Everybody is different, either in height, weight, bodyfat or metabolism. This can vary how it may effect you as you build up the cbd in your system. As a first time user, we would suggest taking it slow, using lower amounts and see how you feel as you go (not exeeding 70mg a day). If you are taking any medication, especially certain anti-seizure medication, or are not sure about taking CBD, it is always worth speaking to your doctor before adding it to your routine.
