About Doserly

As I got older, I started dealing with some symptoms that led me to TRT, or testosterone replacement therapy. Along the way, I was also taking supplements and medications. Before long, keeping track of everything was harder than I’d expected.

The apps I found usually covered one part of the picture. To track everything, I would need several apps and several subscriptions. Even then, the information would sit in separate places. It was frustrating to have so much to keep track of and no easy way to look at it together.

The questions I wanted to answer were fairly simple. What had I changed? When had I changed it? Was I feeling any better? But with doses, timing, symptoms and lab results all involved, getting a useful answer wasn’t simple at all.

I’m based in Ontario, Canada, and I’ve spent more than 20 years working in IT. So I started building the app I wished I could find.

I wanted one place to record what I was taking, how much, when I took it and how I felt. I wanted to be able to look back over months and see what had changed. And I wanted that history to be useful when I sat down with my doctor.

That’s where Doserly began. I also wanted it to work without an internet connection. Logging a dose or checking my history shouldn’t depend on having a signal.

As those records build up, there can be a lot to look through. The AI-assisted insights and monthly reports help bring possible patterns to my attention. A pattern in my records doesn’t tell me what caused it, but it gives me something to ask my doctor about. That was a big part of what I wanted from the app: a better starting point for those conversations.

While doing my own research, I came across a lot of advice on forums and social media. There was plenty of enthusiasm around peptides, supplements and hormones, but it could be hard to tell what was backed by research and what was someone’s opinion.

I wanted to make that a little easier to sort through. The guides grew out of that same curiosity: what do we actually know about this, and where are there still questions?

I use AI to help with the research and writing, and I review the guides myself. We don’t currently have medical reviewers. I include links to the sources so you can read them too, check the information and bring your own questions to your healthcare practitioner.

Doserly started with something I needed in my own life. If you’ve found it hard to keep track of all of this too, I hope it helps you. And if you have a question or spot something that needs correcting, I’d like to hear from you.
