How long will my Soylent last after opening or use?Updated a year ago

Opened bottles of Soylent drink must be kept refrigerated (40℉ or below) and consumed within 72 hours.

Soylent Powder that has been prepared (i.e. mixed with water or other ingredients) must be kept refrigerated (40℉ or below) and consumed within 48 hours. Please consume or discard any blended powder that was chilled within two days. 

If you have been refrigerating your blender powder or product and it smells or tastes “off,” please do not consume. It has likely expired and should be discarded.
