What are needle-free injections
and how do they work?

Such a great product, which makes a normally uncomfortable experience absolutely pain free. I use it for BPC 157 and it works great. Would highly suggest getting one!

I can’t say enough good things about Comfort-in and their needle-free injector. It has truly been a game changer for Kaiya and me in managing her diabetes. Giving her insulin with traditional needles had become a twice-daily source of stress and anxiety for both of us. She dreaded the injections, and I dreaded putting her through them. Since switching to Comfort-in, that daily struggle is gone—and, most importantly, it has been instrumental in finally getting her diabetes regulated. I can feel confident that she is receiving her full dose of insulin consistently, without the fear and trauma we were experiencing with needles. The injector works beautifully, and the customer service has been just as impressive. They are incredibly knowledgeable about their product and have always been patient, responsive, and more than willing to help. If you have a diabetic dog or cat who struggles with needle injections, I highly recommend Comfort-in. It has made such a difference in Kaiya’s care and in our daily lives, and I’m incredibly grateful we found it.

An absolute game changer for me. I've always struggled with needles and this has opened up so many possibilities. I can't recommend them highly enough!

Comfort-In Literally Saved My Little Dog’s Life I have a small Yorkshire Terrier named LB who was diagnosed with diabetes about two months ago. She had been losing weight, and then one morning I realized she suddenly couldn’t see properly. I immediately took her to the veterinarian, where she was diagnosed with diabetes and severe cataracts that seemed to have developed almost overnight. After spending a couple of days at the vet, LB came home on a special diet and a regimen requiring insulin injections twice every day. That’s when our nightmare began. I live alone, so I had no one to help hold her while I gave the injections. Trying to hold a tiny, frightened dog, tent her skin, and properly insert a needle was extraordinarily difficult. She would yelp and desperately fight me, and I dreaded every injection almost as much as she did. After four or five miserable days, I was becoming desperate. I started searching online for another way to administer insulin and discovered Comfort-In, an Australian company offering a needle-free injection system. Their system uses a specially designed injector and cocking device to deliver insulin through the skin without a conventional needle. It represented a significant investment once I included the injector, cocking assembly, and necessary supplies, but I felt I had to try it. The alternative was becoming unthinkable. I honestly did not know how I could continue caring for LB if every insulin injection was going to be such a traumatic experience for both of us. When my Comfort-In system arrived, I initially had some difficulty using it correctly because I had misunderstood parts of the instructions. I contacted the company for help—and this is where my experience became truly remarkable. It was a weekend, yet within hours I received a call from the owner of the company, who happened to be in Europe attending a meeting. He took the time to FaceTime with me, watch what I was doing, explain what I had misunderstood, and teach me the proper technique for safely using the system with LB. He even brought an associate in Australia into the process to help resolve some of the details. The level of personal attention and concern was extraordinary. Today, LB’s twice-daily insulin treatments are almost unbelievably easy. After she eats, I prepare the insulin, cock the injector, place it against her skin, and press the button. That’s it. She may occasionally give a little yelp, but there is simply no comparison with what we went through using conventional needles. In fact, LB now comes to me after dinner knowing that it is time for her insulin. She is no longer frightened of the process. Comfort-In literally changed our lives and, in my view, saved LB’s life. It turned something that had become nearly impossible for one person and a frightened little dog into a simple routine we can comfortably manage twice every day. I cannot say enough about the technology, the product, the company, or the extraordinary personal support I received from its owner and staff. If you have a diabetic pet requiring regular insulin injections and are struggling with conventional needles, I strongly encourage you to learn about Comfort-In and discuss whether a needle-free system may be appropriate for your pet with your veterinarian. For those already using Comfort-In, I suspect many of you understand exactly why I feel so strongly about it. For those hearing about it for the first time, I hope LB’s story gives you a reason to investigate it. I am enormously grateful to Comfort-In for helping me continue caring for my little dog and giving us back a normal life together. If anyone considering the system would like to hear more about my personal experience with LB, I would be happy to answer questions.

My dog, Wolly the Jackapoo was diagnosed with diabetes after pancreatitis in June last year. After about six weeks he refused the insulin injections. It became impossible to administer his twice shots. It was causing a lot of anxiety for me. A couple a times I had to take him to the vet for help, some times he was getting his insulin late. I stumbled across Comfort-In needle-free injections doing a Google search and thankfully Hadar was able to meet me with a kit here in Melbourne. I have never looked back. It is so easy to use and there is no more anxiety for either of us. It is painless for him and he waits patiently for his shot followed by a treat. It's been a year now and my boy is going great. Thank you Hadar.

Deadset amazing, no needle anxiety, currently using it for testosterone which is super thick, minimum amount of pain and way less tedious then a needle... I can't recommend this enough, also a very helpful team, fast delivery, my location is newcastle and got the kit within a couple days. Ben Major

The needle free device saved our little dogs life! After being diagnosed with diabetes last summer our little dog could not tolerate the twice daily insulin injections. He is usually a cuddly little boy, but was so scared of the needles that he became aggressive and snappy. It was impossible to administer his medication. As a result he had no appetite, and lost a lot of weight and hair. It got to the point that unless we could stabilise his blood sugar he would have to be PTS. After researching needle free injection systems we found Comfort-In, and despite our Vets initial cynicism we decided to purchase it and have never looked back. A year later our little boy is healthy and happy. His blood sugars are stable, he has gained weight, and his hair is regrowing. He tolerates the needle free system very well, and even sits down before we ask him to when it is time to have his meds. Our vet has also become a big fan of the system and now recommends it to others who are struggling with daily injections.
