stunted growth
increased aggression
skin infections
high blood pressure

Explanation:

Performance - enhancing drugs like anabolic steroids can cause increased aggression due to their impact on the endocrine system and neurotransmitters. Stunted growth can be due to many factors not directly typical of performance - enhancing drug use in the short - term. Skin infections are not a common direct sign of such drug use. High blood pressure can have multiple causes and is not as characteristic a sign as increased aggression in the context of performance - enhancing drug use.

Answer:

increased aggression
