What is site enhancement oil?

Site enhancement oil (SEO) is a substance some bodybuilders use to artificially increase the size of their muscles by injecting it directly into the muscle. John Meadows explains that this oil swells the muscle up, giving the appearance of larger muscles without the hard work typically required to achieve that size. Initially, a form of SEO called "acycline" was used, which was an inflammatory agent that temporarily increased muscle size and preserved muscle quality and detail.

Meadows also mentions "synthol," a type of SEO containing silicone that was more commonly known for creating exaggerated muscle sizes. This practice, often highlighted in bodybuilding magazines, misled many into believing that achieving such physiques was solely due to workout routines rather than injections of these oils 1.
