This compound is actually only a weak agonist of the androgen receptor (AR), with poor binding. It follows, then, that its value must mostly come from non-AR-mediated effects. It is therefore a Class II steroid. Since it is not very effective in activating ARs, it should be stacked with a Class I steroid that is effective in this regard, such as Primobolan , Deca Durabolin , or trenbolone acetate . There is no point in stacking it with Anadrol, which has similar activity, as one ought to simply use the more appropriate drug. With testosterone or Deca, Danabol/Dianabol is to be preferred. Or with Primobolan or trenbolone acetate, Anadrol is to be preferred (though Danabol/Dianabol is still a good choice) because Anadrol does not aromatize.
