My All-in arrived on Saturday and I immediately mixed up a dose. Took a big swig and all I taste is go old Citrulline malate, sour but not undrinkable. So I figured on my next dose I will mix the contents in the bag thinking maybe the flavoring settled in to the bottom of the bag. Mixed up the batch, this time it was slighlty sweeter but definialy not watermelony. I am going to buy a few of those lemonade sachets to drop in the bottle they should work really well with the tangy and tart flavor. I will just order lemon next time.
