About Auto-Injector
Our Mission: Making Self-Injection Stress-Free
At Auto-Injector, we believe no one should have to struggle with injection anxiety. Whether you’re managing hormone therapy, fertility treatments, or any other self-injection protocol, you deserve a solution that’s simple, reliable, and pain-free.
We’re dedicated to helping thousands of patients overcome injection hesitancy and take control of their treatment with confidence.
How We Discovered the Auto-Injector
Our journey began not in a boardroom, but at a family dinner table. When we launched Spark Hormone Therapy, we were focused on helping patients optimize their health through hormone replacement. But we quickly discovered that many patients struggled with something we hadn’t anticipated: the injections themselves.
One evening, my stepfather—one of our first TRT patients—mentioned he’d been having trouble with his weekly testosterone injections. The anxiety would build up for days. He’d prepare the syringe, then stand there, unable to go through with it.
Then he told me about a device he’d discovered that changed everything.
Then he told me about a device he’d discovered that changed everything.
I was intrigued. If this device could help him—and potentially hundreds of our other patients—we needed to learn more.

From Personal Discovery to Helping Thousands
From Personal Discovery to Helping Thousands
I ordered one for myself, even though I didn’t have significant injection anxiety. What I discovered surprised me: even without fear, the device made injections dramatically easier and more consistent.
No hesitation. No second-guessing the angle or depth. Just simple, reliable, pain-free injections every single time.
We started recommending it to our hormone therapy patients, and the feedback was overwhelming:
“I can finally do my own injections without my wife’s help.”
“I don’t dread injection day anymore.”
“This device saved my TRT protocol—I was about to quit.”
We realized this wasn’t just helpful for our clinic patients. This could help anyone struggling with self-injections.
An Unexpected Community: IVF & Fertility Patients
As we built Auto-Injector.co, something unexpected happened. We initially focused on testosterone replacement therapy patients—mostly men dealing with weekly injections. But through Reddit communities, YouTube videos, and word-of-mouth, we discovered an entirely different group who desperately needed this solution:
Women undergoing IVF and fertility treatments.
These women face something uniquely challenging: daily progesterone in oil (PIO) injections with large, uncomfortable needles—for months.
The messages started pouring in:
“I’ve been staring at my PIO injection for 45 minutes and can’t do it.”
“Your device saved my IVF cycle. I was ready to give up.”
“I can finally do my injections without crying.”
Today, the majority of our customers are women navigating fertility treatments. Their courage and determination inspire us every day, and we’re honored to be a small part of their journey toward parenthood.
