About the Research +
These shirts were designed as a participant recruitment and advocacy tool for an ethics-approved doctoral study at the California Institute of Integral Studies examining microdosing LSD as a potential intervention for combat-related PTSD. The study is led by Patrick Nienaber — OIF combat veteran, 2023 Pat Tillman Scholar, and CIIS doctoral candidate.
"Whether you qualify to participate or simply want to follow the research — wearing this shirt puts the question in front of someone who needs to hear it."
— Patrick Nienaber, OIF Veteran & Principal Investigator

Before You Check Out

Combat vet with microdosing experience?

If you’re a U.S. combat veteran (not currently serving), have a PTSD diagnosis, are 21–50, and have microdosing LSD experience — your story belongs in this research. The screening is anonymous and tells you on the spot whether you qualify.
