My package that came in yesterday (I ordered last week), has batch numbers on the Test Cyp, and even on their bacteriostatic water.
Current batch of test cyp that I have doesn't have any related testing, but I know he said it's on the way to Jano. So I know for sure he followed through with including batch numbers to his products. Just need to be patient.
My two cents: I haven't been on meso long enough for my opinion to be respected, but based on my anecdotal experiences, primal is extremely good at responding to direct messages with any questions you may have about products. So if people have concerns in specific they'd like answered whether it be about a previous batch or a new one, i'd suggest DM'ing him those specifics and he will get back to you. I can't imagine it's easy responding to hundreds of DM's / emails daily AND staying on top of every single response in this thread, so some "concerns or questions" might just be getting lost in the thread.
