Originally Muscle Sport only launched its Lucky Charms inspired flavor Lean Charms in Lean Whey Revolution’s larger tub size, the 67 serving 5lb. If the flavor proved to be popular the brand did say it would then put together a smaller 2lb size, something Muscle Sport has in fact now done. While Lean Charms Lean Whey did only just go on sale at the beginning of the month, the flavor has already proven itself enough to get the second size. While the smaller Lean Charms has yet to be added to the brand’s own website, it has been spotted in retailers. You can also look forward to seeing our review of the flavor soon, as we were able to pick up a tub at the Olympia last week.
