Problems with Test E started somewhere in 2008 if I remember correctly. I had raw Test E from 2004 and it was pip free even when I brew the last batch at 2019. Something either changed in the production procedure that doesn't impact the final product when it's used in a short amount of time or the underground gets "Grade B" product that doesn't cut it for pharma.Years ago, Janoshik said he tested some test enanthate raws he had kept in retention and they showed considerable decomposition. It's likely this is what's happening. Whatever it decomposes to is irritating.
I had some raws from another source years ago and the first batch was pain free and when I made another batch about 8 months later, it caused serious knots and pain.
Either way Test C or Test D are viable alternatives for long ester Test
