Steroid May Cause More Harm Than Good To Middle-Aged Men
- Doctor's Guide, 11/6/00 - "During
the 28-day study, researchers investigated the effects of ingesting 100 mg
of ASD three times a day compared to placebo in 56 healthy men between the
ages of 30 and 56. The investigators did not find an increase in total
testosterone levels, but did find a 40 to 50 percent increase in free
testosterone levels and a 55 to 110 percent increase in dihydrotestosterone
(DHT). DHT is a powerful form of testosterone that does not have an effect
on skeletal muscles, but instead it can cause the prostate to enlarge ...
The ASD group also experienced a 55 to 80 percent increase in estrogen, the
female sex hormone, which can cause breast enlargement in males and may have
other negative health consequences."

- Doctor's Guide, 2/8/00 - "the
group of men who took 300 mg per day had an average 34 percent increase in
testosterone levels on the seventh day of the study when compared to their
baseline levels taken before the study began. There was a 128 percent
increase in estradiol levels. In addition, the study showed an increase in
estrone (another estrogen hormone) among those taking andro. Study
participants taking 100 mg. per day showed some increases in estradiol
levels but not testosterone levels. The authors say the increases were not
statistically significant"

Abstracts:
- Effects of androstenedione-herbal supplementation on serum sex hormone
concentrations in 30- to 59-year-old men - Int J
Vitam Nutr Res 2001 Sep;71(5):293-301 - "Subjects were randomly assigned to
consume DION (300 mg androstenedione, 150 mg dehydroepiandrosterone, 540 mg
saw palmetto, 300 mg indole-3-carbinol, 625 mg chrysin, and 750 mg Tribulus
terrestris per day; n = 28) or placebo (n = 27) for 28 days ... Serum
concentrations of total testosterone and PSA were unchanged by
supplementation. DION increased (p < 0.05) serum androstenedione (342%),
free testosterone (38%), dihydrotestosterone (71%), and estradiol (103%)
concentrations. Serum HDL-C concentrations were reduced by 5.0 mg/dL in DION
(p < 0.05) ... While the ingestion of androstenedione combined with herbal
products increased serum free testosterone concentrations in older men,
these herbal products did not prevent the conversion of ingested
androstenedione to estradiol and dihydrotestosterone"
