I have been a diabetic for 33 years, injecting insulin four times a day. This is the worst disease for someone who is needle phobic. So I started using a needle-free injection system from the beginning.

Several years ago the injector I used was discontinued and I had to find a replacement. Happily, I found injecttneedlefree.com and the Comfort-In system. This provides virtually painless injections. It gives accurate and consistent dosing. I feel it is a big part of why I am able to consistently get HbAiC readings of 6.1 or so.

For anyone who is needle-phobic this is the best solution. I have been extremely satisfied with this supplier and the injector. I highly recommend both!


How did I survive without this ?? Being a T1 Diabetic and suffering from extreme needle-phobia I would often skip my medication simply because I didnt want to inject myself. This device takes the pain and anxiety out of insulin-therapy treatment. I find it very easy to set up and use day to day,takes me about 2-3 minutes start to finish. A dramatic difference from the 30 minutes to a hour it would take me each night to fight my anxiety. Extremely well built and designed. A must have product for anyone that has to use needles on a daily basis.


My parents instilled in me the importance of honesty and hard work in my life. These values and principles kept me out of trouble, which led me to a long and successful career as a law enforcement officer. Good health and agility are required in order to safeguard lives and properties, protect the innocent,
prevent crime, and apprehend criminals. Therefore, I regularly exercised several times a week and watched my diet in order to maintain good health. A couple of years shy of retirement, I gained twenty pounds and no longer had the energy to exercise or play sports with my teenage son. I don’t use drugs, smoke, or drink alcoholic beverages, but I drink three or more sodas a day. An annual doctor’s examination, complete with blood work, revealed I have what most middle-aged men have; low testosterone and high blood pressure.

My doctor prescribed testosterone replacement therapy (TRT), blood pressure medication, and ordered me to stop drinking soda. To my disappointment, my insurance company would only cover TRT injections and not creams, which cost about six-hundred dollars a month. Consequently, I was forced to inject 1ml of testosterone with a 25 gauge needle once a week. It took me half an hour to complete my first intramuscular injection as the thought of stabbing myself with a sharp object and self-inflicting pain brought on anxiety and went against my better judgement. I eventually “manned up” and injected the 1 ½ inch long needle into my body, which stung like a bee and left a contusion for two days. I sustained this merciless practice for more than a year. With a few diet changes and TRT, my health improved, but at the same time, I loathed needles. Against my doctor’s advice, I stopped TRT for a few months, until I discovered a needle-free solution with the Comfort-in Jet Injector.

With a new outlook, I resumed my TRT. My doctor prescribed 1ml of testosterone once a week and .5ml of human chorionic gonadotropin (HCG) once a week. I ordered my Comfort-in Jet Injector Kit and upon receiving it, injected the recommended HCG dose subcutaneously, which was painless. In order to stay within my testosterone prescription, I administered two .5ml subcutaneous injections. However, the injections resulted in small lumps with soreness, which took a couple of days to disappear as my body absorbed the oily medication. Subsequently, I decreased my testosterone injections to .25ml each. To my pleasant surprise, they did not result in small lumps or soreness. I’m happy to report that Comfort-in has
enabled me to resume my TRT and HCG treatments without needles or pain, and I don’t have to worry about keeping sharps away from family members or have to maintain and dispose of sharps containers.


To Whom It May Concern
About 18 months ago, I visited my GP as I was having “bedroom” issues, only to find out that I was diabetic; And was explained that this was a common issue with men in general, NOT being able to hold a good hard erection for sexual penetration or intercourse.

My GP put forward a couple of options before me, to starting working on this problem of mine – Erectile dysfunction (ED). The First option was to take oral medication; The Second was Penile Injection Therapy. Injecting my penis was scary thought; I quickly went for the oral medication.

I tried the oral medication for a few months, on and off as I was getting mixed results. I
experimented with different brands and doses, only to be disappointed as the erection (if any) was not on time. And there were side effects, headaches, mood swings etc.

The only option was to go on injection therapy, and I was explained that that once you “know” your dose, the results are excellent. This all sounded good and promising, BUT to put a need in my penis! Not doing this…

I looked for other options and discussed with the GP/Urologist that did not involve putting a needle there. The answer was NO, but I was not convinced, there has to be a less invasive way to administer the medication. I have been avoiding the needle for the past 12 months, and must say that my life was not the same – being a man! So it was time to look at the injection therapy.

So got the TRIMIX, injected a couple of times (with great fear and anxiety) but it was too much for me. Just the thought was enough to run out of the bedroom.

Then I discovered “COMFORT-IN” needle free, I discussed this method with the GP/Urologist, but they were convinced that Injection was the only way.

Being an optimist, I took this into my own hands, purchased “COMFORT-IN” needle free, and studied the device in detail as to how it worked. There are a number of tutorial videos explaining how to use this device… it is simple and it works. The first time I used the “COMFORT-IN” needle free. I got rid of the needles.

As the saying goes: practice makes perfect, with understanding the “COMFORT-IN” needle free & putting it into practice; I have to date have used “COMFORT-IN” needle free with 100% success.

I have got the technique right, and anyone can do this. If only I had discovered “COMFORT-IN” needle free 12 months ago…

With my personal experience with the “COMFORT-IN” needle free, I am looking at setting up a side business selling them in Sydney NSW.

I urge medical professionals to look at “COMFORT-IN” needle free as an alternative to needles… This will put a lot man at ease who have ED, and are not willing to put a needle there.

I have been a vegetarian most of my life. I exercised six or seven days a week; aerobics, weight lifting swimming and running. My children were born while I was in my late 20’s so that was optimal. I have rarely lived in the city. I grew much of my own food. All taken together, I was very fit and took active steps to stay healthy. Imagine my shock when I was diagnosed with diabetes about 12 years ago.

The diabetes was controlled by oral medications for a couple of years, but we knew that insulin was in my future. I am a lifelong needle-phobe so the prospect of using insulin was terrifying and impossible. Several years prior I was a subject at the University of Washington in the Dental Fears Clinic. Three years of weekly treatment and I was able to tolerate getting my teeth cleaned. I was helped, but not a lot by the Clinic.

So my journey to find an alternate to insulin needle injections began. While on vacation, my dear husband spent hours on the internet and found a company in Canada that was manufacturing and selling a needle free system that I used for several years. The company had as their main business the manufacture of precision airplane parts (I am an aircraft engineer) so I had confidence in the injector’s quality. My insurance company was even convinced to pay the costs until they found out that the shipping point was Canada. Only U.S. shipping was allowed. Deep sigh, pay the bill and move on.

Several years in, the Canadian company took a different direction and chose to not make the needle free injector any longer. Back to the internet and that is when I found Comfort-In. Comfort-In is more comfortable to use and I have experienced a serious reduction in bruising and pain as compared to the previous Canadian device. Most injections are barely felt and bruises are rare. This is truly a lifesaving device for me. I really cannot tolerate any needles of any kind. My bloodwork is all done with finger sticks because I have an understanding doctor.


In February of 2014 we took one of our dogs (Benny) to the vet for an exam because he was overweight and very lethargic. Test results showed his blood sugar was 550 and obviously diabetic. At the time he was only 6 years old and the prospect of injecting him with needles for the rest of his life was overwhelming.

Without knowing of any alternatives for needles I did a search and found the Zoe Pet Injector. We made an order but had to wait a few weeks until it arrived. For the time being we had to use needles. Somehow that went ok for the first two weeks but then Benny just didn’t want to cooperate and I was getting stressed.

When the injector arrived we visited the vet again to do a practice injection and determine the right dose. As nervous as Benny usually is he handled the practice injection just fine.

At home, twice daily injections were easy enough although the Zoe injector was not the simplest to use and maintain. Benny cooperated in spite of the loud click of the injector. It took a bit of trial and error to get the dose just right but we did get his blood sugar down to 100-200.

Fast forward to July 2015. One injector has already broken and the company is out of business so I am back on Google searching for a new brand. That is when I found the Comfort-In needle-free injector. We have been using Comfort-in injectors ever since and are so much happier with how it works.

We have learned some tricks over the last three years. Injection location depends on the dog (check with your vet for the best spot). For Benny it is on his back. We inject on the right side of the back for a while and then switch to the left. If the injection site becomes swollen or dry that is the time to switch, otherwise the injection will not be effective. Shaving some hair off also helps.

After all this time Benny and I have settled in to an easy twice-daily routine. After eating he often gets right on to his pillow ready for his injection. Actually he is just getting set for his treats. For a long time we only gave him a treat after the injection but because injectors have at least a faint click that can sometimes startle Benny I distract him by giving him a treat right when I give him the injection. Our other dog, Axel, who we call the supervisor, also gets a treat .

Using the Comfort-in injector is a simple, effective and stress-free process that takes less than a few minutes. I can’t imagine being without one.

This device is a life saver – yes our dog winces, but it’s not from pain – it’s just a reaction, I think for show… and anxiousness to get it over with so he can go back to eating! LOL!

A couple things that I have changed since doing this video (Hadar – I might owe you a new video), I do let my dog eat his whole meal prior to injection now – something I’ve learned from some support groups I follow on facebook. It’s important that insulin and food work together, so it’s safest to be sure they have their whole meal in them before injecting a full dose of insulin. Otherwise, if they don’t finish the rest of the meal, you might have too much insulin on board. I would recommend finding and joining “canine diabetes support and information” group on facebook – AMAZING forum of people that are WELL versed in canine diabetes and are incredibly helpful and supportive. I have literally seen them safe dog’s lives by coaching people through emergencies, there are about 12k members, so someone is always on line to respond and help. And, just a wealth of information. They are huge advocates of testing BG at home, which is something I do not do at this time, but I can see the value in it.

Another change we’ve made, is rather than parting his hair on the side of his chest to inject, I finally took Hadar’s suggestion to go to his lower chest/belly area where he has no hair to potentially interfere with the delivery of insulin. It seems much easier, and doesn’t bother my dog. Not sure if your dog is hairless there, but if so, it can be much easier.

I have always heard that insulin is best injected in the sides of the dog for best delivery and absorption, as I understand it, you’ll want to avoid the scruff of the neck, and always change injection sites to avoid any scar tissue.

I can tell you that I have a gnarly needle phobia, and that transferred to my dog when it was time to inject, our routine got RIDICULOUS, and frustrating, the “wince” you see from my dog in this video is 1,000 times improvement from when I was using a needle! This device was a life saver for both of us! I could NEVER inject with a needle without another person holding my dog and a snarling scene… Now anyone can give the injection with confidence and ease!

Good luck, hope this helps!


Just used the Comfort-in for my 1st insulin injection wasn’t sure what to expect and i had a professional doctor help me go thru the manual just to ease my mind but yes yes yes it’s easy to use i felt like a slight flick when injecting and the sound of the spring startled me sure but zero pain a tiny injection site blood spot easily wiped away. The cover for the insulin vial to transfer it to the syringe was a little scary to apply was worried I’d break the vial but still easy to figure out. All in I’d recommend this product to anyone needing insulin and with needle phobia. delivery was fast too even from Australia to the states.
