METHODS: In a placebo-controlled, double-blind, randomized fashion, 10 subjects received the norsteroid (11 capsules containing a combination of both norsteroids) or a placebo for 8 wk (five subjects per group). Each subject participated in resistance training an average of 4 d/wk for the duration of the study. Body composition was determined via dual-energy x-ray absorptiometry. Strength was determined using a one-repetition maximum bench press and a one-repetition maximum biceps curl. RESULTS: With regard to all measures in both groups, there were no significant changes between before and after the study. CONCLUSIONS: Therefore, in this small sample of resistance-trained men, 344 mg/d of norsteroid supplementation had no effect on strength or body composition.

They are suitable for standard CMOS fabrication and can be successfully employed in a wide range of analog signal processing applications. Two versions, based on stacked and up-down voltage-translinear loops, respectively, are described. Experimental results are
