That makes sense but look at anaboliclab for example the test e300 test first round tested 306mg/ml and the second was 366mg/ml or something like that. If they switch production of different compounds on the same machine I would think it'd be easier to narrow down any discrepancies throughout time of all these production runs and different compounds. It makes it nearly impossible when every single product has the exact same batch number for the past year or however long it's been when you get a low blood result or a simec test way over or a bit under from different times. I don't even know what Im getting at here lol just my own thoughts I thought I'd share. I've personally had good experiences with pcom myself, I have nothing against them.
