I'm pretty sure drol has such a poor affinity for the AR it's not even measurable.I was told at site injections ... it will give you incredible power and growth due to its strong AR bindings.
You're right that the metabolites can have high affinity. Thus Anadrol could be called a pro-hormone since it doesn't seem to have any intrinsic activity.that whole ar binding thing is a bit goofy. in the body the steroid is metabolized into different compounds, which have different affinities to the ar. a portion of oxymetholone converts to methyl-dht (mestanolone) which has a high ar affinity.
in my experience the whole bill roberts theory on stacking was sorta semantic and never really panned out. according to it,, eq and deca do the same thing and are interchangable. yuh
