What's up y’all! I noticed this weird crystallization occurring at the top of my HGH vial. It's generic rHGH, filtered through a .45 and 0.2µm hydrophilic PES syringe filter. I've had it sitting at 36 degrees F for 9 days now. I noticed some crystallization a few days ago, so I refiltered it into a new vial and still used it for one more day. I was out of town the last two days and came back to it crystallized again. Decided to not use this vial and reconstitute some more this weekend. Hopefully, whatever I injected a few days ago was safe . Wondering what y’all think, physical aggregation, too cold and froze?
