Super easy and reliable peptide tracker ⭐️⭐️⭐️⭐️⭐️
MADHOUSE34!
Ive been using PeptideJournal every day and it’s made tracking so much easier. The calculator is accurate and takes the guesswork out of dosing, and I like that I can set reminders so I don’t forget. The interface is clean and simple, and I really appreciate that it keeps all my logs in one place. Definitely worth it if you want something reliable and easy to use.
Developer Response
Appreciate you sharing your experience. It’s great to hear the calculator and reminders are helping take the guesswork out of dosing and that the simple interface is working well for you.
Best calculator / calendar app I’ve found to track dosages

I usually don’t write reviews but this app was everything I needed when it came to tracking my dosages and I’m glad I gave it a chance on a whim. It calculates everything for me which makes keeping track so much easier especially if you’re using more than one P multiple times a week.
Developer Response
Thanks so much for the support! Happy to hear it’s making things easier for you — that’s exactly why I built it. More updates to come!

Great for keeping all research doses logged, and inventory tracked. Easy to use. Great customization for all vial details such as batch numbers, lot codes, brand, etc.Inventory tracker is great! Really like the reminders that automatically notifies when running low. Can set custom inventory level trackers!Highly recommend for researchers who enjoy staying organized.
Needs to do better

Overall good app, but misses the mark on some key areas. Like History. Archived vials don’t show up in your history, but they should! Otherwise if you want to see your true history you gotta unarchive all your past vials and that leads to a huge mess when trying to add a past dose. This app also missed the mark on Analytics. Pie charts don’t mean squat. Instead tell me stuff like mg per week / month of a peptide… or cycle data,etc
Developer Response
Thanks for the detailed and thoughtful feedback — this is exactly the kind of input that helps improve PeptideJournal.You’re absolutely right about History. Archived vials should still appear in historical dose entries, and that behavior has now been fixed. History will now always reflect all logged doses, regardless of vial status, without requiring unarchiving.You also called out Analytics, and I agree with you there as well. I’m actively working on expanding this beyond visual charts to include more actionable data, such as mg per week / month, cycle-based summaries, and other usage metrics that are actually useful for tracking protocols.These updates are currently being prepared for TestFlight, and I’d love to invite you to test the upcoming build if you’re interested. If you’d like early access or have additional suggestions, feel free to reach out directly at support@mypeptidejournal.comThanks again for taking the time to write this — feedback like yours directly shapes where the app goes next.
