Thank you for sharing your EFS story!

Thank you so much Glenn for sharing your EFS Story and Journey.   “I cannot explain how it works but do realize what it has done for me. What I do know is that it stems from Nikolai Tesla’s work with alternating current energy. It is a glass plate with a cord and large light bulb. I hold the bulb to my neck and move it around for 20 minutes. I often tell people, I do not care how it works, I am just glad it does. My wife and children were always afraid and cautioned me at every turn. When we moved last year from …………. (Nov. 2014), I was able to help load and unload three trucks. This is something I hadn’t done in years. “ Read full testimonial emails dated from 2015 and as recently as 2023!

EFS EMG Proof from Dr. Daniel Aviv (Chiropractor)

– Positive Customer Feedback~Thank-you!

Hi Justin & Shannon, Thanks so much for fixing my bulb so quickly. I’m back up and running! I’d like to testify for the record that at 45, my serve (tennis) is harder now than it was when I was in college. Getting back into the sport 10 years ago, I immediately had rotator cuff problems that were common among my peers. They do their exercises, take advil every day and serve softer. I purchased the EFS-100 from you (2002?) and never looked back. No shoulder issues/rotator cuff issues whatsoever. Keep up the great work. Best wishes, Bill Read More…

– Another EFS Letter Comes In

“Some time ago, when I was about 30 something, I landed on my side with my rib cage hitting the top a stripping machine…I went to the doctor the next day, nothing broken but my ribs were bruised on my right side…I was sent home with an elastic brace or wrap for my torso which I used for the next 4 weeks…After the four weeks I still had to be careful, some movements still caused pain. Eventually, I mended…Fast forward about 17 years…I injured my ribs in a similar way. Nothing broken but bruised and sore…This time I had access to an EFS 100…I was able to resume a moderately active lifestyle within the first week and I could barely tell I injured myself midway through the second week…The EFS keeps me active and limber…I am getting older now, 50+, and I am very glad to have a device like this” See rest of the letter Bruce Stewart, Male 50+, staying active and limber Read More…

– Discussion on Energy Science Forum

I have have great success with your machine over the years as you know. I purchased your EFS100 about 10 years ago and have used it for many things, but most noteworthy, to completely eliminate a rotator cuff injury (tennis). I serve harder now at 45 than I did in college without any problems whatsoever. Read More…

– Happy Father’s Day Story

“I wanted to follow up with you on how my father did with his first use of the EFS. As you know, he is 94 and has dementia and has also had a brain bleed…Well, I put him on the EFS for 15 minutes. After about 5 minutes he started just talking about his life… All of a sudden, he just starts talking about so many new things! None of his communication had the distorted flavor of the made up or irrational that his stories have begun to be colored with recently – when he does tell them. Very impressive change in just a few minutes! WOW! Thanks Justin! Feel free to share this success with anyone you wish to.”

– EFS-Fibromyalgia & IBS Story

We want to thank Sherri Wright for her letter and her willingness to share her story with others. From: Sherri Wright Sent: Wednesday, February 23, 2011 7:16 PM To: Justin Brost Subject: TESTIMONIALAfter 6 years of health issues diagnosed as Fibromyalgia, Stress/Depression , High blood pressure & IBS with symptoms that came on suddenly in June 2005 & continued on a daily basis, ranging from mild to extreme – fatigue, body pain in muscles & joints that would wake me up during the night because it was so painful just to move or rollover in bed & keep me bedridden at times for several days, from being able to do just daily chores let alone trying to exercise or do anything that was remotely physical, headaches to full out migraines, nausea( every morning) & have had to be very limited with my diet. Previous to these last 6 years I was active ( skiing, trained for & completed a marathon in Maui, been tandem skydiving, hang-gliding, paragliding. Regular exercise ( running, Bikram Yoga on a daily basis for 6 months then 3 to 4 times a week for 2 years , weights at home & had a membership to the Gym), eating pretty much whatever I wanted & was able to be physical without issue…. I have been using the EFS (Energetic Fitness System) on & off for the last 4 months after being referred by a friend to try this. I have to say I have had tremendous results that the doctors have not been able to even come close to. My energy level has improved, the aches & pains are not keeping me up at night & my recovery time is quicker if I have a bad day. I’m being able to actually eat real meals again & more frequently, my headaches & nausea are becoming less frequent. The more I’m able to use the EFS the better I feel which is why I am getting one so I can use it on a daily basis or as necessary. I recommend the EFS to anybody who wants to improve their energy, speed up recovery & to basically boost their overall health & immune system. I’m able to know what it feels like to have a “GREAT” day again! Friends & Family have been amazed. Thank You –  Shannon & Justin Sincerely, Sherri Wright Daughter, Sister, Wife, Mother of 2 , Stepmom to 2, Friend, Business Owner & Partner : Age 46 “Just a few reasons to be as healthy as can be.” Read More…

– EFS-Fibromyalgia Testimonial #2

From: blakebarrett Sent: Friday, April 15, 2011 8:29 AM To: justin Subject: testimonial About 18 years ago, I was diagnosed with fibromyalgia. As I remember they weren’t even sure it was a medical condition back then. Four years ago I heard about a device that helped in therapy with a variety of medical problems. I stopped by Justin and Shannon’s house to learn more. After talking for a few minutes they offered for me to do a session on the EFS 100. We continued to talk with me learning more about the history of the EFS 100 and the theory of how it works. After 20 minutes, Justin helped me stop, then asked me to stand up and touch my toes, a thought that I hadn’t had in years, I was able to touch the floor! I talked with my wife then purchased one and have used it since. Having a machine at home I try to use it regularly, 2-3 times a week, in the evening while talking with people or watching TV. The living room smells of citrus like after a thunderstorm, a very clean and energized smell. On days that I wake up sore and achy from doing too much the day before, I can do a 20 minute session in the morning and most of the aches and pains go away and I have more energy for the day. The EFS 100 has also showed to help with the uptake of medicine and supplements. I get a quick response to new supplements when I add them to my routine and doctors have tested and monitored the level of some prescriptions I take and have found them to be effective at lower levels. The doctors have also been impressed with how quick my body heals for a 60 year old after the two surgeries I have had since using the EFS. I get nervous thinking of not having access to one.

IDEA World Convention in Las Vegas 2017

EFS wraps up a successful show at IDEA World Convention 2017 in Las Vegas.

– This letter is from a Hard Core athlete

“I have been using the EFS for about 2.5 years now…I went on to buy a machine. I play soccer year round 3-5 times per week as well as snowboard and wakeboard. I play hard. And I injure myself quite often. I have had bad ankles since middle school and I sprain them on a regular basis. With the EFS a sprain that would normally put me out for a month only keeps me out for about 10 days…It wasn’t cheap but it is totally worth it. In 2.5 years it has been extremely reliable with no problems and consistent use. Worth it.” Brent Ahrens, athletic man in mid-twenties & regular EFS user Read More…


I am pushing weight like I did when I was 30 and I feel incredible! I cannot imagine life without EFS – and neither can my clients!

Amateur Athlete – Rob’s EFS Encounter

Rob Lane’s story using EFS My EFS at a Biohacker laboratory offering several powerful modalities such as PEMF (Pulsed Electromagnetic Frequencies) device, NeurOptimal, Infrared sauna and something unique called KAATSU. These all worked powerfully to help aid in my recovery from exercise and injury. My favorite was the PEMF system called EFS.  The lab set me up on many sessions to help me get ready for the biggest event of my career called 24 Hours Of Old Pueblo. It’s a 24-hour mountain bike race that I was invited to be a race partner for my 60th birthday. It doesn’t stop there. I had a lot to do to prepare for this event. I just had a double torn meniscus and bone spur removal surgery on my left knee that was not healing well. I started using the EFS device daily in leading days. I noticed the pain reducing, and swelling, and also noticed amazing amount of energy throughout my entire body. My race partner and I trained together for 60 days leading up to the event and even did an 8 hour race for practice which I used EFS during and was amazing for race performance, pain management and recovery. 5 days leading to the big race I also was recovering from a sprained thumb during training that EFS helped with. During the race I would use EFS between laps to help with neck and knee pain and also for energetic recharge. It was an amazing help getting through those 128 miles over 24 hrs. EFS was the biggest win for me. One last thing to note, the following Monday after the race, we stopped on the way back from Tucson to do a little active recovery ride at this very scenic area. On a narrow trail section I flipped over the handle bars and it slammed my body to the ground so hard I broke my helmet. I had a mild concussion, dislocated both ring fingers, cut my shoulder and injured the rotator cuff and an assortment of cuts and scrapes and was feeling very nauseous. When we got back I got back on EFS for a charging session. This almost eliminated my pain, made the nausea go away and helped my pain levels for the 6-hour drive back home. Read More…
