PeptideOS

Every peptide number
has a source, or it’s unknown.

PeptideOS is the all-in-one app for using peptides safely. Look up any compound and see the real evidence behind it, model exactly what a dose does in your body over the days that follow, check what interacts with what, get the reconstitution and dosing math right, and keep a private log of your protocol and bloodwork, all in one place.

And every number it shows you carries its source, or says plainly when nobody actually knows, so you are never dosing off a figure someone made up.

This is the actual half-life engine, not a picture of one. Pick a compound and a frequency and watch what the schedule does. Every other app hands you a dose; this one shows you what the dose does over time.

0
uncited claims in the dataset

That zero is not a goal, it is enforced. A numeric claim without a citation fails the build and the deploy never ships. Across 75 compounds and 50 documented interactions, every figure traces to an FDA label or an indexed study, including the 54 where the honest answer turned out to be that no human data exists.

Eight tools, one standard

Everything here is built on the same rule: it shows its sources, and it says unknown when it means unknown.

AI coachAsk anything and it looks up the sourced answer, then sets up your protocol, logs doses, keeps your journal, and manages reminders for you. It quotes only cited figures, so it cannot invent a dose.Half-life studioWatch accumulation, peak-to-trough swing, and time to steady state, computed from published pharmacokinetics. The feature no other peptide app has.Interaction checkerEvery documented interaction, sourced to an FDA label, plus an honest "nobody has studied this" for the compounds nobody has.Protocol simulatorModel your real dosing history, so a late or missed dose shows up as the dip it actually was. Private, on your device only.Certificate readerPaste or photograph a certificate of analysis and get it explained, including what it leaves out. It reads the document, it never rubber-stamps your vial.Reconstitution mathVial, water, and dose to an exact syringe reading, and backwards to check a draw before it matters. Catches the ten-fold misread.Bloodwork trackingThe labs that matter, tracked against your own baseline and your own lab range, because IGF-1 has no universal number and we will not invent one.Clinician reportOne tap to a printable summary of your protocol with the citations attached, to hand a doctor who wants to see the evidence.Rated libraryEvery compound tagged by how well it is actually characterised, sources one tap away. Approved drugs and "no human data exists" are never blurred.

Ask any other app for the source.

Everywhere else

A confident number with nothing behind it. Ask a general chatbot for a peptide dose and it will invent one, in full sentences, with no way for you to tell. That is the norm this replaces.

Here

Every figure carries its citation, one tap away. The AI briefing is grounded only on that cited data, so it is structurally incapable of inventing a dose. Where the research does not exist, it says so.

The safety half is free, and stays free

The interaction checker and the evidence tiers live free at peptidesafe.io. Charging someone to learn that a compound has documented harm is indefensible, so we do not.
