Was taking one of my research liquids a few days ago, exemestane to be specific, and first noticed an accumulation on the bottom interior of the bottle. So I turned the bottle upside down and it is clearly undissolved powder. So, I swirled and mildly shook the bottle to see if it would mix. It does not.
Now, this has me thinking. My AIs have been pretty effective in the past, but as of late, not so much. Clearly this would indicate a problem with dosage consistency as its not possible to get the powder properly dissolved into the solution. Now that I'm aware, it's obvious when I draw the liquid and pull the powder, it is gritty.
I knew the color of the batch was off from the start but since the bottles are so dark and nontransparent, I didn't noticed the powder accumulation.
Anyone else experience this?
