Unlike hyperbaric chambers which vasoconstrict and push more oxygen in, CO2 paste vasodilates blood vessels and leverages the Bohr effect to deliver oxygen already in the blood into tissue more effectively.

The recovery technology discussion opens with Kula establishing his non-negotiable foundation: sleep and nutrition come first, everything else is enhancement. From there, he introduces the audience to Air Therapeutics and their CO2 delivery system — a paste applied directly to targeted areas and a full-body suit that replaces oxygen with CO2 for systemic effects. [1] — Brian Kula "Hyperbaric chambers push more oxygen into the body but vasoconstrict, limiting blood flow. CO2 paste does the opposite — it vasodilates and…" 40:54 The mechanism is the Bohr effect: elevated CO2 causes hemoglobin to release oxygen more readily into surrounding tissue, driving improved cellular repair without the need for pressurized environments. Kula contrasts this directly with hyperbaric chambers, which vasoconstrict while pushing in more oxygen — a combination he argues is less effective because more oxygen is only useful if it can be delivered efficiently. He gives personal testimonials (his wife's shoulder recovered in two days, his elbow tendinitis clears reliably) and says he now recommends the paste on hamstrings before max velocity days as a pre-workout enhancement. The conversation then pivots to cold plunges, where Kula takes a notably strong stance: he considers them counterproductive not just for muscle building (where the bodybuilding world has already pushed back) but for neural performance. [2] — Brian Kula "Cold plunges vasoconstrict blood vessels and suppress the nervous system for up to 24 hours — which means an athlete doing a cold plunge th…" 44:56 Cold suppresses the nervous system for up to 24 hours, meaning an athlete who cold-plunges the Friday before a Saturday meet may have a sluggish CNS during competition. He's not anti-cold-plunge entirely — early in the week is fine — but he banned them as pre-competition recovery at his facility once he understood the neural suppression effect. He connects this to the broader theme of the episode: everything Kula recommends is ultimately about optimizing nervous system function and oxygen delivery, because those two systems determine athletic output.
Hyperbaric chambers push more oxygen into the body but vasoconstrict, limiting blood flow. CO2 paste does the opposite — it vasodilates and uses the Bohr effect to help hemoglobin release oxygen directly into damaged tissue. Kula says the results on athletes have been dramatic enough to call it revolutionary.
