You need to get the sensitive e2 test, otherwise tren and deca both read as e2.
No. Only Trenbolone shows up as E2. Nandrolone does not and will reflect a true E2 reading. Guys on Nandrolone only will have low E2 usually. Unless they are on very high amounts.
I always thought both caused skewed results on non-sensitive assays. Look at that, I learned something new today.
