@coming.back.to.he's peptide therapy claims, fact-checked

What did @coming.back.to.he actually say?

Over a 75-day self-experiment, the creator logged a week-by-week side effect diary for red light therapy, covering headaches, fatigue, GI issues, sleep disruption, and an unintended claim that the therapy helped them quit nicotine. They framed it as a community resource, not medical advice, and adjusted their protocol from four sessions per week down to once or twice weekly after feeling, in their words, "like absolute dog shit." That kind of iterative self-correction is actually more honest than most wellness content. The problem is the nicotine claim, which is where the video drifts from anecdote into territory that needs serious pushback.

The creator also attributed early headaches and nausea to dehydration and electrolyte imbalance, and linked bloating and sulfur burps to high-sulfur foods like eggs and red meat, which they then reduced. These are reasonable, if unverified, self-diagnoses.

Does the science back this up?

Some of it, loosely. Red light therapy (photobiomodulation, or PBM) has a real, if early, evidence base. The side effect profile the creator described is consistent with what limited clinical literature reports. But the nicotine cessation claim has essentially no peer-reviewed support specific to red light therapy.

A 2021 review by Hamblin in Photobiomodulation, Photomedicine, and Laser Surgery confirmed that transient headache and fatigue can occur, particularly with high-fluence protocols or when users are dehydrated. The GI complaints are less well-documented in PBM literature and more likely coincidental or related to dietary changes the creator was making simultaneously. A 2019 study by Salehpour et al. in Frontiers in Psychiatry found PBM improved sleep quality in some participants, which makes the week-six sleep disruption the creator reported harder to explain without knowing their exact device parameters, session length, and timing relative to sleep.

The "four times a week" over-use confession is actually consistent with a real concept in PBM research: biphasic dose response, documented by Huang et al. (2009) in Dose-Response. Too much light can inhibit the mitochondrial effects you are trying to trigger.

What did they get wrong (or right)?

The nicotine claim is the biggest red flag. Saying red light therapy "worked so great that it helped me quit nicotine" is an extraordinary claim with no credible mechanistic or clinical backing specific to PBM. There is a small body of research on laser acupuncture and smoking cessation, mostly low-quality, but that is a different modality and a different claim. Attributing nicotine cessation to red light therapy based on 75 days of n=1 experience is not evidence. It is coincidence dressed up as causation.

What they got right: acknowledging the biphasic dose response by cutting back from four sessions to one or two per week shows real, if accidental, scientific literacy. The sulfur burp and bloating explanation, blaming high-sulfur foods rather than the therapy, is probably the correct read. And the general disclaimer framing is appropriate, even if a disclaimer does not neutralize a bad claim.

The over-frequency problem

Using red light therapy every other day, amounting to roughly four sessions weekly, and then feeling worse is a pattern consistent with hormetic overload. The biphasic dose response in PBM is real. More is not better, and the creator figured this out the hard way.

What should you actually know?

Red light therapy is not a fringe pseudoscience, but it is also not a proven treatment for most of the conditions it gets marketed toward. The FDA has cleared specific PBM devices for specific indications, including pain and wound healing, but the wellness optimization claims that dominate TikTok exist in a much grayer space. If you are experiencing side effects like persistent headache, significant sleep disruption, or GI symptoms, stop the protocol and talk to a clinician before resuming. Adjusting your diet to manage burps is not a substitute for understanding why your body is reacting the way it is.

The nicotine cessation claim deserves a specific callout: do not use this video as a reason to try red light therapy as a quit-smoking strategy. Evidence-based options exist, including nicotine replacement therapy and prescription medications, that have been tested in randomized controlled trials. A TikTok anecdote is not a treatment protocol.

Finally, device parameters matter enormously in PBM. Wavelength, power density, session duration, and distance from the device all affect outcomes and risk. The creator never mentions any of these. Two people using "red light therapy" could be having completely different physiological experiences depending on their setup.
