Is this the study Anabolic Andre? They seem to report success at selectively inhibiting the enzyme.
They even give instructions on how to make the inhibitors from raw substances.
Not sure I'd be willing to test it on myself though.
If it worked it would reduce 3a-HSD in muscle cells and allow DHT to bind to the AR receptors in them as much as it does in other tissues.
This would make taking Test a much more potent AAS for our uses and would even allow taking DHT straight and build serious quality muscle.
