"I was kind of winging it with my protocol and it stressed me out. Not sure if I was dosing right, forgetting when I last injected, no clear picture of results. Two weeks with Regimen and I feel way more in control. I know exactly where I am in my protocol, when my next dose is, and I'm actually seeing patterns in my data. Huge relief."

"Started TRT a little while ago and was just writing stuff down in notes. This app actually keeps me organized. The reconstitution calculator and dose calculator tell me exactly how much to inject, reminders hit at the right time, and I can track my testosterone levels and how I'm feeling alongside my injection log."

"Brooo, no lie about being better than Shotsy. I did the trial run with Shotsy and the UI just wasn't hitting right like Regimen. Regimen is 'simple' but obviously complex in its information."

"Started Zepbound a few months ago and needed something to track my doses and weight. Reminders keep me on schedule, I can log my injections and see my progress all in one place. The progress photos feature is really motivating too."

"Tried a bunch of other apps and deleted all of them. This is the only one that actually works how I need it to. Love how easy it is to track multiple compounds and the calculator feature is incredible. Developer updates it regularly which is huge."

"I take, cycle, and track numerous peptides. I had been tracking everything via a calendar, notes, and other apps on my phone. It was a pain switching back and forth between apps. Regimen has taken away all of those headaches."

"Great TRT+ tracker with a great team behind it. I reached out to the developers with a question and they immediately got back to me and were very helpful. They actually seemed like they cared about user experience. Highly recommend!"
