Your brain runs on glucose or ketones. On glucose alone, focus rises and falls with your blood sugar — the mid-morning sharpness, the post-lunch fog, the late-afternoon scramble for another coffee. Ketones are the steadier fuel your brain actually prefers under load, and most people almost never reach them. Locked Cognition delivers them directly. Each shot pairs 10g of liposomal R3HBG — a bioidentical form of beta-hydroxybutyrate (BHB), the same ketone your body makes — with Alpha-GPC and Lion's Mane for sustained, calm focus. R3HBG is the first bioidentical ketone recognised by the US FDA as a New Dietary Ingredient, and the liposomal delivery is built to survive digestion and cross the blood–brain barrier, so more of what you take actually gets used. I brought Tecton into the store because it solves a problem most ketone products don't: clean delivery without the synthetic 1,3-butanediol precursors, mineral salt loads, or GI distress that make other exogenous ketones hard to use daily. This is the one I reach for on long writing and recording days. What Locked Cognition supports Sustained focus — steady ketone fuel through long stretches of mental demand, without stimulants Clear thinking — efficient cerebral energy for complex, high-pressure work Mental endurance — built for long workdays, deep work, and back-to-back meetings Consistent output — even energy with no jitter and no crash What's in it Liposomal R3HBG ketone — 10g. Bioidentical BHB delivered directly into circulation. No liver conversion, no mineral loading. Alpha-GPC. A choline source that supports acetylcholine, the neurotransmitter behind focus and recall. Lion's Mane. Traditionally used to support cognition and nerve health. No artificial sweeteners. No synthetic precursors. No BPA. Keto-friendly, clean label. Flavour: Orange Pineapple Crush. How to use Take one shot when you need to lock in — before deep work, a long meeting block, study, or any cognitively demanding stretch. Works with or without food, and pairs cleanly with fasting or lower-carb days. No coffee required. The science, and the people behind it Tecton was co-founded by Dr Kevin Foley, neurosurgeon, Chairman of the Semmes-Murphey Clinic and Professor of Neurosurgery at the University of Tennessee. R3HBG was developed for long-term human use — the cleanest ketone delivery format available. Hear it from the founder I sat down with Tecton founder Mike Chesne on Pushing The Limits to unpack the science of bioidentical ketones, liposomal delivery, and why most exogenous ketones fall short.
