Androstenedione (4-androsten-3, 17-dione) - 5.61 % conversion to the target hormone testosterone.
19-Norandrostenedione (19-Nor-4-androsten-3,17-dione) - 5.61 % conversion to the target hormone 19Nortestosterone (nandrolone).
That means 5.6% of it converts to the target hormone AFTER bioavailability which is less than 10% for either and more like 5%
So lets do the math:
Androstenedione @ 300mg/d x 10% oral active = 30mg absorbed x 5% conversion = 1.5mg/d testosterone x 7/d = 10.5mg/w testosterone
19-Norandrostenedione @ 300mg/d x 10% oral active = 30mg absorbed x 5% conversion = 1.5mg/d nandrolone x 7/d = 10.5mg/w nandrolone
So even combined you have a total of 21mg/w of exogenous hormone. There is more conversion to estrogen that to test and nandrolone
"When androstenedione capsules first hit the market in 1996, hopes were high that the first legal product for massively elevated testosterone levels (and similarly the first true replacement for illegal steroids) had been uncovered. It did not take long, however, for athletes to realize that we did not quite have what we thought we did. "Andro" caps just didn't work the way we were expecting them to. Studies eventually showed us what was happening with this supplement, demonstrating that large doses would be needed for even the slightest elevations in blood testosterone levels. And even then our "legal testosterone elevator" turns out to increase estrogen levels better that the target hormone of our interest. Initial failings with androstenedione, at least as an increaser of serum testosterone, were repeated with its lauded successor androstenediol. Again, relatively high oral doses of this prohormone were shown to cause little or no elevations in blood testosterone." By: William Llewellyn
