CMS-MS and MSIC Prep/Comp in Sheiko?

Hi, I’m not native English speaker, so I’m just wondering what does the following means:

CMS-MS Prep, CMS-MS Comp, MSIC PREP, MSIC COMP

These appear in the Sheiko routines,

thanks

It CMS-MS and MSIC Are the level of lifter. And prep is a preparation cycle to get you prepared to a comp or competition cycle. and the classifications are on the second page of this article Sheiko Shakes Up Powerlifting

Thanks!! I got it now, these article was great
