Welcome to Nofinity

In this video, Dr. Jin Xiong She, an expert on NAD+ and founder of Genfinity Precision Medicine, discusses the latest research on NAD levels in the human body. He debunks common misconceptions and provides practical advice for optimizing NAD levels.

Key Findings on NAD Research

• Age-Related Decline: NAD levels do not decline linearly with age; the sharpest drop occurs between the ages of 20 and 30. After that, the decline is minimal.
• Health Status and Ethnicity: Individuals with health issues and certain ethnic groups (e.g., Asians) often have lower NAD levels than healthy Caucasians.
• Misinterpretation of Studies: Dr. She criticizes the study by Yansen et al., which found no age-related decline in NAD levels, arguing it is flawed due to its narrow age range and overgeneralization.

Methods to Boost NAD Levels

• Nicotinamide (NAM): Ineffective as an NAD precursor—only about a 10% average increase, with 70% of people showing no change.
• NMN and NR: More effective precursors—1,000 mg of NMN or NR can increase NAD levels by 40–50%.
• Optimized Formulations: Dr. She's patented blend of NMN and other ingredients can boost NAD levels by 116% (powder form) or 150% (special formula).
• NAD IV Infusions: Provide a short-term spike in blood NAD but no sustained increase in intracellular NAD—therefore unsuitable for longevity or performance enhancement.

The Ideal NAD Level

• Optimal Range: Between 55 and 80 micromolar (measured in blood using Genfinity's method). A level above 40 micromolar is considered a minimum; values over 100 micromolar are unnecessary and may be harmful (increased risk of vascular inflammation, e.g., from high niacin doses).
• Testing Recommendation: Take a baseline test before starting supplementation, then retest after 3–4 weeks to assess effectiveness. NAD levels drop by about 3% per day without supplementation.

Additional Tips

• The microbiome and lifestyle can influence NAD levels, but data are still incomplete.
• Dr. She emphasizes: "NAD is a micronutrient—you need to supply it regularly, like vitamins."

Summary follows...

• Peter took the phrase from a hedge-fund friend: have strong convictions, but stay ready to revise them when new information emerges.
• He applies this to medicine and science: don’t cling to a thesis; follow the evidence.
• If he wrote his book again in 10 years, he’d expect it to be different – otherwise it would suggest rigidity or lack of scientific progress.

• Sources: new literature, expert conversations on the podcast, and clinical experience with patients.
• Some views become more stable, others more nuanced, and occasionally he makes a complete U-turn.

• Previously, Peter favored the insulin model of obesity: carbohydrate restriction and ketogenic diets seemed the logical fix.
• He spent 3 years in strict ketosis (fasting beta-hydroxybutyrate ~1.8–2 mmol/L) and felt great.
• Now he believes keto works not primarily via insulin suppression, but because it helps control energy intake and increases satiety.
• Energy balance is the key factor; hyperinsulinemia is more a passenger than a driver.
• He’s less dogmatic about which diet patients choose, as long as key principles are met – especially adequate protein (≥1.4 g per kg body weight).

• Peter used to do 7–10-day fasts quarterly, plus 3-day fasts monthly.
• His main motivation was boosting autophagy – cells recycling damaged components.
• The theory: autophagy first targets the “worst” cells, e.g., senescent or mutated ones.
• Autophagy is analog, not a digital on/off switch; marked elevation seems to require about 3 days of fasting.
• His position has shifted due to cost-benefit considerations and evolving evidence.

The host, an experienced trader who lived through the dot-com bubble, discusses topics like the AI bubble, crypto proxies, Solana's burn mechanism, and future prospects. He emphasizes that early investments are crucial and warns against risks in proxies.

• Dot-com Comparison: The dot-com bubble (1995-2000) saw 985% gains in 62 months; the current AI phase (47 months) is up 157% in the index, but the chip sector (e.g., Nvidia, Micron) has risen 345% since November 2022.
• Valuation: Despite the boom, many AI stocks are not overvalued – Nvidia trades at 14x forward earnings, Micron at 5.9x (vs. Cisco's 200x PE in 2000). There’s still $10.3 trillion in AI buildout ahead.
• Phase Estimation: The host believes we're in the middle of the cycle (comparable to 1998), with about 24 months of bull run left. He warns of excesses and advises watching debt, defaults, and slowing growth.

• DeFi Dev (DFDV): Despite a low NAV premium (0.51), the company has high debt ($126M) and dilution of 130.76% since June 2025 – five times more than MicroStrategy. This led to an 89% drop from all-time highs. He advises not to buy leaps on proxies as they get 'completely cooked' due to implied volatility and dilution.
• Smarter Web vs. MicroStrategy: Smarter Web has a NAV premium of 1.37 (vs. 0.74 for MicroStrategy), little cash ($2M), and debt. MicroStrategy is more established (309x more Bitcoin) and safer. Rule: Buy proxies with low NAV premium and watch debt and dilution – not 'death and taxes' but 'debt and dilution'.

• Burn Rate: With 60,000 SOL minted daily, only 434–990 SOL are burned currently. 10 billion transactions per day would burn 1.44% of supply annually, fully absorbing inflation and being bullish. Validators still earn priority fees. New rules (SMD-0550) double disinflation.
• Assessment: Solana becomes scarcer as adoption grows. Long-term, the burn mechanism needs adjustment, but it works for now. Key metrics: adoption (e.g., apps like Jupiter, Backpack) and simple valuations like market cap per transaction.

• Space-Based Data Centers: Marvell lacks radiation-hardened technology, but Tesla/SpaceX work with Intel. Google already sent four TPUs to space – the future is here.
• Investment Strategy: Build 'retire-on-bags' (e.g., 655 SpaceX shares for $1M by 2032) and buy on dips (e.g., Palantir at $106, Nvidia at $88). Q4 will be hot, Q1 often sells off – so be patient.
• Critique of Funds: 550 holdings are nonsense – you lose returns through fees (2 and 20) and lack of transparency. Better invest in pure form (e.g., ETFs, direct stocks).

You are not too late to the party, but much 'juice' has already been squeezed. Proxies are risky – buy them only as lottery tickets. Focus on fundamental strength, low debt, and clear adoption. Be ready for dips and keep cash!

Important: Not financial advice, do your own research.

Summary: The Murder of Becky Bliefnick

• On February 23, 2023, Becky Bliefnick, a 41-year-old mother of three, was found dead in her home in Quincy, Illinois.
• Her father discovered her lifeless body in the bathroom – a devastating scene.

• The perpetrator entered through a forced window in a child's bedroom, kicked in the bedroom door, and shot Becky 14 times with a 9mm pistol.
• She tried to call 911 at 1:11 a.m. but couldn't complete the call.
• A security system shows the front door opened at 1:12 a.m. – the killer fled.

• Becky and her husband Timothy (Tim) Bliefnick had a troubled marriage; Tim filed for divorce in 2021.
• The separation was marked by intense conflict and mutual accusations.
• Becky feared Tim and texted her sister: “If something happens to me, Tim is the first person to look at.”
• The final divorce hearing was scheduled just days after the murder; Becky wanted to prevent Tim's father from having unsupervised contact with the children.

• Surveillance cameras captured an unknown person lurking around Becky's house on nights before the murder, and a cyclist on the night of the crime.
• The bicycle had no reflectors on the wheels.
• Searches of Tim's home yielded incriminating evidence:
  • 27 spent cartridge cases from the same gun used in the murder.
  • Google searches like “How to open a window from outside?”, “How to build a silencer?”, “Can gunshot residue be washed off?”
  • A fake Facebook account used to buy a blue Schwinn bicycle without reflectors.
  • Gaps in his fitness tracker data during the relevant nighttime hours.
  • A crowbar and Aldi plastic bags matching fragments found at the crime scene.

• Tim was charged with first-degree murder and home invasion.
• The prosecution argued that Tim killed his wife out of anger over the divorce and upcoming custody issues.
• The defense pointed to a lack of direct evidence (no DNA, no murder weapon) and suggested the Google searches were made after the murder out of curiosity.
• The jury reached a unanimous verdict after only 4 hours and 15 minutes of deliberation.
• Sentence: Life in prison without parole.

• This case illustrates how a toxic relationship can escalate into deadly violence.
• Particularly chilling: Tim deliberately sent Becky's father to find her body while his own children slept in his home.
• Becky's failed attempt to call for help highlights her final terrifying moments.
• The chain of circumstantial evidence was overwhelming – I believe the verdict was just.

Dr. Martin Picard, director of the Mitochondrial Psychobiology Lab, explains that stress isn't inherently harmful; rather, the capacity for recovery is the key to longevity. The body has an innate healing ability that is activated through rest periods.

• Gray hair is reversible: Graying linked to stress can actually reverse – a visible example of the plasticity of aging.
• Allostatic load: Chronic anticipation of stress consumes energy, leading to wear and tear. The solution isn't avoiding stress but finding intentional rest and regeneration times.
• Focus on mitochondria:
  • Stress (e.g., cortisol) increases cellular energy consumption by up to 60%.
  • Chronic stress diverts energy from repair processes like DNA repair and telomere maintenance, accelerating aging.
  • Hypermetabolism in aging cells drains energy from the body, similar to cancer or sepsis.
• Mind-body connection: Emotions and thoughts directly affect mitochondria – via cortisol, blood sugar levels, and mitochondrial DNA leaks that trigger inflammation.
• Practical steps: Mindfulness, meditation, and exercise help to be present in the moment, enabling healing. The goal isn't a stress-free life, but balancing stress with recovery.
• Marker for mitochondrial stress: GDF15 (growth differentiation factor 15) indicates energetic stress – ideally low at rest.

Dr. Picard encourages proactive rest, not passive stress avoidance. The body heals itself when given the chance – this is the foundation for a healthy lifespan.
