WHY MIXING PEPTIDES IN THE SAME SYRINGE BREAKS THE RULES OF PHYSICS AND BIOLOGY
Peptides are often treated like supplements you can stack for convenience. One for repair, one for metabolism, one for inflammation. That mindset leads people to assume they can simply mix peptides in the same syringe and inject once. The problem is peptides are not pills. They are fragile, information-carrying molecules whose behavior is governed by physics, chemistry, and biology at the same time. A peptide is not just a chain of amino acids. In solution it exists as a three-dimensional structure held together by weak forces like hydrogen bonds, electrostatic interactions, and hydrophobic effects. These forces are highly sensitive to the environment. Small changes in pH, ionic strength, or solvent conditions can change the peptide’s shape, stability, and behavior. When a peptide is manufactured, it is stabilized in a very specific formulation. That formulation controls pH, charge, ion balance, and solubility so the peptide stays folded correctly and remains biologically active. When you mix two peptides together, you destroy that controlled environment and create a new, untested chemical system. One of the first things that goes wrong is charge balance. Peptides carry electrical charge depending on pH. That charge helps keep molecules from sticking to each other. Mixing peptides can shift pH just enough to reduce repulsion between molecules. When repulsion drops, attraction wins, and peptides begin to stick together. Ionic strength matters too. Mixing solutions often increases ion concentration, which compresses the electrical “buffer” that keeps peptides apart. This allows molecules to drift close enough for hydrophobic regions to interact. Water dislikes exposed hydrophobic surfaces, so peptides clump together to lower free energy. This is basic solution physics. Once aggregation starts, it accelerates. A few misfolded molecules form a nucleus, which seeds further aggregation. Early clumps may be invisible, but they still matter. They reduce the amount of active peptide, alter absorption, and change signaling behavior.

Nooo 😥 should i. Throw to the bin my klow?😥
Hacked ?
Has Anyone else received DM from Anthony that might seem like he has been hacked? I received one and the location of the message was from Lagos, Nigeria and discussing Crypto currency. I would hate to lose this site because I love Anthonys information.

Choosing The Right Ketone
I get asked often about why I am so partial to Kenetik Pro or Ke4 over other forms of ketones. I thought I would do a short primer on this topic to help everyone better understand. 1. Delta G (D-BHB only) D-β-hydroxybutyrate in powder or liquid form. Instant BHB in your blood—peaks ~1–2 mM in 30–60 min. Fast energy for brain and muscle, but levels crash back by 2–3 hrs. No extra fuel source once it clears. 2. Ketone IQ (1,3-Butanediol only) 1,3-butanediol (BD) that your liver turns into D-BHB.• Metabolism: BD → alcohol dehydrogenase → D-BHB over 1–4 hrs. Peak ~1.5–2 mM. Slower, lower ketone rise; minimal GI issues or electrolytes—but no immediate spike, so it can feel underwhelming. 3. Medium-chain triglycerides (C6–C10 fats).• Metabolism: Goes straight to liver, β-oxidized to acetyl-CoA, then partially converted to BHB over 2–4 hrs. Peak ~0.3–0.6 mM.• Effects: Gentle, sustained mild ketosis. But high doses (>30 g) often cause cramps, diarrhea, and only low-level ketones. 4. Dual Ester (Kenetik Pro or KE4: D-BHB + 1,3-Butanediol in one molecule) A single compound that, when digested, releases free D-BHB immediately AND 1,3-BD for later conversion.Immediate D-BHB spike to ~3–5 mM in 30–60 min.– 1,3-BD portion converts to more D-BHB over the next 2–4 hrs, sustaining levels at ~2–3 mM for 4–6 hrs.– No mineral load, neutral pH, minimal gut upset. Dual-phase ketonaemia—fast AND long.– Trains your own ketone-burning machinery (upregulates BDH1/SCOT).– Clean fuel with zero electrolyte drama and near-instant mental/physical boost. The reason I choose the Kenetik Pro or Ke4 is because with the combination of fats + sustained you get a turbo-boost spike AND a steady cruise, all from one dose.They are clean with no sodium/potassium dump like salts, no stomach revolt like high-dose MCT.They leave blood pH and electrolytes untouched Using them regularly improves your cells’ ability to burn ketones long-term. These are the staple of my supplementatoin. If you want the highest, quickest, and longest-lasting ketone lift—without cramping, gut issues, or electrolyte headaches—grab the dual-ester formula (Kenetik Pro or KE4). It’s simply the gold standard for peak performance, brain power, and metabolic flexibility. If your interested in learning more about them I highly recommend the book 4th Fuel by Travis Kristofferson. Do you use Ketones? Which ones?

@Anthony Castore i keep deep diving into ketones since i joined here 😂 I’d like to understand the long-term use of ketone monoesters. Specifically, what physiological and metabolic adaptations occur with chronic exposure, and whether the regulatory systems involved in the NAD⁺/NADH redox balance become dependent on exogenous ketones over time. Is there a risk that endogenous redox signaling or metabolic flexibility becomes downregulated, or can ketone monoesters induce durable benefits that persist even after discontinuation?
New Year Check In 👇🏼
Quick check in for the new year Did everyone start working on their fitness goals yet? If so, what are you focused on this year fat loss, muscle gain, strength, conditioning, consistency, or overall health? Drop your goals below. Accountability matters, and it’s always motivating to see what everyone’s pushing toward. For me: I’m finishing my cut over the next 4–6 weeks, then taking advantage of improved insulin sensitivity with a 6 week lean mass rebound, followed by a dedicated health phase to solidify progress. I already started. That old “I’ll wait until Monday” mindset is gone at that point it’s just procrastination. The best time to start was yesterday. The next best time is today!

Part 2 Sleep, Rewritten: Why Kids Sleep, Adults Don’t, and How to Restore the Signal
Light is not just something you see. Light is information. It tells every cell in your body what time it is, what hormones to release, what genes to express, and what state to prepare for. Before food, before supplements, before sleep routines, light is the primary organizer of human biology. Children live in a world where light signals still make sense. Adults do not. A child’s day usually begins with natural light or at least a gradual increase in brightness. Their eyes receive a clear signal that morning has arrived. Cortisol rises smoothly. Body temperature climbs. Appetite turns on. Movement follows. As the day goes on, light exposure naturally peaks and then fades. By evening, darkness arrives without negotiation. The signal is clean. The system knows what to do. Adults live in a different reality. They wake up in darkness. They turn on overhead lights that mimic noon at 6am. They stare into phones inches from their face. They spend most of the day indoors under artificial lighting that never changes. Then, late at night, when biology expects darkness, they flood their eyes with bright screens again. From the brain’s perspective, this is chaos. Circadian rhythm is often described like a clock. That metaphor is misleading. A clock keeps time even if the environment is wrong. Circadian rhythm is more like a conductor leading an orchestra. If the conductor is confused, the musicians don’t just play late. They play out of sync. Light is the conductor. The master clock in the brain, the suprachiasmatic nucleus, does not care what time your phone says it is. It cares what your eyes report. Specialized cells in the retina measure brightness, wavelength, and timing. They send that information directly to the brain’s timing center. From there, signals cascade to hormones, metabolism, digestion, immune function, body temperature, and sleep-wake cycles. This system evolved under one condition only. Bright light during the day. Darkness at night. There was no evolution for indoor lighting, night screens, or social schedules that shift daily. Biology assumes consistency. Modern life provides variability.

@Anthony Castore very good post! But how do you get exposure to light in cold and cloudy climates? Or if your schedule and work don’t allow it?
