Strange crystallization

[SuperJolanda]

Hi guys, quick question.

Receiver my gear and I kept it in the refrigerator and no where near freeze temperaturen.

All vials are perfectly fine except two Tren E vials. They have some weird crystallization in the bottom

I have never seen this before. Can i still use them or are they worthless now? And How could this happen? I mean... the others are perfectly fine its just 2 vials out of 6 that have this.

Hope someone knows what this is and if i can still use them. Would be a nummer if they are worthless now. Still weird it only happens to two out of 6 tren.

Best regards

P.S. They are outside the fridge for hours now. The crystals do not disappear they just sink to the bottom. Guess they are unusable now? If I buy new, How do i know this wont happen again?... and did I do something wrong?
