Weight gain supplemets

hello, does anyone know of any weight gain supplements that aren’t too high in sugar and won’t spike my levels. I’ve tried to find some but worried the ingredients and the sugars will make me sick, e..g the milk or the maltodextrin. I’ve looked at complan but it seems to be really high in sugars.
I’m worried because i once tried freusiben jucy and fortijuce and theybmade me feel extremely shaken and physically sick and like I was going to pass out with in hours of drinking them and I don’t want to feel that way again.
Any help is much appreciated
