## What is Peptide & TRT Tracker?

OptiPin is the all-in-one tracker for TRT, peptides, and GLP-1 therapy. Visualize how your doses, bloodwork, and symptoms trend together over time. Start free: track your first compound completely free - no time limit, no credit card.

Built-in reconstitution & unit calculator: enter vial size, diluent volume, and target dose to get your syringe units instantly - or work backwards from units to diluent. No math, no guesswork.

OptiPin was built out of a personal need for a smarter, unified way to manage TRT and peptide therapy - tracking injection sites, staying on top of schedules, managing multiple compounds, and keeping symptoms and lab markers in one place instead of juggling notes, spreadsheets, and reminders. It keeps growing alongside a community chasing the same thing: clarity and consistency in how they track their protocols.

### 5/5 — Best peptide/TRT tracker hands down

*2026-08-02, version 1.5.1*

This is the best peptide and TRT tracking app I’ve used. Clean interface, solid dose calculator, and the injection log actually makes sense for daily use.
I emailed the developers asking for IU support and another inventory feature. They had both ready and rolled them out in the next update. That level of responsiveness is rare. Highly recommend.

### 5/5 — Just what I was looking for

*2026-08-01, version 1.5.1*

This app tracks every medication, peptide, supplement, and intervention in my protocol — what I take, on which day, and at what time. Without it I’d be winging the whole stack. With it, consistency is automatic.

### 5/5 — Better than I imagined

*2026-07-31, version 1.5.1*

Really easy to use , helps with dosing and tells you how many units to draw. So good

### 5/5 — Perfect

*2026-07-22, version 1.4.3*

Best app ever just what I needed to track everything

### 5/5 — Best app ever esp for Menopause Brain Fog!

*2026-07-11, version 1.4.2*

Was looking for an app so I wasn’t messaging my telegram group constantly for questions! This app is amazing! Not only does it give all the info you need to reminds you not just when to take but how much and also where you pinned. Without it my menopause brain would not remember! And maths is not my strong point so the reconstitute section is invaluable! Other than social media this is my most used app!

### 5/5 — The best I’ve found

*2026-06-20, version 1.4.1*

Tried a lot of trackers. OptiPin has consistently been the most useful. Inventory tracking is very useful and helps manage a complex function. Plan to be a paid subscriber for the foreseeable future.

### 5/5 — So far So Goid

*2026-06-18, version 1.4.1*

Just started using it but it’s great for keeping track of your injection spots with different medications. I’m still learning the app.

### 5/5 — Phenomenal app

*2026-06-17, version 1.4.1*

I was starting with a few different apps to determine the best one for me. This one blew the other away. Super flexible, lots of educational tools. Advanced Injection site tracking which is importance when you pin things individually instead of as a blend. 

Had a support question and it was responded to almost immediately, with concern for real resolution which is rare. 

To “sync” from one device to another on Apple products I have to do it through ICloud backups but not a huge deal once I figured it out. When doing this inventory doesn’t update but my understanding from the developer is that this is being worked on and an update is waiting on review. Part of it is keeping your data private and in one location so only you can access it. 

I would advise to put it on the device you use most for now to get the most out of it. 

The scheduling, TRT level tracking, and ability to bring in your labs and take that in consideration is awesome.  Will keep using this one for sure. Highly recommend!!

### 5/5 — Best app

*2026-06-15, version 1.4.1*

Awesome app for tracking and logging. Interface is sleek and loads of features. Lots of customisation available and includes all possible injection sites. Love it and have paid for premium

### 4/5 — Glp concentration bug

*2026-06-14, version 1.4.1*

Home page Glp concentration is incorrect. Not sure where this figure is coming from but it’s different to the number in the medication tab which seems correct

## Version history (last 5 releases)

### 1.5.5 — 2026-08-21

Keep the feedback coming, OptiPin is actively shaped by it.

• Inventory, simplified. The day-to-day view is one screen now, with the advanced controls in their own section.
• Progress photos. A silhouette of your last shot sits behind the camera so you can line the new one up.
• Plus the usual fixes and polish throughout.

### 1.5.4 — 2026-08-14

Keep the feedback coming, OptiPin is actively shaped by it.

• Pens, in beta. Load a refillable pen with one compound or several and dose it in units. One injection logs everything in it, and OptiPin tracks what is left and roughly how many doses that leaves you.
• Nutrition from Apple Health now reads dietary energy, carbs and fat alongside protein.
• Group logging. Skip or unskip a whole group from its header, and a medication you skipped inside a group no longer vanishes from that group's sheet.
• iCloud Sync errors now say what went wrong and what to do about it.

Plus the usual fixes and polish.

### 1.5.3 — 2026-08-08

Keep the feedback coming, OptiPin is actively shaped by it.

• Your data, now on every device. Enable iCloud Sync and your doses, bloodwork and logs stay current on every device signed in to your iCloud account. Turn it off and the copy in iCloud is deleted, while everything stays on your device.
• Various updates to group logging, including splitting across times and site rotation. Logging several injections at once will never quietly put two in the same place.
• Inventory updated to show pills when editing rather than total mg.

Plus a corrected half-life for testosterone phenylpropionate and the usual fixes and polish.

### 1.5.2 — 2026-08-02

Thanks for the feedback, it keeps shaping OptiPin.

• Repeated Cycle-off: set "12 weeks on, 4 weeks off, repeating" once and every break is scheduled for you.
• Adjust Stock: correct your inventory for a spill, an expired vial, leftover you threw away, or a plain miscount, and undo it from the new Adjustments history.
• Testosterone forecasting updated with faster and more accurate calibration against your bloodwork.

Plus every-N-days schedule overrides, GLP-1 forecast improvements and other minor improvements. Thanks for your support!

### 1.5.1 — 2026-07-24

You can now reconstitute in IU - handy for insulin, HCG, and anything else dosed in units.

Also in this update:
- Removing a forecast dose from the GLP-1 view now works the way you'd expect
- Smaller fixes and polish throughout

Keep the feedback coming, OptiPin is actively shaped by it.
