Hey;
Been out for awhile nice to be back...Came across a vial of RT EQ-400 and Test-400. They had been sitting in the same place in my safe undisturbed for 2-3 months and I now noticed a bit of sedimentation on the bottom of one. I can't remember which now, but after I shook it and it went away. Is this normal and is it safe to use? The RT expiration date is still good? What do you all think?
