While a lot of Grenade’s American fans will be looking forward to the arrival of the reformulated pre-workout .50 Caliber. Something that was talked about last year at the Olympia Expo has crept in before the enhanced energizer, a US edition of the multi-vitamin Ration Pack. Back when the coming of the product was first mentioned, Grenade said that they had to drop the unique blister pack style for plastic bag type packaging. Another thing the brand passed on was that the US Ration Pack would include a complex not featured in the original formula. Now that the modified supplement has arrived, and making it’s way out to stockists, we can confirm that the new addition is an amino acid blend. There are a number of other changes to the product with the vitamin, mineral, and fatty acid doses. However the fifth proprietary introduction is the major one, with the blend weighing in at 850mg, and packing BCAAs, arginine, taurine, and glutamine. The last detail we have for Grenade’s American Ration Pack is it’s price, which is actually quite competitive sitting in between 25 and $30, for a full month’s 30 pack supply.
