A grease cannot be pure molybdenum disulphide, because that is a powder, so even the so-called moly grease simply contains an often surprisingly small amount of MoS2 in a grease carrier.

If I was marketing a grease containing MoS2, I might just as well name it MD, for molybdenum disulphide, as anything else. Similarly, MS in the name might simply stand for 'more suckers' or 'makes sterling'. As I said, it stands for whatever the manufacturers want it to stand for and should not be taken as a reliable indication of content.
Why do so many call their lubes MS
Even special airgun lubes like these are also called MS
