guest, Dr. Mary Pines — a PhD biomedical scientist with 25+ years of research experience and founder of Better Beyond 40, a program helping women navigate perimenopause, menopause, and healthy aging.

Together they break down the rapidly growing world of peptide therapy for women over 40: what peptides actually are, how they differ from hormones and nutritional proteins, why GLP-1 medications (like Ozempic and Mounjaro) have reshaped the conversation around weight and metabolism, and how Dr. Kelly integrates peptides into a Chinese medicine framework built around clearing inflammation, rebalancing the body, and tonifying what's deficient.

The conversation covers commonly discussed compounds — KPV, BPC-157, TB-500, GHK-Cu, Thymosin alpha-1, growth hormone secretagogues (tesamorelin, sermorelin, CJC-1295, ipamorelin), and epitalon — along with candid discussion of safety concerns, sourcing, dosing philosophy, and the historical origins of peptide science with Russian scientist Vladimir Khavinson.

In this episode, you'll learn:

  • What a peptide is, and how it differs from a hormone or a nutritional protein like collagen
  • Why peptides are considered more "homeostatic" than blunt-force hormone replacement
  • How GLP-1 medications work, and why irresponsible dosing (not the drug class itself) drove many side effects
  • Why weight loss without addressing muscle, bone density, and detox pathways can backfire
  • How Dr. Kelly integrates peptides into a three-phase Chinese medicine protocol (clear, rebalance, tonify)
  • The difference between FDA-approved GLP-1 drugs and "gray market" investigational peptides
  • Common concerns around BPC-157, angiogenesis, and cancer risk — and the current thinking on that topic
  • The history of peptide science, from Cold War Russia to modern longevity medicine
  • Three questions to ask yourself before starting any peptide protocol

Meet the Guest: Dr. Mary Pines, PhD

Dr. Mary Pines holds a PhD in biomedical sciences from the University of Cambridge, with expertise spanning genetics, biochemistry, and molecular biology. She has worked as a biomedical scientist for 25 years, published peer-reviewed research in Cell and Nature Cell Biology, and was named Postdoctoral Researcher of the Year by UBC's Department of Cell and Physiological Sciences. She has more than a decade of experience helping women with health and longevity and is the founder of Better Beyond 40, a program supporting women through perimenopause, menopause, and healthy aging using a lens of hormones, metabolism, and longevity.

Find her atdrmarypines.com, on YouTube, Instagram, and Facebook, and via her own podcast, Better Beyond 40.

Key Takeaways

  1. Peptides are short chains of amino acids (roughly 2–50), distinct from large structural proteins (like collagen) and from hormones. The episode focuses on "signaling" peptides — molecules the body naturally produces that decline with age.
  2. Peptides act more like a targeted signal than a hormone. Dr. Pines describes hormones as "loudspeakers" reaching many systems at once, while peptides send more precise, localized signals.
  3. A key appeal of peptides is their built-in regulatory mechanism. Unlike a blunt-force approach (e.g., taking growth hormone directly), peptides are described as working with the body's existing homeostatic systems rather than overriding them.
  4. Dr. Kelly frames peptides as an adjunct — not a replacement — for root-cause Chinese medicine work. Her clinical approach layers three phases: (1) clearing inflammation and underlying pathogens, (2) rebalancing digestive, metabolic, and organ function, and (3) tonifying/bolstering systems that are deficient, especially with age.
  5. On GLP-1 medications (e.g., Ozempic, Mounjaro): Dr. Pines argues that many reported side effects (nausea, gastroparesis) stemmed from aggressive, high starting doses rather than the drug class itself — she advocates starting low and titrating slowly.
  6. GLP-1s are positioned as a tool for people already doing "the right things" — lifestyle, nutrition, and movement — who are still experiencing weight-loss resistance, rather than a replacement for foundational habits.
  7. Rapid weight loss carries real risks beyond muscle and bone loss, including the release of toxins stored in fat tissue. Dr. Kelly emphasizes supporting elimination pathways (hydration, fiber, bowel regularity) during any rapid metabolic shift.
  8. A DEXA scan (body composition scan) is recommended before and during use of GLP-1s or other metabolic-support peptides to monitor bone density and muscle mass.
  9. Investigational/"gray market" peptides are not automatically unsafe — Dr. Pines distinguishes regulatory status (patentability, FDA approval) from actual safety evidence, citing decades of international clinical use, mechanistic research, and preclinical data for peptides that lack large-scale randomized trials in North America.
  10. BPC-157 and cancer risk is a frequently raised concern. Dr. Pines states that current evidence does not support the idea that BPC-157's angiogenesis-related effects promote tumor growth, distinguishing regulated, healing-related blood vessel formation from tumor angiogenesis. (See editorial note below — this is a claim from the guest that should be verified before publishing without qualification.)
  11. Peptides discussed for inflammation/immune modulation: KPV, Thymosin alpha-1.
  12. Peptides discussed for tissue repair/recovery (informally called the "Wolverine stack"): BPC-157 and TB-500.
  13. GHK-Cu (copper peptide) was discussed in relation to connective tissue, skin, hair, and nails.
  14. Growth hormone secretagogues mentioned: tesamorelin, sermorelin, CJC-1295, ipamorelin — associated with muscle, sleep, and body composition support.
  15. Epitalon (a pineal gland peptide) was discussed in relation to circadian rhythm support, particularly for frequent travelers and shift workers.
  16. Peptide stacking and protocol length: Dr. Pines describes typically combining two to three peptides, with protocols commonly running around 12 weeks (sometimes shorter or longer depending on the case).
  17. Historical origin: Peptide science is credited to Russian scientist Vladimir Khavinson, whose Cold War-era research (originally aimed at accelerating soldier recovery) led to the discovery of compounds including BPC-157 and a broader class of short bioregulator peptides.
  18. Three questions before starting any peptide: (1) What do you actually want to accomplish, and how will you know it's working? (2) Have you addressed the foundational lifestyle factors first? (3) What else are you doing to support the outcome you want?


⚠️ Editorial Notes for Review Before Publishing

A few items in this interview involve specific medical/safety claims about peptides (an area with active debate and limited regulatory approval in North America). Flagging these for your review before they go out in published show notes or marketing copy:

  • BPC-157 and cancer/tumor risk: Dr. Pines states there is "zero evidence" linking BPC-157 to tumor promotion. This is a contested area even within the peptide community, and framing this definitively in public-facing content could carry liability or credibility risk. Recommend either attributing this explicitly as Dr. Pines' clinical opinion (as done above) or softening the language.
  • Specific dosing philosophy ("microdose then titrate") is mentioned in general terms but no actual dosages are given — good, but worth...
