So I started my monkeyratasaurus on this today as an add on to his pre-workout at 12.5mg. It gave him a great pump in the gym. I will keep it at this dose the first week before upping it to 25mg pre-workout. I will also be using this for his "cardio". But will be using a full dose for that. So far so good in the gym cant wait to see how it works in other areas. Thanks again PRE
