Earlier in the year iSatori confirmed a five flavor menu for their popular protein synethesis amplifier Bio-Gro. Originally the supplement launched in just an unflavored 60 serving powder, which was later followed by a 90 serving, double size 120 serving, as well as 200 count capsule variant. iSatori have now combined the two sets of Bio-Gro options producing a flavored bonus size bottle. The taste the brand have gone with is chocolate ice cream, and the size the GNC exclusive 50% extra 90 serving. Of course with the unflavored volume belonging to retail giant, it’s no surprise that the new chocolate 90 serving is also exclusive to GNC. Unfortunately while it is great to get 50% extra with any product. Unlike other Bio-Gro stockists at the moment GNC’s flavored option will cost you significantly more than their unflavored. The price on the chocolate tub is $69.99 or $55.99 with a Gold Card, 24 and $16 more expensive than the tasteless Bio-Gro.
