efficy of 4-androstenediol via topical or oral application

I was told by bill to use some androsol and was wondering two things: 1) without being biased, are there other supplements that contain 4-androstenediol that would be basically as effective for the purpose of increasing libido during recovery(of course with clomid application) 2) does it make a difference on how i take the 4-anrostenediol ( oral or topical) and how it’s metabolized? If so, is there a compensation for the lesser of the two? thanx
