| Consumer Review: This Scientific Study Proves That Andro Does Not Increase Testosterone Leves In Young Males. |
Take a look at this well designed scientific study:

The acute effects of androstenedione supplementation in healthy young males.

We examined the effects of androstenedione supplementation on the hormonal profile of 10 males and its interaction with resistance exercise. Baseline testosterone, luteinizing hormone, estradiol, and androstenedione concentrations were established by venous sampling at 3 hr intervals over 24 hr. Subjects ingested 200 mg of androstenedione daily for 2 days, with second and third day blood samples. Two weeks later, they ingested androstenedione or a placebo for 2 days, in a double-blind, cross-over design. On day 2, they performed heavy resistance exercise with blood sampled before, after, and 90 min post. The supplement elevated plasma androstenedione 2--3-fold and luteinizing hormone approximately 70% but did not alter testosterone concentration. Exercise elevated testosterone, with no difference between conditions. Exercise in the supplemented condition significantly elevated plasma estradiol by approximately 83% for 90 min. Androstenedione supplementation, thus, is unlikely to provide male athletes with any anabolic benefit and, with heavy resistance exercise, elevates estrogen.

It is true that andro (or even the nor-19's) don't work. I know because both my friend and I have used it for one cycle and have seen no gain in muscle or even an increase in energy during workouts.
