As BPI’s much more modern looking supplements slowly make their way out, it appears the brand have given one of their products a little more than an updated label. BPI’s stimulant driven thermogenic B4, originally the first and only Diamond Series supplement, has been spotted in a double size bottle. As promised the formula has remained exactly the same, although at GNC instead of having a total of 30 capsules like it’s predecessor. The bright blue, black and white B4 has twice as much with 60 capsules, working out to of course 60 servings. The popular retailer do still have the original B4 in stock, which when compared to sees the rebranded fat burner come out more than 20% cheaper per serving, or just over 25% cheaper with a Gold Card. The super size BPI product will not only save quite a bit of money, but also obviously supply you for a little longer packing a whole two months worth.
