  • The "experimental steroid" John secretly bought from Ricardo Diaz is stored in crates labeled "methylphenidate", which is not itself an illegal drug; methylphenidate is sold in pill and capsule form, used to treat ADD and ADHD, and is the active ingredient in drugs such as Ritalin, Attentin, and Concerta.
    • However, a producer and dealer of illegal steroids obviously wouldn't want to announce their products or its chemical names to anyone catching a glance, so this may explain why Diaz had a common drug name used to label the crates.
