You should add a couple of scoops of maltodextrin or dextrose, essentially the same thing, to heavy cream. You can buy it online easily. It helps to give you an insulin rush so you retain the calories. Maltodextrin is a thickening agent so you may need to thin the cream down a bit with milk and you should add something to favour it such as Nesquik to make it more palatable. Also, you should ring the flavour changes so you do not tire of a course of gainer shakes. Good luck!
