In a Nutshell

Dr. Abud Bakri explains that peptides like BPC-157, Pinealon, Epitalon, GHK-Cu, and thymosin variants show promising regenerative, neuroprotective, and immune-modulating effects in animal studies and anecdotal human use, but most lack robust human trials, known receptors, or established safety data such as LD50 values. Regulatory status is shifting—BPC-157 was recently removed from the FDA's "do not compound" list but remains unapproved—while compounding pharmacies, research-chemical sites, and gray-market sources create inconsistent quality and legal risks for users. The most practical takeaway is that peptides require physician oversight, lab monitoring, and foundational health practices first, as stacking them (e.g., GLP-1s + growth hormone secretagogues + androgens) can accelerate fat loss and recovery but carries unknown long-term risks, especially for cancer, hormonal disruption, and sourcing contamination.

People are now stacking their GLP-1 as their insulin sensitivity tool, their growth hormone or their GHR, and their androgen modulation therapies as this trinity stack to get very fit and very healthy quickly. A lot of transformations seen in CEOs and celebrities use a combination of those three things. TRT plus peptide or retatrutide, then using a growth hormone modulation whether growth hormone or tesamorelin. People lose a lot of fat and gain a lot of muscle in short amounts of time.

Welcome to the Huberman Lab podcast where science and science-based tools for everyday life are discussed. Andrew Huberman is a professor of neurobiology and ophthalmology at Stanford School of Medicine. Today's guest is Dr. Abu Bakri, an internal medicine physician extremely knowledgeable on the science and use of peptides. Peptides discussed include FDA-approved peptides such as the GLP agonists (Ozempic, Mounjaro, and retatrutide) as well as peptides such as body protection compound 157 or BPC-157.

BPC-157 has a very long history of being used in humans for gut health and tissue repair. There are many interesting studies in animals supporting its potential use in humans, but a minimum of formal studies in humans (one). Growth hormone secretagogues like tesamorelin, MK-677 and others are discussed. GHK copper is used to promote collagen synthesis and repair for aesthetic reasons like improving skin and hair. Peptides studied for DNA repair and longevity like epitalon and pinealon have also been touted to improve REM sleep and cognitive function.

What is known and not known about these peptides is explored in terms of function and safety. Dr. Bakri has encyclopedic knowledge about these peptides. Thinking about peptides is based on whether or not they have known receptors, which is very important for their real safety profiles and particular concerns when considering using peptides of any kind. Dr. Bakri comes at this topic through the lens of a physician but is also very interested in the current status and future of peptide medicine.

Peptides are one of the languages of the human body. The body uses different languages to communicate between cells going from DNA to RNA to proteins which can be broken down as polypeptides and peptides. Steroid hormones are another language. Peptides can be broken down further into subcategories based on whether or not they have receptors or have no receptor, which changes the clinical effects. GLP-1s have a very strong clinical effect compared to obscure peptides like BPC-157, TB-500, TB-4 that don't have a clear target. They have receptors but many of them, or they don't even have receptors identified for BPC-157 or TB-4.

There is a distinction between peptides with known receptors like the GLPs and peptides that do not have known receptors but can impact biology in interesting ways based on animal data. BPC-157 might have an elusive receptor or could be modifying certain proteins that already exist or linking different proteins together in a more favorable fashion for gene transcription. Russian peptides are all epigenetic modifiers that bind to the groove of the DNA in certain spots that either open up or close the chromatin to certain areas of genetic expression. They have been modeled like a steroid hormone where steroid hormones bind to a receptor like the androgen receptor binding DHT or testosterone goes into the nucleus and turns on androgenic genes. Pinealon shuttles heat shock proteins with androgen receptors.
