Usually if GNC does not allow the military to see them manufactor the product, then they do not get sold on base, this happened with Monster Milk, until they allowed the military to see how th eproduct was made, I guess GNC thought the military would steal the formula, but the military did not want soldier taking a product that may have steriods in it.
Here is what is in your item:

If the military has not seen it manufactured, it cannot be sold at GNC, just go off post to a GNC near by and get it instead.
