Who makes Peptiday

Peptiday started from one question people on a protocol keep asking: what changed after I changed something? Existing apps logged doses, but none lined up sleep, HRV and weight from before and after a change and said honestly how sure you can be. So Peptiday does that, and keeps your records on your iPhone while it does.

What Peptiday won't do

• Suggest a dose, compare your dose with anyone else's, or tell you to start, stop or catch up.
• Sell peptides, link to sellers or earn commission from them.
• Show inflated ratings or user counts.
• Hold your records hostage. Without a plan you can still read and export them.

How the library is written

The peptide library has 34 entries and there are 33 lessons. Each entry is written from primary sources: FDA labels and records, trial publications and peer-reviewed studies. Every claim links to the sources behind it and states what those sources can't tell you.

Each claim is placed on the evidence ladder by the kind of study behind it:

• Human trials. Controlled studies in people.
• Human observational. People, without a control group.
• Animal studies. Mostly rats and mice.
• Lab studies. Cells in a dish.

A claim on a higher rung says more about people. The count beside each rung covers the studies cited in the entry, not the whole literature. A higher count doesn't mean a compound works.

What the library is not

Entries are editorial summaries of their sources. They have not been reviewed by a clinician, and they say so on every page. They don't include dosing protocols, and regulatory statuses describe the records available on the date shown. Statuses change, so check the linked source before relying on one.
