Will it affect my lifestyle?

Some studies have no restrictions but some might ask you to make a few changes whilst you are taking part. This might include avoiding alcohol, caffeine and certain foods, restricting exercise at certain times, fasting overnight and withholding some medicines for a while. Some studies might also have birth control requirements. You will also need to visit the clinic at specific times, so you should think carefully about your ability to do so before you agree to take part in a study. If you take any recreational drugs, such as cannabis, you will not be able to take part in one of our studies. The requirements will be clearly explained to you before you agree to participate.
