Pretty good i think, they are shortdated 31/3/2011 although that is a best before. I have had their products before a few months after the date expires and the taste and everything else is fine still.
Worth a go if you have been thinking about trying. I cannot vouch for the Orange flavour although i have just ordered 3 tubs for myself at £41.50 plus i used my reward points.
If you love or hate maximuscle i think this is a cracking price for any supplement with the ingredients this one contains.
here is the link to the Promax extreme (in date) where you will see the nutritional values http://www.maximuscle.com/promaxextreme
Remember that link is not the deal link but it is the same product (Long date)
Click go to deal as per usual to get to the short date one :-)
failing that http://www.maximuscle.com/promotions2010/10andunder.html
Hope you like the deal, if not.... apollogies!
All the best all!
