Baris Bingor is an independent iOS developer and the creator of Peptly. He builds focused, privacy-first utility apps. Peptly is a private log and tracker for the peptides people already use — each entry exactly as typed, with Today, reminders and injection-site rotation — and this website adds the reconstitution math, in a free calculator that runs in your browser.
What this site is — and what it isn't
To be clear about the boundary: Baris is a software developer, not a clinician, pharmacist, or medical professional, and holds no medical credentials. This site, thepeptly.com, exists to do reconstitution arithmetic and to organize reference information; the Peptly app exists to keep a private log of what you enter. Neither is a source of medical advice, a dosing recommendation, or a prescription. Any decision about human use belongs with a licensed clinician.
Why the content can still be trusted
The site is trustworthy for two specific things: the math and the sourcing. Reconstitution is verifiable arithmetic — concentration equals vial mass divided by the water volume added — and every worked example on the site is computed, not guessed. Where a page states a fact about a compound (approval status, mechanism, a clinical-trial result), that fact is drawn from a primary source such as the FDA label database, peer-reviewed journals like the New England Journal of Medicine, or PubMed, and is cited on the page itself. Claims that can't be sourced aren't made.
Privacy by design
Peptly keeps your records on your phone. There is no account, no sign-in and no cloud sync: your log, schedules, weight entries and vial notes never leave your phone. The app does send usage analytics and install attribution (AppsFlyer uses your advertising identifier only if you allow tracking); the privacy policy lists exactly what. That privacy-first design is deliberate, not an afterthought.
