4-hydroxy test is relatively new on the scene so there is little feeback from use...but what IS out there could be considered extremely positive.
In the chemical world, 4-hydroxy test is usually the intermediate for manufacture of other AAS and anti-estrogenic compounds.
Since it has a 4-hydroxy it will increase its affinity to the estrogen receptor. In this manner, the compound should prove to be very anabolic with extremely lean, dry gains. Since it is an active compound it should also prove to be very potent.
There is not any special liver breakdown protection so orally it will perform rather poorly. Other avenues of delivery should be pursued such as topical, sublingual, or intranasal.
It also makes it an ideal candidate for delivery with other compounds that are traditionally estrogenic in high doses such as 4-AD.
If anyone can add to this please feel free...
