I am not an expert, & would normally just post the video and let people decide, but in this case it was an exact match to the control. The drop in first test was slightly larger, so color may appear slightly off in video, but in person it was exact after a little more time passed. I find it really hard to match colors with the pics from LM website. It really seems to depend a lot on how much time passes & sample/concentration. While it uses a lot of tests, this way seems a lot more accurate to me. I don't care what color it turns if I am 100% sure one sample is legit and the two samples match exactly and change color at same exact rates. In the case of this Sustanon, I would say it is GTG IMO. While one was Mexican and one was Egyptian, the oil weights/colors were the same. I would tend to think Sustanon would be a tough one to get a + labmax from a knock off as well. If you think about it, in a knock off test E you could just add a little test E and you would get a positive labmax result for Test E. To get Sust to match a legit Sust sample, I would assume you would have to add all 5 esters in the right proportion to get the color to match that closely. This is my opinion, but I will be ordering some more of his Organon Nile Sust.
