The app

The community

People log more when someone notices. The community is built around that, with one firm line: others see that you logged, never what you logged.

The community in Peptide AI has three parts. Friend streaks, which keep people logging. A room for every peptide. And a weekly board. Your doses, labs and anything personal stay private. The community sees that you logged, never what.

How it works, step by step

  1. Add a friend. You share a streak: a count of days each of you kept to your protocol.
  2. Join a room. Every compound in the library has one, so the conversation stays on the compound you actually take.
  3. Check the weekly board. The community's week, in one place.
  4. Keep the rest private. What you took, how much, your labs and your body data are never shown. Only the fact that you logged.

Why social support helps people keep going

The best-known trial on this is old, small and still cited because the effect was large. Rena Wing and Robert Jeffery recruited 166 people into a behavioural weight loss programme, either alone or with three friends or family members, and randomly assigned them to standard treatment or standard treatment plus social support strategies.

A weight loss programme is not a peptide protocol, and an app streak is not a support group. The finding that transfers is about follow-through: people who know someone else is paying attention are more likely to keep going. A shared streak is a light version of that. It works on logging, which is the habit everything else in the app depends on.

Why streaks, and why a missed day is not the end

Logging is a habit, and habits are slow. In a 2010 study in the European Journal of Social Psychology, 96 volunteers repeated a chosen daily behaviour for 12 weeks. The time it took to reach a plateau of automaticity ranged from 18 days to a projected 254 days. Missing a single opportunity did not materially affect the process. That is the right way to think about a streak: it is a cue to keep going, and a broken one is a reason to log the next dose, not to stop.

The weekly board

Alongside the rooms there is a weekly board. A week is the natural unit for most protocols, with weekly injections, a weekly training goal and a weekly rhythm of side effects, and the board follows it. Like everything else in the community, it never shows what anyone takes.

Why the privacy line is where it is

Health details are personal, and many people on a protocol do not want what they take to be visible to anyone, including friends. So the community never shows doses, compounds you have logged, lab results, body data or check-ins. It shows that you logged. That is enough for a streak to work and not enough for anyone to learn anything about you that you did not choose to say in a room.

Why rooms by compound

General forums mix people on very different drugs, which makes advice hard to apply. A room for each peptide keeps the conversation specific. It is still a conversation among users, not medical advice, and each compound's page in the library carries its evidence grade for a reason: what people report and what the trials show are different kinds of evidence.

Who it is for

  • People who log more consistently when a friend can see the streak.
  • Anyone who wants to talk with others on the same compound without broadcasting their own data.

How it connects to the rest of the app

Streaks come from the dose log and the protocol planner, including doses logged on the Apple Watch. Rooms follow the compound library. Everything you log, including labs and body scans, stays out of view. The privacy and data page covers the controls on the rest.

If logging is the habit that slips for you, add one friend and share the streak. The app is on the download page.

Questions people ask

What can other people see about me in the community?

That you logged. Never what you logged. Doses, labs and anything personal stay private.

What is in the community?

Friend streaks, a room for every peptide, and a weekly board.

Does social support actually help?

In a 1999 randomised trial of 166 people, 95 percent of those recruited with friends and given social support completed treatment, against 76 percent of those who joined alone, and 66 percent against 24 percent kept their weight off from month 4 to month 10.

Is advice in the rooms medical advice?

No. Rooms are conversations among users. Each compound page in the library carries an evidence grade, and dose decisions belong with your prescriber.
