Yes. I had this issue using 2 sources It's not only a problem at ppl. It's a common issue with test e now and that's why if I want to use a long ester I chose cyp. Test C it has similar half life but no pip and you can't brew at high dosage but if you use low dose shouldn't be a problem that. I will not switch back to test e again.
I heard that heating oil at 60⁰C for 25-30min should resolve pip issue but never try it.
