• MOA: An irreversible inhibitor of Tryptophan Hydroxylase (TPH); it stops the body from synthesizing serotonin at the rate-limiting step.
• Unique/Peaty Benefit: Acts as the "ultimate brake-remover" by depleting the systemic serotonin that Peat linked to hibernation, estrogen dominance, and metabolic slowdown.
• Why better than alternatives: While Cyproheptadine or Ketotifen only block serotonin receptors, Fenclonine prevents the production of serotonin itself, providing a much deeper and longer-lasting "reset" of the nervous system.

2. Ketotifen

• MOA: Mast cell stabilizer and H1-receptor antagonist that also blocks serotonin receptors.
• Unique/Peaty Benefit: Lowers the "hibernation" effect of serotonin and prevents the inflammatory release of histamine/leukotrienes in the gut.
• Why better than alternatives: Offers the anti-serotonin benefits of Cyproheptadine but with significantly less brain fog and fewer anticholinergic (drying) side effects.

3. Zinc Carnosine (no need to search for a source just wanted to mention it )

• MOA: A chelated complex that adheres to gastric lesions and stimulates the repair of the epithelial barrier.
• Unique/Peaty Benefit: Directly seals the gut to prevent endotoxin (LPS) from entering the blood and poisoning the liver/metabolism.
• Why better than alternatives: Unlike PPIs or antacids, it heals the stomach lining without suppressing the stomach acid needed for proper protein digestion.

3.1 Zinc Carnosine & Sport-Induced Endotoxemia

the ability of Zinc Carnosine to blunt exercise-induced gut leakiness by ~70% is wild

4. Methazolamide

• MOA: Carbonic anhydrase inhibitor that increases systemic and cellular concentrations of Carbon Dioxide (CO2).
• Unique/Peaty Benefit: Uses CO2 to optimize oxygen delivery to cells and protect against the "excitotoxicity" of glutamate and calcium.
• Why better than alternatives: More lipid-soluble than Acetazolamide, meaning it crosses the blood-brain barrier better and requires a lower, more tolerable dose.

5. Etifoxine

• MOA: Binds to the TSPO protein in mitochondria to trigger the conversion of cholesterol into neurosteroids like Allopregnanolone.
• Unique/Peaty Benefit: Promotes the body’s own production of "youthful" anti-stress steroids (Progesterone/Pregnenolone) in the brain.
• Why better than alternatives: Provides the same anxiety relief as Benzodiazepines (Xanax) but without the addiction, memory loss, or "rebound" stress.
