Questions
How does it work out run-out dates?
From the stock you entered and the schedule you set. If something is missing, it tells you what it needs instead of guessing.
Is Peptide Library free?
Yes. Logging, schedules, reminders and the journal are free on every platform, with limits on inventory and progress photos. Pro removes those limits and adds cloud sync across your devices.
Which devices does it work on?
iPhone, Android and the web. Sign in with the same account and Pro carries across all of them.
Does Peptide Library sell peptides or give medical advice?
No. Peptide Library is software for organizing your own records. It sells no peptides and gives no medical advice.
Who can see my records?
Your logs, schedules and journal are private to your account and are never used for advertising. Our privacy policy has the details.
