Your question demonstrates a lack of understanding of bulking.
Huel isn’t a weight loss product, nor is it a weight gain product. You also don’t “take” Huel. Do you “take” milkshake? Do you “take” rice?
It’s simply a variety of foods blended into a convenient powder. It has a generous serving of protein and a plentiful supply of carbs, as well as a good helping of healthy fats. My point being, it’s literally just food, hence you eat Huel, not take it
Whether or not it is good for bulking depends on how you use it. Eat more calories of Huel than your TDEE and you’ll gain weight. Eat less than your TDEE and you’ll lose weight.
As for the question itself, I’ve had reasonable success during bulking periods using Huel. Its macro composition (30P, 40C, 30F) works well for me, although during bulking I’ll typically blend an egg or two in as well as consume chicken breasts in pasta for lunch.
Find your TDEE, eat a reasonable surplus of calories (maybe 300 depending on your height, weight and age) and you’re on your way to bulking.
