It appears that Bodybuilding.com has just introduced two new stacks for its Jym supplement line. You have the four piece Complete Package and the much smaller two product Essential Stack. The former is made up of Pre, Post, Vita, and Pro Jym, with the latter packing just Pre and Pro Jym. As convenient as they both sound, unlike most stacks neither of the new Jym releases actually save you any money. With the Complete stack at $124.88 and Essential at $68.13, they work to exactly what you would pay at Bodybuilding.com if you purchased them all their supplements individually.
