I got a new batch of matte green cap 10mgs in early July from my fav reliable china vendor. This is the same vendor I used before. I have just now taken them out of packaging and reconstituted the first one. When I added the BAC water the puck dissolved immediately leaving a few chunks like usual, but those chunks dissolved within minutes without having to roll them. They weren't packed into the edge of one side like before, they started floating freely immediately.

Before with the matte black caps there was a chunk in the corner that didn't dissolve easily and usually took a good while sometimes up to 10 minutes to dissolve. I had to roll it vigorously on my counter for a while to get it dissolved completely.

I'm troubled by the difference. Is this normal or were the other 9 vials normal?

I actually have one matte black cap left that I could do a side by side to show the huge difference with the matte green cap but I'm worried about leaving them unused for a few weeks reconstituted.
