I was using one or two scoops a day. Please check the remaining amount in the photos. (It's filled up to about the fold in the third photo.) I don't know the exact weight, but I haven't used much since I bought it, so I think there's quite a bit left. The expiration date is February 2027. No returns or refunds, please.
