- 2:33From anesthesiology to regenerative medicineCook explains how ultrasound-guided nerve work led him to functional medicine and then to injecting PRP, peptides, stem cells and exosomes around joints and nerves.
- 9:22A staged path to optimizationCook says to begin with lifestyle, then gather baseline labs and wearable data. He describes an AI platform being built to track peptides, exosomes and other interventions.
- 15:09What peptides are and why use themCook defines a peptide as a short protein that binds a receptor. He argues this gives a lower side-effect profile than drugs and says peptides can be matched to each organ system.
- 18:25Immune peptides as the top categoryCook calls immune peptides the most impactful group and describes using them during travel or at the first sign of a cold. He says peptides last about a day and are not taken daily.
- 21:10A peptide stack for ADDCook describes combining SS-31, NAD, a BDNF-raising peptide and thymosin alpha-1 or BPC-157, and says it outperforms stimulants for mental clarity.
- 24:34BPC-157 and TB-500 togetherThe two discuss the pairing for pain, inflammation and connective tissue, including injecting near a sore spot or elsewhere for a systemic effect.
- 27:11Cognition and the gut-brain linkCook describes a peptide that raises BDNF and argues gut inflammation feeds brain inflammation. Brecka then tells of his mother's cognitive change on cerebrolysin.
- 30:53Stem cells, exosomes and inflammationCook describes stem cells as signaling cells that release exosomes. He says exosomes calm inflammation and he and Brecka both report feeling clearer and sleeping better.
- 39:31Follistatin gene therapy and its safetyCook explains a plasmid that lets cells make follistatin for about a year and a half. He cites a Honduran physician's 250 patients with no negative effects except an LDL rise of about 10 points.
What the video says
Host Gary Brecka talks with Dr. Matt Cook, who moved from anesthesiology into functional and regenerative medicine. The episode is a broad longevity discussion. The peptide section is the core of it, and it then extends to stem cells, exosomes and gene therapy.
Cook describes a staged approach. He says people should start with low-cost lifestyle basics, then collect baseline data from labs and wearables, and only then add peptides and other biologics. He explains peptides as short chains of amino acids that bind receptors, and argues they carry fewer side effects than drugs because they supply something the body already uses. Brecka says his clinics have used them with well over 100,000 patients with virtually no side effects, and that the downside is that they sometimes do not work.
Cook says the most impactful category is immune peptides, which he describes as more significant than growth hormone or tissue-repair peptides. He says he and his wife take them when traveling or when a cold starts, and that a cold then lasts a day and a half instead of 10 days. He also describes a stack for people with attention problems, built around SS-31, NAD, a BDNF-raising peptide and thymosin alpha-1 or BPC-157, and claims it beats stimulants. The pair also discuss BPC-157 with TB-500 for connective tissue, and Brecka shares an account of his mother's cognitive change on cerebrolysin.
In the second half Cook explains stem cells as signaling cells that release exosomes, which he says calm inflammation. Both men describe feeling clearer and sleeping better after exosomes. They finish with a plasmid-based follistatin gene therapy offered in Honduras, where Cook says a physician followed 250 treated people and saw no negative effects beyond a rise in LDL of about 10 points. All of this is anecdote and clinic experience, and parts of the episode are sponsor reads.
On each compound
BPC-15724:34
Cook describes BPC-157 as a gastrointestinal peptide that he pairs with TB-500 for pain and inflammation. He also says it promotes blood vessel growth and thins blood viscosity when given by IV. Brecka says he uses it too.

Cook calls TB-500 an immune peptide derived from a thymus fragment and says it tends to help connective tissue. He says it is combined with BPC-157 and can be injected near a painful site or elsewhere for a systemic effect.

Cook says he often adds a little thymosin alpha-1, written as TA1 in the captions, for people with attention problems and immune overactivation. He describes it as a way to regulate the immune response.

Cook says he uses SS-31 to stabilize mitochondrial membranes, as part of a combination aimed at cognitive function in people with ADD.
See how your DNA reads SS-31NAD+22:00
Cook says NAD donates electrons in the mitochondrial chain and so supports energy. He pairs it with SS-31 and a BDNF-raising peptide.
See how your DNA reads NAD+Semax27:11
The captions render the name as "cmax", which appears to be Semax. Cook calls it the best commercially available cognitive peptide and says it raises BDNF.

Brecka says his mother had a dramatic cognitive change within weeks of starting cerebrolysin, first by injection and now as an oral version. This is his family anecdote, not a study.

Cook explains that follistatin is a 344-amino-acid protein and that a plasmid gene therapy lets the body produce it for about a year and a half. He says it blocks myostatin and has anti-inflammatory effects, and Brecka cites a friend's muscle gain.

- No clinical trial, control group or published data is presented, so claims such as colds shortening from 10 days to a day and a half rest on Cook's own experience.
- The ADD and stimulant comparison is Cook's opinion, and no outcomes, doses or patient numbers are given for the peptide stack.
- The safety claims for peptides come from the clinicians' own practices, and neither speaker discusses long-term monitoring or quality control of the products.
Questions this video answers
What does Dr. Matt Cook say about immune peptides?
Cook says immune peptides are the most impactful peptide category, more so than growth hormone or healing peptides. He says he takes them when traveling or at the start of a cold, and claims a cold then lasts a day and a half instead of 10 days.
Why do BPC-157 and TB-500 get used together?
Cook describes BPC-157 as a gut peptide with anti-inflammatory effects and TB-500 as an immune peptide that tends to help connective tissue. He says the combination is very helpful and can be injected locally or systemically. Brecka calls it a tag team used for pain and inflammation.
Does Cook say peptides can replace ADHD stimulants?
Cook says a stack of SS-31, NAD, a BDNF-raising peptide and thymosin alpha-1 or BPC-157 gives better mental clarity than a stimulant, and that he beats stimulants every day. This is his clinical impression and the video presents no data.
What do the speakers say about peptide safety?
Cook says peptides have about an order of magnitude fewer side effects than drugs. Brecka says his clinics have used them in well over 100,000 patients with virtually no side effects, and that the main downside is that they sometimes do not work.
What does Cook say about the follistatin gene therapy?
Cook says a plasmid carrying the follistatin gene is injected and read by cells for about a year and a half without joining the chromosomes. He says a Honduran physician followed 250 treated people and saw no negative effects except an LDL rise of about 10 points, and he calls the field very early.
