I would also like to know what else can be done. Diluting it would be an alternative.
I have the first batch of Test-C and it was also crystallized, I then warmed it up, and all are gone. But i still get a pip for 3-4 days.
I also have the second batch of Test-E, which is yellowish. On the pictures from other reviews, however, they are very clear.
That surprises me very much. I haven't used it yet. The way I see it, it will also have pip. But i can say, the service and contact cannot be surpassed.
