Two different friends got bottles of the same test from the same supplier, one took it and had good results the other kept it for a few months and now it looks settled out like winny, all the powder at the bottom. We ran it under warm water and shook the crap out of it, that broke it up some but there are still a few particles at the bottom. Is that a sign of super old gear and is it still safe to use just not potent? The gear is from mex and had no lot # or exp date. Thanks for any input.
