How often can I take part in trials?

For your health and safety it is important that you do not take part in trials too often and especially not simultaneously i.e. enrol to take part in studies with us and at other centres. If you have taken part in a clinical trial and you are unsure about when you can next safely participate in another one, we are always more than happy to discuss this with you.
