I just got mine around same time as you but not cn batch.mine is m batch and is verified when typing the numbers in on there site.mine is a bit clearer that that,but I can always taste and tell if it's real and strong..been doing it to long and after awhile you can taste and tell.looks good to me though.

Oh yeah bro I'd say you have nothing to worry about as far as color ... when you said yellow I thought you meant like the test I have in my pics.As far as that little bit of tint I wouldn't trip but as far as lot numbers the only way to really tell is pull bloods or gauge your results (bloods more ideal obviously). I think your good.

I've had lots of GP Test E with the yellow hue. I've never had a problem.
