Whats with Slolvay EQ?

I just picked up two 50ml bottles of eq and they differ in colour a little and one is filled more than the other. But the both have the aluminum foil behind the label, both have the lot and exp stamped on and both posses the Solvay symbol, S with the arrow going through it. All the signs tell me that its real except for the colour and content amount. So my question is...are the both real?

go to fitnessgeared, look at the canadian section. you will find all the info, but like I told you

they seem to be ok, it is normal to differ in colors
