Journal ArticleDOI
High-density lipoprotein cholesterol is not decreased if an aromatizable androgen is administered.
TL;DR: There were no changes in total cholesterol, triglycerides, or insulin in any group but, in the MeT group, apo AI levels decreased and low-density lipoprotein cholesterol (LDL-C) increased.(ABSTRACT TRUNCATED AT 250 WORDS)
Journal ArticleDOI
The administration of pharmacological doses of testosterone or 19-nortestosterone to normal men is not associated with increased insulin secretion or impaired glucose tolerance
TL;DR: It is demonstrated that pharmacological doses of testosterone and the administration of 19-nortestosterone for 6 weeks do not impair glucose tolerance or alter insulin secretion in normal men.
Journal ArticleDOI
Psychological and serum homovanillic acid changes in men administered androgenic steroids.
TL;DR: The influence of ND on the dopaminergic system, which is reflected in increased serum HVA, appears to be independent from the psychological effects which were produced by both androgens.
Journal ArticleDOI
Comparison of the effects of high dose testosterone and 19-nortestosterone to a replacement dose of testosterone on strength and body composition in normal men

TL;DR: The data suggest that high dose androgens increase body mass and may increase strength in normal men but, except for a consistent weight gain with greater than replacement doses, the detectable changes were highly variable and relatively small, especially in comparison to the significant alterations which were observed for other markers of androgen action.
Journal ArticleDOI
Plasma atropine concentrations via intravenous, endotracheal, and intraosseous administration
TL;DR: The endotracheal and intraosseous routes provide alternatives to the intravenous administration of atropine when intravenous access is limited or not available.
