Possible Side Effects

Like all medicines, oral anabolic steroids can cause side effects.

Potential effects include:

• Suppression of natural testosterone production
• Reduced fertility
• Testicular shrinkage
• Menstrual irregularities in women
• Virilization in females (such as deepening of the voice or increased body hair)
• Gynecomastia with certain anabolic steroids

Some hormonal changes may be long-lasting or permanent.

Are oral anabolic steroids harmful to the liver?

Some oral anabolic steroids may place stress on the liver, particularly those that are 17-alpha-alkylated. Regular medical monitoring is recommended when they are prescribed.

Do oral anabolic steroids have side effects?

Yes. Side effects may include hormonal changes, liver problems, cardiovascular effects, acne, mood changes, and fertility issues.

Can oral anabolic steroids be purchased without a prescription?
