Huberman Lab provides the episode transcript, timestamped topic list and cited journal articles on the official episode page. Those materials support the compound names and summaries below. The transcript is incomplete around the final kisspeptin segment, so that entry is limited to what the official timestamped notes establish. This article omits dosing and is not a protocol.
Compounds discussed in this episode
Speaker claims below are paraphrases, not endorsements or quotations. Scientific context is separated from the speaker's experience or opinion.
01BPC-157
What the speaker said
Huberman described animal findings involving blood vessels, fibroblasts and injured tissue, while emphasizing that rigorous human evidence was missing. He also raised theoretical angiogenesis and tumor concerns. His discussion was an evidence-qualified explanation, not a clinical endorsement.
Scientific Context
Tendon, muscle and gastrointestinal findings are largely preclinical. Mechanistic plausibility cannot establish human benefit or long-term safety, and BPC-157 has no FDA-approved therapeutic indication.
Where to buy for laboratory research
BPC-157 at Base Peptides — verified exact-name product page. This editorial listing is not a guest endorsement and is not a recommendation for human use.
02Thymosin beta-4
What the speaker said
Huberman discussed full-length thymosin beta-4 in tissue repair before addressing the related product commonly called TB-500. The distinction matters because they are not automatically the same molecular material.
Scientific Context
Thymosin beta-4 has biologic roles in actin dynamics and repair, with experimental and limited clinical research in selected settings. Those data do not validate retail TB-500 for injury recovery.
Where to buy for laboratory research
No verified exact full-length thymosin beta-4 product page was found at the named suppliers. TB-500 is not substituted here. No substitute or near-match is linked.
03TB-500
What the speaker said
The episode treated TB-500 as a thymosin beta-4-related fragment used in the peptide market and discussed claimed repair applications with caution. Huberman did not present it as proven equivalent to the full-length molecule.
Scientific Context
Identity and nomenclature are inconsistent across the market, and controlled human recovery evidence is lacking. Findings for full-length thymosin beta-4 should not be silently transferred to TB-500.
Where to buy for laboratory research
TB-500 at Base Peptides — verified exact-name product page. This editorial listing is not a guest endorsement and is not a recommendation for human use.
04Sermorelin
What the speaker said
Huberman included sermorelin among growth-hormone-releasing hormone analogues and explained that secretagogues stimulate endogenous signaling rather than supplying growth hormone itself. He also discussed class-level endocrine risks.
Scientific Context
Sermorelin has a history as a diagnostic/therapeutic GHRH analogue, but broad anti-aging, performance and body-composition uses are not established FDA-approved indications.
Where to buy for laboratory research
Sermorelin at Base Peptides — verified exact-name product page. This editorial listing is not a guest endorsement and is not a recommendation for human use.
05Tesamorelin
What the speaker said
Tesamorelin appeared in the GHRH/secretagogue section. Huberman distinguished compounds with a defined medical use from generalized wellness claims.
Scientific Context
Tesamorelin is FDA-approved for reduction of excess abdominal fat in adults with HIV and lipodystrophy. That specific indication does not establish routine weight-loss, bodybuilding or longevity use.
Where to buy for laboratory research
Tesamorelin at Base Peptides — verified exact-name product page. This editorial listing is not a guest endorsement and is not a recommendation for human use.
06CJC-1295
What the speaker said
Huberman discussed CJC-1295 with growth-hormone secretagogues and the consequences of elevating GH/IGF-1 signaling. The official topic label does not resolve DAC versus no-DAC as a product recommendation.
Scientific Context
Small early studies show prolonged GH/IGF-1 effects for DAC-linked CJC-1295, but meaningful clinical benefit and long-term safety for wellness uses are not established.
Where to buy for laboratory research
The episode mention is not an exact product-form match. Base Peptides' verified listing is specifically CJC-1295 DAC, so it is not linked as a substitute for an unspecified CJC-1295 mention. No substitute or near-match is linked.
07Ipamorelin
What the speaker said
Huberman grouped ipamorelin with ghrelin-receptor growth-hormone secretagogues and discussed endocrine effects and risks rather than offering it as a general protocol.
Scientific Context
Pharmacology studies support GH-releasing activity, but that is not the same as demonstrated improvement in recovery, muscle, sleep or longevity outcomes. It lacks an FDA-approved wellness indication.
Where to buy for laboratory research
Ipamorelin at Base Peptides — verified exact-name product page. This editorial listing is not a guest endorsement and is not a recommendation for human use.
08Hexarelin
What the speaker said
Huberman placed hexarelin among the more potent growth-hormone-releasing peptides and warned about prolactin elevation and receptor desensitization. He repeatedly directed listeners toward physician monitoring rather than self-experimentation.
Scientific Context
Endocrine activity is documented, but anti-aging and performance outcomes are not established, and increasing a hormone is not itself a patient-centered clinical benefit.
Where to buy for laboratory research
No exact Hexarelin product page was verified at Base Peptides or Peptide Stock at review time. No substitute or near-match is linked.
09GHRP-2, GHRP-3 and GHRP-6
What the speaker said
The transcript names all three together as GH-releasing peptides. Huberman highlighted possible cortisol and prolactin increases, using GHRP-3 as the example in the transcript.
Scientific Context
These compounds should not be treated as interchangeable despite their shared class. Clinical utility for general wellness is unproven, and endocrine side effects complicate any inference from short-term GH release.
Where to buy for laboratory research
No exact matching product pages for these three individually were verified at the named suppliers. No substitute or near-match is linked.
10MK-677 (ibutamoren)
What the speaker said
Huberman included oral MK-677 in the same functional discussion as GHRPs and warned about cortisol and prolactin effects.
Scientific Context
MK-677 is a non-peptide small-molecule ghrelin-receptor agonist. It is included because the episode names it, but it should not be mislabeled as a peptide or an approved anti-aging drug.
Where to buy for laboratory research
Unavailable in this peptide-product section because MK-677 is not a peptide. No substitute or near-match is linked.
11Epitalon (Epithalon)
What the speaker said
In the longevity section, Huberman covered Epitalon claims around telomeres and aging while stressing the limited quality and geography of much of the evidence.
Scientific Context
Cell, animal and small human reports do not establish lifespan extension or a favorable long-term risk-benefit profile in humans. It is not an FDA-approved longevity treatment.
Where to buy for laboratory research
No live exact Epitalon/Epithalon product page was verified at Base Peptides or Peptide Stock at review time. No substitute or near-match is linked.
12Melanotan I–V
What the speaker said
Huberman described a five-member Melanotan group, distinguishing Melanotan I's limited brain penetration from the mood, appetite and libido effects he attributed to later members. This was a class explanation, not an endorsement.
Scientific Context
Nomenclature and regulatory status differ across melanocortin analogues. Unlicensed tanning injections carry product-quality and safety concerns; class-level discussion cannot establish that every numbered analogue is safe or effective.
Where to buy for laboratory research
No links are provided because the episode discussed a family of distinct analogues and no exact family-wide product match exists. No substitute or near-match is linked.
13PT-141 (bremelanotide)
What the speaker said
Huberman identified PT-141 with the prescription drug Vyleesi and discussed its melanocortin pathway, approved population and off-label use in men.
Scientific Context
Bremelanotide is FDA-approved for acquired, generalized hypoactive sexual desire disorder in certain premenopausal women. Off-label anecdotes do not expand the approved evidence base.
Where to buy for laboratory research
No research listing is linked because the episode discussed an FDA-approved prescription active ingredient. No substitute or near-match is linked.
14Kisspeptin
What the speaker said
The official timestamped show notes include a dedicated vitality segment for kisspeptin. The currently published transcript text available to this review did not include a corresponding full passage, so no more specific speaker claim is attributed.
Scientific Context
Kisspeptin has legitimate reproductive-endocrinology research, but a show-note mention alone cannot support a therapeutic or enhancement claim.
Where to buy for laboratory research
No exact Kisspeptin product page was verified at Base Peptides or Peptide Stock at review time. No substitute or near-match is linked.
