The Natural Vanilla flavour is superb. It's distinct from standard vanilla.

I use Optimum Nutrition just because in terms of brand reputation they probably have the most to loose. Cheaper alternative is BAAM. Wouldn't trust Lazada sellers with supplements, unless it's an official Lazmall brand. My favorite protein powder was MyProtein unflavored, but last time I ordered I had to go to customs to pick it up and they had opened the pack and half the protein powder was out of the box, and they're no longer even shipping to Thailand.

What's your take regarding the safety/contamination aspects? MP is my favorite as well taste-wise (cookies & cream is to die for). I know they have an Origin range that came out recently that's meant to be more "checked".
