Yep it's a slight crash. Part of why I don't brew large batches. I don't use super solvents and stuff will crash after a few months. Both tren's will do it and the deca will also. A simple reheat while swirling will fix you right up. Once it's in a vial my recommended reheat process is the lowest setting on stove in a small pan. Let it sit there for about 3 min then swirl for 10-15 seconds. Repeat until all crystals are gone. Also as ironcarpenter said, I like heating my gear before I use it each time just to add in pinning. For that I just wrap it in a heat pad beforehand.

Get a coffee cup. Half full of water. Enough not just cover you vial 3/4. Heat water for 30 -45 seconds. Put vial in let sit for less than a minute. Pull.out gently swirl. And your good. If it gets worse and not better. Toss it. Just heat it up. It will pin better also. Your good

Honestly it looks fine to me but your picture quality isn't the best

What chc253 said. But if that dont solve the problem. Toss it, its not worth the risk homie.

Try reheating with a hair dryer, if its juat crashed it will come back.
