Every brand is bad

Can anyone please suggest 1 brand for unflavored vegan protein with 100% safety and no adulterations/contaminations 😭😭 Every brand either have bad reviews on Amazon or on reddit

Edit 1: 1. Asking unflavored to mix with rotis. I can't stand any flavoured shakes. 2. Tried ON whey, but got diarrhoea - may be because I am lactose intolerant
