Most oral peptides are digested by the stomach and degraded before reaching systemic circulation, which is why people use injectable peptides most of the time; oral capsules should generally be avoided.

Popular growth hormone-releasing peptides like ipamorelin, CJC1295, and sermorelin trigger pulses in growth hormone release, leading to increased muscle mass and strength.

You must know your goal before picking a peptide, because peptides have different functions including muscle growth, strength, weight loss, emotional bonding and love, sleep, and skin tanning.

Just because a doctor doesn't take insurance doesn't mean they don't care about your health outcomes (e.g., preventing heart attacks); it means they can have more honest conversations about your priorities.

NAD stands for nicotinamide adenine dinucleotide and is present in every cell of your body, where it powers the mitochondria—the tiny engines in cells that produce energy.

Most peptides are not FDA approved and human data on them is sparse; the speaker, despite being a doctor, cannot legally prescribe most peptides.

The viewer should not accept claims like 'NAD is a miracle' or 'peptides are the answer' at face value; instead, they should do their own research, read scientific articles if they can understand them, and fact-check popular claims made by influencers on YouTube.

As you age, NAD levels decline, especially after age 40–50, and declining NAD with age leads to more fatigue, brain fog, slower recovery, and the aging process itself.

Declining NAD levels have been heavily researched in the development of dementia, and studies on mice have shown that supplementing with NAD can boost their memory and prevent dementia.

The benefits of NAD supplementation appear to come from lowering oxidative stress, reducing inflammation, and boosting mitochondrial health.

NAD supplementation can be delivered via IV infusions (which boost levels the best and fastest), oral precursors like NMN, or injections.

People who try NAD report a boost in clarity and energy, or sometimes even better sleep, and the effect can last for days, but it does not last forever, analogous to how unplugging a phone does not allow the battery to stay charged forever.

We do not yet know if supplementing with NAD actually slows down the aging process, though research is pretty promising.

Peptides are chains of amino acids (the building blocks of proteins) that act as messengers: they enter the body, find a receptor they fit into, and when they bind to that receptor, they signal a chain of downstream events.

Most peptides are labeled 'research use only' and carry disclaimers that the product is not for human or animal consumption of any kind, despite being marketed for human wellness use.

If you want fat loss or strength gains from peptides, you have to do the work (exercise, diet, etc.) while using the peptide for the result to come; peptides are not magic.

NAD IV infusions cost $200–$500 per session, depending on frequency desired.

Oral NAD precursors like NMN cost $30–$60 per month, making them much less expensive than IV infusions.

Peptide vials typically cost $100–$300, depending on the peptide and vendor; shop around for better pricing.

NAD is best suited for immediate energy needs (e.g., 'I need energy now'), while peptides are better for long-term outcomes like strength gains and fat loss.
