Optimum Nutrition were quick to announce and preview their Arnold Classic launched Platinum Tri-Celle Casein. Unfortunately they have not been so quick to actually getting the supplement on to shelves. It was almost 3 months ago that the brand dropped the bomb, and unveiled their new but arguably unnecessary casein formula. On the bright side most of the product’s details have already been revealed with a 25 serving tub, MicelleXL technology, and it’s three gourmet flavors chocolate decadence, strawberry indulgence, and vanilla bliss. For those eagerly awaiting the slow release protein, Platinum Tri-Celle Casein will be within reach very soon. As Optimum Nutrition have promised a launch date of late spring, which should see the supplement surfacing in the next few weeks.
