Any chance of getting the blood test run again? That seems damned near impossible. Conversion to estrogen wouldn't cause test levels to drop that low. The body makes an attempt to stay in homeostasis by converting test to estro to try and keep the ratio roughly equal to what it is normally. (well it's not really that intentional but you get the idea) And endo test shut down wouldn't cause much of a drop because you are injecting a pretty heavy dose.
I'd personally go with an SERM for a few days to blunt estro that is currently active and start an AI to prevent further conversion. Assuming you have both on hand of course. Just my $0.02.
) there are really no other benefits for injecting winny. It's still gonna pass through hte liver and possibly elevate enzymes. Many people think that since they're injecting a methylated compund that their liver won't be effected...this is false.
