i dunno mate, i know ur into the weight lifting n all that so obviously u'll be more in favour of whatever it is but my mate plays football semi pro and was taking weight gain stuff a while ago.

we were all taking the piss out of him cos it basically had the same nutritional values as nesquick but he was payign 40 quid a tub for it but regardless he kept takign it and he started going mental like having major mood swings and being really aggresive whereas before and after taking it he's laid back and not bothered about anything.

not sayign it was a direct result of the weight gain sdtyuff but there's a ton of shit in it that no one really know what it is or does and it'll mess with ur body and ur head.
