I did about the stupidest thing I've done since I've been mixing. Quite awhile back I poured the rest of a 120ml bottle of 100mg into my working bottle in the frig. I put a bit of soap in the empty bottle, shook it and put it on my closet floor. Fast forward and I poured that bottle into 2 mixes before I remembered what was in it. I dumped them out and remixed them this morning. Won't do that again.
