Is GuineaPig free to use?

Yes, completely free. GuineaPig pulls data from ClinicalTrials.gov and adds compensation estimates, eligibility matching, and category filters to make it easier to browse. We don't charge volunteers or collect payment information.

How does GuineaPig estimate compensation?

Pay ranges are rough estimates based on the study's phase, duration, and typical industry rates. Phase 1 inpatient studies tend to pay the most because they require overnight stays. These are not confirmed by sponsors — always contact the study team directly for the actual compensation.

How often is trial data updated?

Trial listings are pulled from ClinicalTrials.gov in real time. New studies appear as soon as sponsors register them with the NIH. Study status, enrollment counts, and location data are updated whenever sponsors submit changes to the registry.

Does GuineaPig screen me or sign me up?

No. GuineaPig is a search tool only. When you find a trial you're interested in, click 'View on ClinicalTrials.gov' to get the study team's contact information. You'll go through the sponsor's own screening and enrollment process.
