Data from ClinicalTrials.gov (NIH/NLM). Pay estimates are approximate and not confirmed by sponsors. We do not provide medical advice. Always contact the study team directly to confirm compensation, eligibility, and risks.
Psilocybin, MDMA, ketamine, and cannabis studies recruiting healthy volunteers. Psychedelic research is expanding rapidly with university and pharma sponsors.
Flu, COVID, RSV, and experimental vaccine trials. Vaccine studies are among the most common opportunities for healthy adult volunteers.
GLP-1, semaglutide, and next-generation obesity drug studies. The weight loss drug market is booming and trials need healthy volunteers for Phase 1 testing.
Probiotics, supplements, microbiome, and dietary intervention studies. Often shorter commitments with simpler protocols than drug studies.
fMRI, EEG, cognitive testing, sleep, and neurostimulation research. Neuroscience labs need healthy brains for comparison studies and imaging.
Phase 1 first-in-human trials from Pfizer, Eli Lilly, Novartis, and more. These pay the most and are the backbone of healthy volunteer research.
