Anyone want to discuss PEMF (Pulsed Electromagnetic Field) therapy?
I have been doing various daily PEMF treatments with homemade devices for the last 6 months, and have been really pleasantly surprised with the results.
Mainly used the PEMF treatments for early onset dementia symptoms, so I was interested in brainwave entrainment, reducing inflammation, and increasing circulation. The results have been very positive with improvements in short term and long term memory, processing, word finding, fatigue, and just how my head/brain feels. I know these are all subjective measurements/results, but the results have been too dramatic for me to ignore and shrug it off as just placebo. I also discovered that PEMF is very helpful to reduce/eliminate bodily aches and pains, ED (yep!), BHP symptoms, and getting to sleep.
Not sure how the technology interacts with the human body to bring about such positive results, but somehow it helps cells to improve circulation, reduce inflation, and signals the cells to act. Just a few milli Tesla within a window of frequencies is all that is needed, and this is easy to generate with a homemade device.
Commercial PEMF devices are quite expensive ($1,000s). Fortunately it’s not difficult or expensive to make an effective device yourself. For about $75-$100 you can make an effective PEMF device if you are not afraid to learn how to do basic soldering, simple electric circuit wiring, and some simple DIY skills like turning coils of magnet wire and wrapping electrical tape around them.
Lot’s of good research for PEMF over the last 30 years, it’s proven to be safe and versatile method of treatment, and noninvasive.
As alpha has mentioned, we’ve had some discussions on this in the past. Just go to the Search button in the top right corner of the screen and search on PEMF, or just click on this search link: Search results for 'PEMF' - Rapamycin Longevity News
He has a youtube channel, search for PEMF by Steeve. There are plans on the Patreon there to make a basic 4” 100 Turn coil that generates 10 Gauss and uses 10 Watts very cheaply, there are videos that show how to make the coils and do the wiring, etc. This setup can provide effective PEMF home treatments to various parts of the body, and is in alignment with the Bob Dennis devices. On Bob’s Micropulse site he lists the frequency sequences for his devices, and all can be duplicated at home. The Steeve site isn’t organized very well but if you are persistent it’s all there, including wiring diagrams. I have made coils from 2” to 8” that generate from 10G to 50G, bipolar, 1HZ to 150KHz, for various therapies I am trying to achieve. Check out the site, I would be happy to answer any questions.
Bob Dennis is probably the most authoritative person today on PEMF therapy. You won’t be able to duplicate his devices 100% but close. The features of his devices include:
-unipolar and bipolar signals
-superimposed signals
-adjustable frequency
-adjustable magnetic field strength
-adjustable time
-frequency/signal sequences
You can duplicate all of these features at home but not in exactly the same way BD does with his products.
Steeve has plans to make a full body mat if that is what you were interested in. Right now I am making a “torso” mat that lays against the backrest of a couch so I can get treatment from neck line down to waiste line while sitting on the couch watching tv Lol
I don’t have personal experienced with PEMF devices, but can say that the literature is all over the place with respect to the differences in devices and protocols used and that’s a huge problem because there are so many parameters that influence the effect on cells. Comparing different studies is usually like comparing apples to oranges.
My PEMF full body bio mat was delivered today. It’s Luxuryade A9000 PEMF Red Light Therapy Photon Body Massage Jade Tourmaline Heating Bio Mat Health Care Amethyst Mattress. Bought it on Alibaba.com. Have no idea yet what to do with it and the best time to use. Cannot even decide where to put - on floor or bed. Any advice is appreciated.
In the 80’s I made an ELF Gauss meter, basically a super het receiver tuned to 20hz to 100hz as there was a lot of hullabaloo about ELF (extra low frequencies) causing cancer.
ELF is what is in your walls, 60hz in NA and 50hz in other parts of the world. ELF penetrates well but drops rapidly in intensity as the distance increases. If you have a “hot spot” like the electrical service entrance to your home or appt, you can avoid the “risk” by staying about 2 ft away. Power lines are another matter due to the high current and voltage.
I have one interesting story about a survey I did of a friends home, for another time.
I find PEMF is an interesting tech and there appears to be some interesting studies on it. There are so many variable with a piece of gear like this to sort out but there is also a lot of easy science involved in making one. as has been noted by @RufusDawes
I did quick Perplexity search. I stopped at getting it to layout a circuit but it seems like it was ready to do that as a follow up prompt!! Amazing!
There is some good info on how to use this tech and potential results.
Have a huge disappointment with my PEMF mat from China. Cheap products from China shouldn’t be trusted! I tested 850 nm LEDs (invisible light) and they are not functional, don’t have IR glow. The manufacturer immediately offered to refund after I presented proof - was surprised how easy it was, which is another red flag - they know that their 850 nm LEDs are either not wired or are dummies. Most ppl probably don’t even test (assuming that if 660 nm LEDs work then 850 nm should work as well).
That’s an excellent approach, most people don’t know how easy it is to do this test.
I keep a couple UV test cards handy to keep track of the performance of the UV sterilizer we use to keep our tools and empty vials sterile. We also have overhead UV C lights on timers in the lab and a UV / HEPA air sterilizer running 24-7.
Thanks for sharing your experience it’s great to hear you’ve noticed improvements. That said, the evidence for PEMF in areas like dementia, ED, and BPH is still limited, so it’s hard to know how much is due to the treatment itself.
I’d also be a bit cautious with DIY devices since they haven’t been independently tested for safety or effectiveness.
The 10-Minute Biohack That Recharges Your Mitochondria | Dr Alfredo Franco-ObregĂłn
I. Executive Summary
The core thesis presented by Dr. Alfredo Franco-ObregĂłn dictates that skeletal muscle serves as a primary homeostatic and endocrine regulator of the human organism, and its metabolic machinery can be non-invasively modulated via specific, low-energy pulsed electromagnetic fields (PEMFs). This paradigm, termed magnetic mitohormesis, operates on the principle that terrestrial biology evolved within an ambient geomagnetic field, rendering fundamental biochemical processes sensitive to electromagnetic flux. At the molecular scale, flavin adenine dinucleotide (FAD) inside cryptochrome proteins (specifically CRY2) acts as a magnetic antenna due to the resonant ring structure of nitrogen isotopes possessing distinct magnetic moments. Photoactivation of FAD enables a direct macromolecular interaction between CRY2 and Transient Receptor Potential Canonical 1 (TRPC1) calcium channels on the plasma membrane.
When stimulated with a precise electromagnetic wave architecture—characterized by an amplitude of 1.0 to 1.5 millitesla (mT), a pulse frequency of 15 to 50 hertz (Hz), and an ultra-fast rise time (gradient)—the CRY2-TRPC1 axis triggers a controlled influx of cytosolic calcium. The mitochondria rapidly buffer this calcium, stimulating oxidative phosphorylation, upregulating peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α), and generating low-level reactive oxygen species (ROS). This brief, non-destructive mitohormetic stress mirrors the downstream signaling cascades of aerobic exercise without inducing mechanical microtrauma or consuming a substantial adenosine triphosphate (ATP) budget for structural cellular repair. Consequently, the spared ATP is dedicated to synthesizing and releasing a systemic secretome composed of myokines, metabolites, and extracellular vesicles.
Clinical and preclinical data demonstrate that this localized muscular activation (e.g., of the lower limb using a uniform solenoid coil) induces profound systemic cross-talk. Phenotypic shifts include the browning of adipose tissue via adiponectin signaling, the mitigation of contralateral muscle atrophy during immobilization, and long-term preservation of knee extension strength. Furthermore, emerging evidence highlights systemic immunomodulatory and antioncogenic properties: PEMF-conditioned serum downregulates the epithelial-to-mesenchymal transition (EMT) in malignant cells and reprograms tumor-associated macrophages toward an antitumoral M1 phenotype via a TRPC1-STING inflammatory axis. This translational framework has culminated in regulatory clearances (including FDA and NMPA) targeting sarcopenia and age-related physical frailty.
II. Insight Bullets
Terrestrial Geomagnetic Baseline: Cellular biochemistry is evolutionarily calibrated to the baseline magnetic field of the Earth, serving as a foundational environmental setpoint for structural development and metabolic modulation.
Magnetic Mitohormesis: Low-energy electromagnetic fields act as a sub-lethal adaptive stressor (mitohormesis), forcing mitochondrial upregulation, replication, and clearance of metabolic debris without inducing cellular apoptosis.
Flavin Adenine Dinucleotide (FAD) Antennae: The molecular architecture of FAD features a delocalized electron network and nitrogen resonant rings that function as an organic magnetic antenna capable of sensing weak external field variations.
Isotopic Magnetic Moments: Nitrogen isotopes within the flavin ring possess an intrinsic magnetic moment, representing one of the few organic isotopic elements capable of direct physical alignment and transduction of magnetic forces.
Epigenetic Arrest via Magnetic Deprivation: Shielding muscle cells completely from ambient magnetic fields stalls development at both the genetic and epigenetic levels, highlighting an absolute biological requirement for magnetic inputs [Yap et al., 2019](https://pmc.ncbi.nlm.nih.gov/articles/PMC6902701/).
TRPC1 Gating Mechanosensitivity: Transient Receptor Potential Canonical 1 (TRPC1) functions as a transmembrane sensory integrator, translating both mechanical forces and magnetic stimuli into intracellular calcium cascades.
Cryptochrome-TRPC1 Macromolecular Coupling: Cryptochromes (specifically CRY2) physically interact and co-translocate with TRPC1 channels following magnetic stimulation, forming a synchronized magnetotransduction complex [MitoCharge Research, 2024](https://pmc.ncbi.nlm.nih.gov/articles/PMC11817702/).
Photomagnetic Transduction Interdependencies: The cryptochrome-mediated response leverages photoactivation (via blue-light frequencies or endogenous biophotons) to prime the complex, allowing subsequent magnetic alignment to modulate channel opening.
Mitochondrial Adaptation Over Cellular Adaptation: The primary entity executing cellular adaptation is the mitochondrion; structural changes within the host cell are secondary consequences of shifted mitochondrial respiration and gene expression.
Intracellular Calcium Buffering: TRPC1 activation drives cytosolic calcium influx, which the mitochondria rapidly buffer to stimulate downstream dehydrogenase activity and augment oxidative phosphorylation capacity.
Skeletal Muscle Endocrine Capacity: Skeletal muscle functions as the body’s largest endocrine organ, constituting roughly 40% of total body mass and operating as a systemic metabolic feeding center for distant tissue networks.
The Muscular Secretome: Muscle activation prompts the synthesis and systemic release of myokines, extracellular vesicles, and metabolites that enter the bloodstream to execute systemic homeostatic adaptations.
Organ System Cross-Talk: The myokines released from stimulated muscle tissue participate in bidirectional paracrine and endocrine cross-talk with the brain, bones, liver, kidneys, and adipose tissue.
Muscle-Fat Cross-Talk and Beiging: Muscle-derived secretome components interact with adipose tissue to downregulate chronic inflammation, promote the browning (beiging) of white fat, and increase adiponectin secretion.
Innate Biophysical Forces: Human development is constantly governed by two immutable biophysical forces: the Earth’s gravitational field and its geomagnetic field, both of which serve as continuous evolutionary constraints.
Exercise as Gravitational Interaction: Physical resistance training and aerobic exercise are fundamentally interactions with gravity, where skeletal scaffolds isolate mechanical load to force mitochondrial structural compliance.
Spaceflight-Induced Degeneration: In microgravity and magnetoshielded exo-atmospheric environments, the absence of baseline biophysical forces causes rapid, accelerating muscular atrophy and severe systemic metabolic dysfunction.
Synonymous Transcriptional Cascades: Mechanical loading and precise PEMF exposure utilize identical downstream transcriptional co-activators, notably PGC-1α and NRF2, to drive mitochondrial biogenesis.
Endogenous Biophoton Emission: Cellular metabolic processes involve discrete electron orbital transitions that emit non-visible biophotons, potentially providing the localized electromagnetic priming needed for internal cryptochrome activation.
Transmembrane Force Integration: Subunit heteromerization (such as TRPC1 compounding with TRPC3) allows a single channel complex to independently integrate disparate biophysical modalities, including mechanical stretch and magnetic flux.
Extreme Low-Frequency Specificity: Biological efficacy is restricted to the extremely low-frequency (ELF) range (kilohertz carrier bursts modulated down to double-digit hertz), preventing the ionizing or thermal damage seen at higher frequencies.
Narrow Amplitude Window: The therapeutic index of magnetic mitohormesis peaks sharply between 1.0 and 1.5 millitesla (mT); deviations below or above this threshold result in a significant drop-off or cessation of biological activity.
Pulse Frequency Constraints: Barrages of electromagnetic spikes must be delivered within a tight 15 to 50 Hz frequency band to properly resonance-match the kinetic requirements of the biological target molecules.
Criticality of the Waveform Gradient: The rise and fall time (slew rate) of the electromagnetic wave must be nearly instantaneous to maximize the time the molecule spends at peak amplitude (1.0–1.5 mT) and zero, preventing sub-optimal intermediate states.
Structural Anisotropy of Targets: Because FAD antennae possess structural anisotropy (directional asymmetry), the orientation of the applied magnetic field relative to the tissue coordinates directly impacts the magnitude of the signal transduction.
Evolutionary Heritage of TRP Channels: TRP channels originated evolutionarily as primitive visual and photo-transduction units in organisms like Drosophila, explaining their conserved modern sensitivity to photomagnetic stimuli.
The 10-Minute Mitohormetic Ceiling: In vitro and in vivo models confirm that a 10-minute exposure represents the physiological ceiling for positive adaptation; extending duration towards 40 minutes introduces unnecessary oxidative stress and drops efficacy.
Localized Stimulation with Systemic Reach: Enclosing a single limb within a uniform solenoid coil restricts direct exposure to a clean muscle block (minimizing visceral tissue variables) while distributing therapeutic benefits systemically via the bloodstream.
Contralateral Muscle Sparing: Stimulating one limb induces a systemic endocrine response that significantly mitigates muscular atrophy in the contralateral, unexposed, or immobilized limb.
Long-Term Functional Preservation: Clinical trials in patients undergoing ACL reconstruction or suffering from osteoarthritis demonstrate that brief PEMF interventions preserve quadriceps extension strength for up to six months post-therapy.
Aerobic Profiling Concordance: The phenotypic adaptations induced by specific PEMF parameters strictly parallel aerobic endurance training (increased capillarization, fatigue resistance, and dark muscle coloration) rather than hypertrophic bodybuilding.
Absence of Structural Microtrauma: Unlike physical exercise, magnetic mitohormesis stimulates downstream aerobic signaling pathways without causing mechanical tearing, sarcolemmal damage, or inflammatory structural microtrauma.
Optimized Metabolic Budgeting: Because PEMF requires no mechanical movement, the cell expends no ATP on structural kinetic work or contractile repair, allowing the entire metabolic budget to be directed toward secretome synthesis.
Intramyocellular Fatty Acid Shift: PEMF-stimulated muscle demonstrates a heightened reliance on lipid oxidation, increasing the vesicular packaging of internal intramyocellular fatty acids to cleanly fuel adapted mitochondria.
Microbiome-Mediated Bone Preservation: Fecal microbiota transplantation (FMT) from magnetically stimulated donor mice to unexposed recipient mice increases bone mineral density, indicating a secondary systemic pathway regulated by the gut microbiome [Tai et al., 2020](https://doi.org/10.1096/fj.202000285R).
Fetal Bovine Serum (FBS) Substitution: The secretome harvested from brief, magnetically programmed muscle cells stimulates in vitro cellular proliferation at a velocity equal to standard fetal bovine serum, offering a sustainable alternative for biotech manufacturing.
Oncological Migration Suppression: Serum harvested from human subjects following localized PEMF therapy exhibits the capacity to suppress the proliferation, invasion, and migration of aggressive breast cancer cell lines in vitro [NUS Breast Cancer Study, 2025](https://www.straitstimes.com/singapore/magnetic-pulses-boost-breast-cancer-chemo-potentially-reducing-side-effects-nus-study).
Macrophage Reprogramming via TRPC1-STING: Specific PEMF configurations polarize tumor-associated macrophages from a pro-tumor M2 phenotype to an antitumoral M1 phenotype via a TRPC1-STING-dependent NF-ÎşB inflammatory axis [QuantumTX Cancer Study, 2024](https://www.researchgate.net/publication/405946007_Magnetic_Reprogramming_of_Macrophages_Stimulates_Phagocytosis_of_Breast_Cancer_Cells_via_a_TRPC1-STING_Inflammatory_Axis).
Chemotherapeutic Sensitization: PEMF exposure physically opens the TRPC1 gateway in malignant cells, accelerating the intracellular accumulation of agents like doxorubicin, thereby reducing the required systemic chemotherapeutic dose by half [NUS Breast Cancer Study, 2025](https://www.straitstimes.com/singapore/magnetic-pulses-boost-breast-cancer-chemo-potentially-reducing-side-effects-nus-study).
Regulatory Integration for Sarcopenia: The translation of this specific magnetic paradigm has achieved medical device clearance from global regulatory bodies (including the US FDA, China’s NMPA, and Singapore’s HSA) designated explicitly for the treatment of sarcopenia and muscle wasting.
IV. Actionable Protocol (Prioritized)
High Confidence Tier (Level A/B Evidence & Regulatory Clearance)
Target Condition: Clinical sarcopenia, muscle wasting, post-surgical immobilization (e.g., repairing ACL injuries, hip replacements), and osteoarthritis rehabilitation.
Device Architecture: Utilization of an FDA-cleared, NMPA-approved uniform solenoid coil system (e.g., QuantumTX MitoCharge/BIXEPS platform). Flat mats, flexible sheets, or uncalibrated induction coils do not maintain the required uniform field geometry across target tissues.
Dosing Parameters: 10 minutes per session, administered twice per week for a minimum duration of two months to establish a persistent metabolic baseline.
Anatomical Targeting: Enclosure of a clean skeletal muscle block (primarily the lower limb/calf and thigh) within the center of the solenoid core. This concentrates the magnetic flux within highly responsive oxidative muscle tissue while minimizing extraneous visceral organ exposure.
Contralateral Alternation: Alternation of the exposed limb across successive sessions. Clinical data confirms that unilateral stimulation triggers a systemic endocrine secretome capable of cross-feeding and preserving mass in the unexposed contralateral limb.
Experimental Tier (Level C/D Evidence - High Safety Margins)
Biotech Tissue Engineering & Cell Culture: Application of 1.0–1.5 mT, 15–50 Hz pulsed electromagnetic fields to skeletal muscle or mesenchymal stem cell lines for exactly 10 minutes to harvest high-potency, growth-factor-dense secretomes, substituting for animal-derived serum (FBS) in bioprocesses [Yap et al., 2019](https://pmc.ncbi.nlm.nih.gov/articles/PMC6902701/).
Adjunctive Oncological Sensitization: Localized 30-minute PEMF application targeting malignant lesions immediately prior to low-dose anthracycline chemotherapy (e.g., doxorubicin) to enhance tumor cell permeability via TRPC1 gating. Note: Early-phase clinical validation is underway; oncological applications must remain strictly supervised under investigational clinical trials [NUS Breast Cancer Study, 2025](https://www.straitstimes.com/singapore/magnetic-pulses-boost-breast-cancer-chemo-potentially-reducing-side-effects-nus-study).
Systemic Secretome Induction: Utilizing localized lower-limb stimulation to prompt systemic anti-inflammatory, antitumoral, and lipolytic adaptations via myokine cross-talk.
Red Flag Zone (Claims Debunked or Safety Data Absent)
Chronic Over-Exposure (>40 Minutes): Extending exposure durations beyond the validated 10-minute hormetic sweet spot (e.g., 40+ minutes) eliminates therapeutic benefits and risks inducing excessive intracellular reactive oxygen species (ROS) accumulation and mitochondrial distress.
Uncalibrated Consumer PEMF Mats: Commercial consumer magnetic mats making generalized longevity or “exercise replacement” claims without displaying verifiable wave architecture parameters (specifically rapid gradient rise-times, 1.0–1.5 mT amplitude windows, and 15–50 Hz pulse rates) are classified as Safety Data Absentand lacking clinical efficacy.
Complete Magnetic Shielding: Occupational or experimental environments that completely isolate the human organism from ambient geomagnetic forces provoke rapid epigenetic down-regulation and muscle-maintenance failure [Yap et al., 2019](https://pmc.ncbi.nlm.nih.gov/articles/PMC6902701/).
March 2025 Antioncogenic Rest-State Secretome Study: The specific manuscript detailing the sustained constitutive release of cancer-starving myokines in human female serum one month after completing a 4-week PEMF protocol remains Source unverified in live search on major clinical databases. Do not rely on this specific long-term cessation claim as a standalone clinical oncology intervention.
