The cute guy above looks like he is at an early stage of Bigorexia. Some guys go on to do major damage.

Bigorexia or muscle dysmorphia is a disorder in which a person becomes obsessed with the idea that he or she is not muscular enough.

Muscle dysmorphia can cause mostly guys, but some women to:
Constantly examine themselves in a mirror
Frequently compare themselves with others
Hate their reflections
Become distressed if they miss a workout session or one of their many meals a day
Become distressed if they do not receive enough protein per day in their diet
Take potentially dangerous anabolic steroids
Neglect jobs, relationships, or family because of excessive exercising
Have delusions of being underweight or below average in musculature.
In extreme cases, inject appendages with fluid (e.g. Synthol)

A Site Enhancement Oil (SEO) is a liquid substance, usually a mixture of oils, used by some bodybuilders to increase the apparent size of some muscles. The effects of SEOs are purely and solely cosmetic and there is no increase in muscular performance.
SEOs work by filling the muscle up with an oil substance. It is site-injected, that is, it is injected directly into the muscle whose size is to be increased. SEO is usually used to ‘top up’ a muscle that is not quite up to standard with the rest of the body.
One of the more popular SEOs is Synthol, which was developed in the early 1990s by the German bodybuilder Christopher T. Clark as a replacement for Esiclene which went out of production at the time. Synthol consists of 85 % medium-chain triglycerides, 7.5 % Lidocaine and 7.5 % Benzyl alcohol.
A site enhancement oil is not an androgen and contains no steroids.
