Test colour?

Hello, my 3 vials of Test Enanthate by Body Nutrition came in today. Getting preprepared for my cycle starting in 2 weeks. But I have a small concern with the colour of the test enanthate. This is my first time with test enanthate, the test I dealt with before had a more yellow/brown colour to the test. While the test enanthate is lighter in colour, still has the yellow/brown, but not nearly as much as others. Should I be concerned? Is it normal? Is it less potent? Has anyone dealt with body nutrition before, and are they good?

Thanks for your time.

The color of test is entirely based on the type of oil used.
