[Changes in the endogenous hormonal background due to anabolic steroids]

Area of Science:

• Endocrinology
• Sports Medicine
• Biochemistry

Background:

• Anabolic steroids are performance-enhancing drugs with significant physiological effects.
• Understanding hormonal changes induced by anabolic steroids is crucial for assessing their impact on health and athletic performance.

Purpose of the Study:

• To investigate the effects of metandrostenolone and ecdisterone on blood plasma hormone levels.
• To compare the hormonal responses to these two distinct classes of anabolic steroids.

Main Methods:

• Blood plasma samples were analyzed to quantify hormone concentrations.
• Hormonal changes were assessed following both single and long-term administration of the studied compounds.

Main Results:

• Metandrostenolone caused a transient increase in corticosterone and a decrease in somatotropic hormone (STH).
• Long-term metandrostenolone use led to reduced testosterone levels.
• Ecdisterone administration resulted in an increased corticosterone level, irrespective of administration duration.

Conclusions:

• Elevated corticosteroids may enhance biochemical processes in skeletal muscles during exercise.
• Altered corticosterone:testosterone:STH ratios from long-term metandrostenolone use could lead to adverse effects.
