About OptiPin

People on TRT, peptides, and GLP-1 medications often track their protocol across notes apps, spreadsheets, and memory — then lose the thread when they need it most: at the next bloodwork review, when adjusting a dose, or when something feels off.

OptiPin is the alternative: a single place to log injections, rotate sites, forecast hormone levels between blood draws, and see how your protocol is actually playing out — all without sending your data anywhere.

OptiPin is developed by Vitaloom LTD, an independent software company focused on privacy-first health tools. The app launched in 2025 and is actively developed: iOS-only today, with regular updates driven by user feedback.

We do not sell user data. We do not run ads inside the app. The business model is simple — a 14-day free trial, then an optional Premium subscription for unlimited medications and advanced features.

Every guide on this site is written for educational purposes and grounded in primary sources — not blog posts, not forum anecdotes. Our reference set is:

• PubMed (NIH National Library of Medicine) for clinical trials, systematic reviews, and pharmacokinetic studies
• FDA-approved drug labels and prescribing information
• Endocrine Society, AUA, ISA, and European Urology Association guidelines
• Manufacturer monographs for compounds with formal pharmaceutical data
• NHS and Mayo Clinic clinical references for patient-facing context

When the evidence is mixed or evolving — as it is for many peptides, novel GLP-1s, and dosing-schedule tradeoffs — we say so explicitly. We don't fill gaps with speculation, and we don't pretend something is settled when it isn't.

OptiPin is not medical advice. The content here is for educational reference. Decisions about whether to start, change, or stop a protocol should be made with a licensed healthcare provider who knows your full medical history.

Hormone-protocol data is sensitive — testosterone levels, peptide use, GLP-1 medications, body composition, mood. Storing it in someone else's cloud is a real risk people shouldn't have to take.

OptiPin's data model is local-first: your medications, doses, lab values, and notes live on your device. iCloud backup is optional and end-to-end encrypted by Apple if you turn it on. Nothing about your protocol is sent to our servers in normal use.

Read the full Privacy Policy for specifics on analytics, crash reporting, and what little data does leave the device (and how to turn it off).

Guides on this site are bylined "OptiPin Editorial" and dated with a last-updated timestamp. Content is reviewed against the source list above before publication and is updated when new clinical data shifts the picture (TRAVERSE, FDA reconsideration of compounded peptides, new GLP-1 phase 3 readouts, etc.).

If you're a clinician, researcher, or experienced patient and you spot something that's wrong, out of date, or oversimplified — please tell us. Corrections are taken seriously and applied with attribution where appropriate.
