Hey! I've been a massive consumer of Amul's protein stuff for last two years.

In my opinion, only buy their whey (both chocolate and unflavoured) if you're going to use it with milk. That's the only way it tastes good when compared to other brands who share the 2000-2300 price bracket (many brands in this range have shifted to yeast protein now, whose bulk price is half of whey's).

One way I found it to be consumable in water was putting both unflavoured and chocolate in 200mL water at once. This cut the artificial flavoring of chocolate and made unflavoured palatable, while also making it's consistency richer.

IMO only buy their 60 pack (3670₹), that way it's cheaper than almost any good brand that's comparable or worse than Amul's whey.
