Biohackers Rely on Personal Effects Where Device Evidence Is Thin

Chris Williamson asked for the interventions people keep using even when they cannot point to supporting data. The BioCharger became the group’s clearest example: a device that participants described in elaborate technical terms while conceding that they did not know whether it works.

As described in the discussion, it combines red light, pulsed electromagnetic fields, radio frequencies, a Tesla coil, and 12 noble gases in tubes. It offers roughly 100 programmed settings, or “recipes,” including options labeled for parasites, insomnia, and constipation. One participant put the evidence problem plainly: “there’s zero clinical data.”

That did not settle the question for the people who reported an effect. A participant who received a BioCharger after saving a patient’s life said the patient had credited it with improved sex drive; the participant’s husband also said he could feel something from it. Another participant said the “raisin bran” setting had reliably relieved constipation after travel: sit in front of it for about 12 minutes, they said, and the result is immediate.

Williamson’s experience ran in the other direction. Tony Robbins lent him a unit for about a month—Robbins, Williamson said, has one in every room of his house—and Williamson used it “consistently, semi-consistently.” He noticed no difference. What he did notice was that placing a phone near the device made it glitch, as did Bluetooth equipment.

The WINBACK machine occupied a similarly uncertain category. A participant had been using the high-radio-frequency device, described as TECAR therapy, on a hamstring. It uses patches and a controller that produces electrical signals, but the user distinguished it from electrical muscle stimulation and said they had not found good U.S. data. Still, they felt better and described a peculiar feature: the sensation seemed to localize where the pain was.

The useful distinction in both cases was not between a device that “works” and one that does not. It was between a repeatable personal response and a clear account of what produces it. For some users, the former was enough to justify continued experimentation.

The roXiva system was presented less as a treatment for a specific injury or symptom than as a way to induce a powerful altered state. It combines a vibrating lounge, headphones, and a flickering lamp, with sessions ranging from five to 60 minutes. A participant described its proposed basis as light-and-sound entrainment: using coordinated light and sound to shift brain-wave states.

In practice, the participant said, the combination can feel like a psychedelic experience without ingesting a substance. The system pairs the lounge’s vibration with headphones and light delivered through the lamp. One 45-minute session, called “Rebirth,” uses sounds described as womb noise and fetal heartbeats. The participant said users may drift between sleep and wakefulness before the final minutes intensify: the music crescendos, the lights brighten, the heartbeat-like rhythm accelerates, and the session ends in darkness after an adrenaline-like surge.

Williamson compared the lounge to the Shiftwave chair he keeps at home, though he said roXiva was more comprehensive. Shiftwave, he said, does not merely vibrate; it “fucking shakes.” Another participant said that powerful vibration could serve as a distraction during breathwork, allowing breath holds to extend by about 25%. They also said users wear a fingertip monitor during sessions and that heart-rate variability rises sharply.

The womb sounds prompted Williamson to connect the roXiva session with Stephen Porges’s Safe and Sound Protocol. Williamson described that protocol as a form of nervous-system re-entrainment involving facilitated work, meditation, breathwork, and sound. Porges had told him, Williamson said, that the soft, reassuring vocal sounds mothers make to their children sit in the frequency range used by the protocol. Williamson added that mothers and young in humans, dogs, and horses share a similar vocal band, which he said helps explain the ease of connection between humans and those animals.

Hyperbaric oxygen therapy was discussed as a more familiar intervention, but Williamson’s case for it remained primarily experiential. He uses a hard-shell chamber at 2.2 ATA and described a 90-minute protocol: 20 minutes of 100% oxygen through a mask, five minutes of normal oxygen, then repeated intervals at depth.

Another participant described becoming profoundly relaxed in a session at Brigham Buhler’s facility, attributing part of the effect to the chamber’s sensory-depriving character. The group characterized the chamber itself as standard equipment used in operations for a long time, rather than a newly invented biohacking device.

Hydrogen led to a more technical comparison because it can be delivered through water bottles, tablets, baths, and inhalation. One participant used a test kit on a hydrogen bottle and tablets. The bottle, they said, produced roughly 8 to 10 ppm, more than the tablet, but tended to fail after around 300 uses. Inhalation was described as the method that can introduce the highest concentration into the body. Research on transdermal absorption in a hydrogen bath, by contrast, was said to be limited.

The group also identified the obvious problem in judging a hydrogen bath: a hot tub is relaxing whether or not hydrogen has been added. One participant said the relevant trial would keep bathers unaware of whether their water contained hydrogen.

The proposed mechanism was that hydrogen acts as a selective antioxidant, able to accept or donate electrons. Participants said this could reduce inflammation and soreness without suppressing the adaptive response to exercise, unlike what they described as high-dose synthetic vitamin C, vitamin E, or nonsteroidal anti-inflammatory drugs.

That claim led into cold exposure. One participant argued that concern over post-workout cold plunges blunting muscle-building adaptation had been overstated. In their account, muscle temperature must drop by about one degree Celsius, which requires at least 10 minutes in sufficiently cold water; the research concern therefore applies to longer plunges, not a brief cold shower or three-minute dip. Their practical advice was to wait several hours after training before doing a long plunge.
