In my project I intend to find out if androstenedione actually performs as claimed by producers of the drug. Many athletes take it and all say that it does help them to gain bulk. Many have had large increases in weight and muscle. Most professional sport organizations have banned it and claim it to be a steroid, but it is allowed in high school sports and in major league baseball. I think it will increase the weight of the rats.
The rats were placed in their cages. Each day the rats were weighed. The rats were then given the appropriate and equal amount of androstenedione. They were then reweighed and the process was repeated every day.
The rats that received the androstenedione did experience weight gain. All of the rats taking it increased by one or more grams.
