How this dataset works

A transparent pipeline from individual experience to published community data.

  1. STEP 01

    Users contribute anonymous reports

    Anyone can submit a short, anonymous report: peptide, dose, duration, demographics, and any symptoms they noticed. Email is hashed and discarded. Takes about two minutes.

  2. STEP 02

    We aggregate and publish per peptide

    Once a peptide has at least ten reports we publish the symptom counts, severity breakdown, and median onset day. Individual reports are never displayed.

  3. STEP 03

    Filter by demographics

    On each peptide page you can narrow by sex, age bucket, race, and country — whenever a cohort is large enough to meet our privacy floor of three reports per bucket.

Share what you experienced

Every report makes the dataset more useful for the next person researching the same compound. No account required, fully anonymous, two minutes.
