we have 2 different bottles, one is bigger then the other. The bigger bottle has a darker yellow color of liquid in it. Could this be just the type of glass that is causing the colour change? Also the the bigger bottle has a Hyphen on the (organon) over the g and the smaller dosen't. The bigger one has R in the circle(registered mark) at the end of the deca-durabolin and the smaller one dosen't. What we are thinking is, that if they are real, that they were made for different countries. But that shouldn't mean that the bottles and lables look different or can they be. thanks
