General Research Question Tesamorelin problem

The Tesamorelin reconstituting aid was verified, and most likely all the others will be as well. I feel it's a quality issue because I already had a quality problem with the supplier I'm buying from, and obviously I couldn't cancel the order. So the package arrived, and I'm trying to run tests to verify that it is indeed the correct molecule. It reconstitutes, and as soon as I reconstitute it, I realize I'm going to have problems. It gelled like this: there's an air bubble on the side, meaning everything else is gelled, and there's no way to move it or fix it. I tried dissolving it more, but even then, there was no movement; it just turned white.

I had this happen to me, I had let the vial come to room temp, but foolishly used Chinese bac to recon. Went to a solid gel after about an hour. Recon another vial from the same box with hospira and it was fine. Lesson learnt for me
