Funny you posted this, I just looked for some too. No joy. I wonder if it didn't pan out as far as SHBG/Test goes. The stuff on Examine wasn't overwhelming. Endosurge has 500mg of it, but isn't a bulk stand alone. Now, Solaray, and Swanson's have various extracts, as well as whole leaf/root.... but who knows about 3,4 Div content.
