Bests & Worsts Reviews from Amazon

Major issue with the lastest order. After having purchased several tubs of this unflavored pea protein and being pleased, my latest order is a dramatically different powder. In the past, I found the powder to have a pleasant enough taste and experienced no issues. Unfortunately, the lastest tub has a strong, unpleasant sour chemical-like taste. I immediately stopped drinking it after the first gulp. In addition to a horrid aftertaste, I developed a stomach ache 10-15 minutes later (have never had this issue previously). I'm not sure if something changed or if this is isolated but, in either case, it's shaken my confidence in consuming this protein.
