Oh I've been curious about this too! Have you tried it yet? I'm still getting used to all the different health drinks here, so I'd love to know if it's actually good or just hype lol

I tried the Herb Barley Shake a year ago because I wanted to gain weight, and I gained 5kg and have maintained it since.

Herb barley is great. It told me why I wasn't gaining weight and what I needed to do to gain weight, and while I was practicing that, I drank the herb barley shake and gained weight healthily~
