### 5/5 — Just what I needed

*2026-06-16*

Very easy to use and understand. Even calculates water to use. REQUEST: A cycle calendar and dose log would be a wonderful edition. That way I could have this as my one stop pep app. Thanks!

### 5/5 — With the price

*2026-06-09*

I tried many of the “free” apps. They were super annoying trying to force me to subscribe. This app after a one time payment and does everything i want. Thanks!

### 5/5 — Actual Customer Support

*2026-06-06, version 55.5*

I thought I as charged twice but I wasn’t.  I reached out via email and Someone Got Back to me!!

### 5/5 — Update-bugs fixed.   Was working great, but now there's bugs

*2026-05-04*

Update- reached out to Support and they fixed the app in a matter of days. 
All of a sudden, when I edited then saved the calculation to a saved protocol, it deleted all the notes that were there previously, which had not occurred in the past. It's also not letting me edit notes in saved protocols.

**Developer response:** Hi Aimee,
Sorry about this! Note loss is the worst kind of bug to ship and I'm sorry you got hit by it. The new "rich text" notes functionality added in the last release caused a couple issues.

I tracked down what was happening and the fix is already pushed. The "can't edit notes" issue is also fixed.

When opening the app it should update automatically. To ensure you have the new version check the bottom of the More tab for v55.5.2

Thanks for taking the time to flag this.  
I'm hopeful you'll also take the time to update your star rating if you see fit. 

Thanks!
Jeremy

### 5/5 — Best App!

*2026-05-04*

Best app to use for calculating protocols! Customer support is wonderful! I had an issue with the app and they immediately got back to me through email. Fixed the issue and check in with me to make sure I was up to date and not was working well. I use this app so much and appreciate the help I got from them! Love this app!

**Developer response:** 💗💗💗💗💗

### 1/5 — Waste of money

*2026-04-15, version 55.4*

The app does not let you update and save  the calculator do not make the mistake I did by purchasing.

### 5/5 — Perfection

*2026-03-24, version 55.2*

You won't find a better peptide app on any app store
 Kudos guys! Great work.

### 5/5 — Needs additional features

*2026-03-24, version 55.2*

You should be able to toggle the desired dose from mcg to mg

### 4/5 — Need better blend support

*2026-03-01, version 49.3*

Have been waiting for the ability to calculate blends with more than three peps but still not available. Otherwise solid features.

### 5/5 — Brilliant

*2026-02-23*

Great App really pleased with it
