I have lots of sus 300 which I will be taking soon. I now have a new reason to worry about my gear. I've worried about it for a long time b/c it's unmarked. I was told it was European sus300 by someone I trust, and I freezer tested it, and it passed, but I had someone who knows his juice look at it and he said it didn't look thick enough to even be 250. Is it possible that a thinner oil was used, or do ya think I'm just SOL? It's in a 10ml brown vial with a red cap. Thanks bros. A little more specific, it is not much more viscous than water. Anyone have any ideas??
