Keep in mind 4AD is a pretty wet compound. I don't personally see an advantage to using it over testosterone.
I get the same side effects from 4AD that I do from test (as would be expected to an extent). The partitioning just isn't as good. In practice I find it not to be very anabolic compared to straight testosterone. However, keep in mind I ran it as a dermal (sold the cyp I had pre-ban).
It is a cool little ph....best used with other steroids though as noted previously.
