Only way to know would be to test it! I will send a sample to Jano and report back to the community,Doesn't matter, I had gear crash at 16/17 degree.
High concentration gear can crash....on the other hand.. test E it's not prone to crash at all. So unless it has been brewed with almost no BB it's a bit odd.
Maybe it's test C xD
I have been sent by HYB in the past Test C 300 instead of test E300 but the vials were marked as TC where these are marked as TE.
Will be sending a test this week
