Which of the following is NOT a side effect associated with pro-hormones?

The choice stating weight loss is indeed the correct response. Pro-hormones are substances often taken to increase muscle mass and strength by boosting levels of hormones such as testosterone. The primary side effects associated with pro-hormones typically include conditions resulting from increased hormonal levels, such as breast tissue enlargement, hair loss, and prostate swelling.

Breast tissue enlargement, or gynecomastia, can occur because pro-hormones may convert to estrogen in the body, leading to such hormonal imbalances. Similarly, hair loss can be a side effect due to the influence of androgens on hair follicles, leading to more rapid thinning or loss of hair. Prostate swelling is also a concern as elevated testosterone can stimulate prostate tissue, leading to growth and discomfort. These effects highlight the intricate connection between hormonal levels and various body systems.

In contrast, weight loss is not commonly associated with pro-hormone use; rather, individuals typically use these substances to promote muscle gain and overall weight gain in terms of muscle mass. Therefore, weight loss stands out as it does not align with the expected outcomes of pro-hormone supplementation.
