I can't test my products every single moment, so I do routine testing. My supplier also provides their own HPLC testing, but thats like any brand saying they are the "best" in something. Having a large amount of sources who are supplying from me and testing frequently allows me to know where my product stands at each moment. I personally aim to test each batch with ten key products such as Test E, tren E, etc. The populars. It stands to say I came in here without any present tests(done by myself), hoping the recent bloodwork done on our products and testing by the SST community would back me up, such as WinterPharm's recent tests on 12/6.
