Convincing people to participate in paid clinical trials can be complicated. Several factors can influence the decision to participate in a clinical trial, the most prominent being whether you wish to contribute to the advancement of medications.

Your participation in a clinical trial does not only benefit other patients and prospect treatments for several diseases, but you can also get early access to medicines that are not yet available for the general public. You are also financially compensated for your time and effort.

Your participation in a clinical trial can help in medical advancement, and clinical research studies cannot be conducted without you. If you are someone living with depression, then you can participate in clinical trials at CMB in California.
