It would be helpful to know some bare minimum info like who you ordered from, what you think you might’ve ordered recently, if you’ve done any reagent testing on it, etc lol. As you yourself mentioned, just looking at this picture, it could quite literally be anything from brown sugar, to D(ee)MT(ee), to dirty bootyhole m3th, to an extremely potent z3n3, or anything in between.
If you don’t want to, or can’t send it to a lab, please at least get a reagent test kit that comes with, at minimum (but preferably all), a few of the following test kits: Marquis, Mandelin, Mecke, Liebermann, Zimmermann, etc.. this would be step 1 in helping you at least narrow down and partially rule out (though never 100%) one chemical class from another.
