AI Slop - don’t waste your money

Very buggy almost unusable. Design of the app is laughably ugly and you can tell the developer just got AI to built the whole thing.

Plus there’s a hard paywall with no free trial. Can’t believe I wasted 20 minutes just to be expected to pay $100 upfront to even try it out…

Don’t recommend.

(P.S: I use the app Milligram it’s a much better alternative to tracking your peptides)

Response from developer

Clearly one of our competitors is feeling the pressure, using a review to promote their own app. For the record: Regimen has a free plan for one compound, a 14-day free trial, and nothing is paid upfront. Users praise Regimen for its design and ease of use, so read the reviews and judge for yourself.

Incredibly Simplified!

Whoever created and designed this app deserves huge kudos. Been using this for almost 6 months. It’s an amazing tool that makes tracking and organizing your peptides and other injectables super simple and efficient!! 100% worth the cost although I wish it was a lifetime subscription for the fee or a one time payment. My ONLY complaint about this app so far is that the Tesamoreline/Ipamoreline blend is not available as an option and have to do the two separately which messes up the dosing so you gotta manually adjust accordingly. Hopefully they add that really soon. Keep up the awesome work and hopefully y’all see the review and recommendation!

Response from developer

The design work is something we put as much weight on as the function. Glad you noticed. That blend is in the latest update. Glad to have you with us.

Excellent App! And Updating!

Tried several different apps to log my protocols. Regimen has everything that I was looking for! Calculators to dial in the maths, check off type of dose logging to make daily injections easy, as well as Health integration and blood test integration. The best part is they listen to the community and keep improving an already great app! Excited for the future.

Need to pay

Was using website to reconstitute nasal peps no problem but thought I’d o downloaded App would be easier 🤦‍♀️ have to create account and pay - no thanks!

Response from developer

Thanks for trying the app. Regimen has a free plan that includes the calculators, so there's nothing to pay. If the paywall screen appears, just close it to continue on the free plan.

Gold standard!!!

Finally an app that gets protocol management right.

I’ve tried multiple apps for tracking TRT, peptide, and bioregulator protocols but this is the first one that actually fits how a real regimen works. (Nod to app name!)
Dosing and scheduling: Multiple compound status (daily, EOD, weekly) with reminders that hit at the right times, not one generic daily alert.

Inventory tracking: Always know how many days of a compound are left - so I don’t run out mid cycle.

Conversion calculator: the best part. mg/mcg conversions, IU draws based on concentration, and reconstitution math. All built-in, no more manual calculations.

The missing piece between "protocol in my head" and actually managing it properly. Recommend it for anyone regardless of level. Peace of mind and money well spent.

FAQ

What does Regimen do?

Regimen helps you manage peptide protocols, TRT, and GLP-1 medications with precision. You can track multiple compounds simultaneously, each with its own schedule, dosing, and cycle. The app also includes a built-in reconstitution calculator and allows for custom scheduling of doses.

What types of medications can I track?

You can track a wide variety of compounds including peptides (like BPC-157, TB-500), GLP-1 medications (Semaglutide, Tirzepatide), Testosterone Replacement Therapy (TRT), Hormone Replacement Therapy (HRT), performance compounds, oral medications, nasal sprays, and custom medications not found in the database.

How much does Regimen cost?

The app offers a free tier to track one compound with no limitations. Premium features, including unlimited compounds and advanced integrations, are available via a subscription of $4.99/month or $39.99/year, with a 14-day free trial.

What are the benefits of integrating with Apple Health?

Integrating with Apple Health allows the app to automatically sync weight, body fat, sleep, resting heart rate, blood pressure, and oxygen saturation. This data can then be correlated with your tracked medications to see how your treatment is impacting your health metrics in real-time.

Who is this app designed for?

This app is built for peptide users optimizing recovery and performance, TRT patients managing testosterone protocols, GLP-1 users tracking weight loss, women on HRT managing hormone balance, athletes tracking performance compounds, and anyone serious about seeing real results from their treatment protocols.
