Andrew Huberman has discussed BPC-157, TB-500, and PT-141 on his podcast, noting their tissue repair and healing potential while consistently emphasizing they are unregulated research compounds requiring physician supervision. He has personally used BPC-157 for injury recovery.
A complete visual breakdown of both Huberman Lab peptide episodes — every peptide, every dose, every warning, with timestamps
This page summarizes two Huberman Lab episodes on peptides — an April 2024 solo deep-dive and an October 2024 expert interview with Dr. Craig Koniver. Together they cover more ground on peptides than almost anything else publicly available. Here's what was said, with timestamps, properly attributed.
Dr. Koniver is a board-certified physician and leading expert in performance medicine. Huberman is a Professor of Neurobiology at Stanford. Both stress throughout both episodes: work with a physician, source clean peptides, and don't replace lifestyle basics. That's the framing for everything below.
Three peptides dominate the healing conversation in both episodes. BPC-157 gets the most airtime — and the most caveats. TB-500 is its frequent stacking partner. PDA is the newer, compounding-legal alternative to BPC.
Huberman says: "Synthetic peptide resembling one naturally found in the gut. Involved in wound healing and repair by aiding tissue repair and cell turnover. Encourages angiogenesis — calling in new blood vessels."
"Anyone who's working out regularly, BPC is going to benefit." — Koniver
"People seem to have a better clinical response to injectable BPC-157." — Koniver on injection vs. oral
Range: 300–500mcg · Start at minimum effective dose
Koniver's protocol: 500mcg/day
Cycle: 5 days on / 2 days off
Route: Subcutaneous or intramuscular injection. Oral BPC appears limited to gut effects only.
⚠️ Risk (Huberman): "Avoid if you have a tumor or cancer. It increases vasculature which can grow tumors."
📋 Note (Koniver): "BPC-157 has been placed on FDA Category 2 list (2023). PDA (pentadeca arginate) is the newer alternative — almost same molecular structure with one amino acid changed."
What it is: "Naturally produced by the thymus gland in children, then disappears. This is why children recover faster with less scarring."
Benefits: Increases rate and thoroughness of wound healing and tissue repair/rejuvenation.
✓ Key distinction: "Does NOT appear to impact the growth pathway — just rejuvenation and repair." Unlike BPC-157 which upregulates GH.
TB-500 is a truncated version of thymosin beta-4 — different mode of action, lasts a bit longer in the body.
Common use: Often stacked with BPC-157 for synergistic healing effects.
Koniver says: "Almost the same molecular structure as BPC-157 but one amino acid is changed."
Why it exists: BPC-157 was pulled from compounding pharmacies by the FDA. PDA is the physician-prescribed alternative — available where BPC-157 is not.
250–500mcg starting dose · Monday through Friday · Weekends off
✓ "No known major side effects to either BPC-157 or PDA." — Koniver
After age 30, growth hormone declines. These peptides stimulate your body's own GH release rather than injecting synthetic GH directly. Huberman breaks them into two distinct categories — and has clear warnings about both.
Huberman's major warning on ALL GH peptides: "Growth hormone is INDISCRIMINATE about which tissue it grows. If you have any tumor, it will grow that too. Avoid ALL GH secretagogues if you have or are concerned about cancer."
"Mimics naturally released GH. FDA-approved for short stature. Taken at night." — Huberman
Benefits: Increases GH, IGF-1, and deep sleep (possibly at the expense of REM).
200mcg+ depending on goals. Wide range — start low.
FDA-approved for visceral fat reduction in HIV patients. Longer-lasting than sermorelin.
Primary effect: Visceral fat reduction.
"Seems to work better on females than males." — Koniver
2mg
"Very long-lasting GH and IGF-1 elevation. Allows GH to stay in system longer." — Huberman
⚠️ "More risks — can increase fluid retention. Had a death in clinical trials."
Common use: Usually combined with ipamorelin to direct GH release timing.
"Most specific but weakest. Helps push out GH and directs when it's released. Best for subcutaneous fat reduction."
Max 100mcg · At bedtime
⚠️ Side effects (flushing) if taking too much.
"Greater GH release than others." — Huberman
⚠️ "Dramatically increases prolactin (low libido, malaise). Can desensitize GH receptors."
Koniver: Also used as energy/endurance peptide — 100mcg in the morning.
"Binds GH, prolactin, AND ACTH. Can cause cortisol spikes and hunger."
Best for: Bulking — the hunger effect makes it counterproductive for fat loss.
100mcg
"Oral version of GHRP-6. Same side effects — dramatically increased GH, prolactin, and cortisol."
"Not what most people are looking for." — Huberman
The protocol: Subcutaneous fat reduction from ipamorelin + visceral fat reduction from tesamorelin + upregulation of GH receptor from BPC-157.
Take between 10pm–2am — that's the window of the largest natural GH pulse.
GLP-1 receptor agonists were originally developed for type 2 diabetes. Now they're the most-prescribed weight loss drugs in history. Koniver's take on how to use them is more nuanced than what you'll see on the news.
Primary example: Semaglutide (Ozempic/Wegovy) — Originally approved for type 2 diabetes. Now FDA-approved for weight loss. The mechanism: reduces appetite and slows gastric emptying, leading to sustained caloric reduction.
"Conventional doses trigger weight loss too quickly. Micro dosing targets about 2 pounds per week. Reduces muscle loss." — Koniver
Why microdose? Conventional doses cause rapid weight loss that burns both fat AND muscle. Slower = more sustainable, less muscle wasting.
Tip: "Take your time dosing to avoid nausea." — Koniver
Huberman on inflammation: "Adipose tissue produces hormones that impact brain function. Body-wide inflammation comes down with weight loss."
"Some patients build healthier lifestyles AFTER losing weight with GLP-1s. If you can get people to feel better, sometimes it helps spur action." — Koniver
Timestamps: Ep2 10:00 · Ep2 1:37:19
These peptides touch hormone pathways and libido. All three carry notable caveats — especially PT-141 and the melanotans, which have narrow therapeutic windows.
"Turns on GnRH → FSH → testosterone → estrogen pathway."
Effect: Increases vitality as it relates to libido and mood.
Also: Suppressing it can alleviate menopause symptoms. — Huberman
"Bolsters immune response AND libido." — Huberman
⚠️ Narrow therapeutic window — "Can cause nausea and orange tanning appearance." Use caution with dosing.
"Stimulates skin pigmentation by activating melanocytes." — Huberman
⚠️ Side effects: Nausea, flushing, increased blood pressure.
⚠️ "Can exacerbate melanoma." — Huberman. Avoid if skin cancer concern.
Two peptides from the pineal gland family — both explored for circadian rhythm, aging, and sleep. Mostly animal data, but Koniver has used them clinically.
"Peptide from the pineal gland. Recalibrates circadian rhythm changes that occur with age." — Huberman
Effects: Anti-inflammatory. Involved in DNA repair. Explored in animal studies for vision loss.
Evidence: Animal studies. Mechanisms being explored.
"Can improve REM sleep. Works especially well combined with glycine. Seems to have circadian rhythm effects." — Koniver
Clinical note from Koniver: Often used alongside glycine for synergistic sleep improvement.
Two standouts from the October episode — one injectable with decades of stroke data, one oral with unexpected cognitive effects.
Koniver says: "Used for decades post-stroke and brain injury. Helps with brain fog and cognition. Collectively increases BDNF."
⚠️ "Can induce depression symptoms for 1–2 days after initial use." — Koniver. Expect this, it passes.
Route: Injectable
"First pharmaceutical approved in the US. Potent oxygenator, anti-viral, cognitive stimulant. Absorbed well orally." — Koniver
10mg in the morning · 3x per week
"Turns tongue blue for 24 hours — if it doesn't, your mitochondria aren't working well." — Koniver
Route: Oral — well absorbed
"If I had to pick one thing for people, engaging in NAD would be it."— Dr. Craig Koniver, MD · Ep2
Koniver breaks NAD+ delivery into a hierarchy — IV is most effective, then injection, then oral. Here's the rundown from the episode.
Loading dose: 750mg
"Works 'almost inexplicably' to go from sick to well quickly." — Koniver
Huberman's anecdote: Recovered from COVID within 48 hours, tested negative after a strong positive.
Maintenance: Monthly dose after loading.
$500–$1,000 per infusion · Can be uncomfortable — some take anti-nausea meds beforehand
"Next best if you can't afford IV infusions." — Koniver
Subcutaneous injection. More accessible price point.
"Next most promising after injections. Helps hair and nails grow fast. Data murky for other uses." — Koniver
"Can reduce inflammation. Less costly but doesn't seem as effective." — Koniver
These aren't disclaimers — both Huberman and Koniver return to these points repeatedly throughout both episodes. They're the frame for everything else.
"Only put peptides into your body that you have gotten from a physician you have met with and is monitoring the dose and response." — Koniver
"Black market peptides are often contaminated with lipopolysaccharide (LPS) which can trigger immune response." — Huberman
"5 days on, 2 days off" — Koniver's standard protocol for most peptides
"Growth hormone and IGF-1 are indiscriminate. You WILL increase the size and vascularization of tumors." — Huberman
Both episodes emphasize minimum effective dose first. Don't start at max dose. Give it time before increasing.
"There's no way to avoid it — peptides act broadly. You WILL activate additional pathways regardless of intended target." — Huberman
"No pill, potion, or injection is going to replace good behaviors but they can augment them." — Koniver
Regular blood panels under physician guidance. Track what's actually changing in your body.
Huberman mentioned these non-peptide supplements during the October episode:
"Mitochondrial health and energy. Can take up to 2,400mg/day. No known side effects. Also helps with migraines." — Huberman
"Lowers homocysteine (cardiovascular risk marker). Instead of more caffeine for afternoon slump, try methylated B." — Huberman
"Calming. Helps transition to sleep. Liver detoxification. Absorbed well orally, up to 10g." — Huberman
On March 25, 2026, Huberman posted a prediction that shook the HRT space: kisspeptin and gonadorelin will be the next peptides to hit mainstream male and female hormone replacement therapy.
"Prediction: the peptides that will hit the broader male and female HRT space next are kisspeptin and gonadorelin (and not in place of HCG!). Will be interesting to see which companies compound for wide distribution first. These are potent and MD monitoring will be key."
— Andrew Huberman, March 25, 2026
This is significant because both peptides work upstream of traditional HRT. Instead of replacing hormones directly, they stimulate your body's own production:
The master upstream regulator — triggers GnRH release, which triggers LH/FSH, which triggers testosterone and estrogen production. Works at the very top of the hormonal cascade. Being studied for both male hypogonadism and female reproductive health.
Read our full Kisspeptin guide →A synthetic GnRH analog that directly stimulates LH and FSH release from the pituitary. Already used clinically for fertility and as an HCG alternative during TRT to maintain testicular function and fertility.
Read our full Gonadorelin guide →Huberman explicitly says these are "not in place of HCG" — they're complementary. HCG mimics LH directly, while kisspeptin and gonadorelin work upstream. The combination may preserve more natural hormonal signaling.
Read our HCG guide →Huberman also appeared on Bill Maher's Club Random podcast (March 23, 2026) discussing peptides, biohacking, and Big Pharma — calling it "separating what's real from what's hype." The mainstream exposure is accelerating interest in these compounds.
After 5+ hours across two episodes, here's the honest summary.

Andrew Huberman has discussed several peptides on his podcast, including BPC-157 (for tissue repair and gut healing), TB-500 (for injury recovery and inflammation), and PT-141 (for sexual health). He approaches peptides with scientific caution, consistently noting they are largely unregulated research compounds and recommending consultation with a physician before use. He has not formally "recommended" any specific peptide protocol for general audiences.
Andrew Huberman has publicly discussed using BPC-157 for injury recovery, specifically mentioning it in the context of healing soft tissue injuries. He described taking it orally and via injection during a period of recovery. However, he consistently emphasizes that BPC-157 is a research compound without full human clinical trial data and that individual use should be supervised by a knowledgeable physician.
Huberman has not published a formal "peptide stack," but has discussed BPC-157 for gut and tissue repair, TB-500 for inflammation and healing, and briefly mentioned growth hormone secretagogues. His Huberman Lab podcast episodes on peptides (notably his discussion with Dr. Craig Koniver) provide the most detailed breakdown of compounds he considers credible. His overall stance is that peptides show significant promise but require careful sourcing and medical supervision.
