The original poster sees an unknown spot on a freshly mixed vial that was previously frozen and wants confirmation it is safe to use. Most replies identify it as air bubbles and suggest swirling or shaking the vial, then waiting to see if the spot vanishes. A couple of users add that letting the vial warm up first or venting during mixing helps prevent bubbles.
What this discussion establishesNothing here is advice.
I recently mixed up a fresh vial of T30 after taking it out of the freezer. There's something stuck on the side of the vial, and I'd like to know if it's still okay to use for injection.
Seems like air bubbles from what I can tell. Try giving the vial a gentle swirl and waiting a bit to check if they go away.
Allow the vial to reach room temperature first, then swirl it softly. It appears fine otherwise.
Sure, set it aside for a day or two, and if it doesn't dissolve, a swirl could assist.
Give it a good shake and it ought to vanish. Shaking does no damage; that's just a myth.
Appears to be air bubbles. When reconstituting, I release the pressure in my vials to remove the vacuum, which prevents bubbles from forming.
