Blackstone Labs, the brand from the same company behind Prime Nutrition, have shown off a beta sample of an upcoming supplement. Following on from the discontinuation of all the brand’s products affected by the pro-hormone ban, Blackstone are looking to get in to some of the more mainstream markets. While the brand are already in a number of popular categories, they have yet to take on the protein competition. That is all about to change as the Blackstone have uploaded an image of a beta bag labeled with the temporary title Isolate. Also printed on the label is the sample’s flavor in chocolate, its serving size of 31g, and a short instructional sentence directing users to mix the powder with 4 to 6oz of water. Not much else has been said about the Blackstone Isolate outside of the details on its small bag, with the only other fact being that the brand have yet to finish flavoring the supplement. There’s no word on when the isolate protein will be launched, although based on the stage Blackstone are at we can’t imagine it’ll be arriving anytime soon.
