The approvals, licenses and certifications tell you the differences, if any. What part of the “make up” are you expecting the manufacturer or blender to tell you?If you read my posts, you'll find that's exactly what I've stated. M1 Vs cheapo FS don't tell you a single thing about what differentiates them on the bottle. Both bottles say what spec it meets, but that's about it. It says nothing about its make up. Only the price is double or more for M1. Without lab analysis, who's to say there's any difference at all?
Are you that guy that comes on every six months or so to complain that blenders and manufacturers are hiding someting?
