The best way to bulk is to eat more imo, you can provide assistance with test boosters (tropinol xp and intimidate srt are good options) to increase appetite. Creatine, more food, additional Protean shakes, etc.
Maintaining a caloric surplus will do more than anything else possibly can.

I have zero experience with LG products so I cannot comment on that.
