Synthol is a substance used by body builders as a temporary implant which is injected deeply into the muscle. The enlargement effects are immediate. Synthol is used in small groups of muscles to enlarge their volume (for example triceps, biceps, deltoids, muscles of the calf). People with body dysmorphia often abuse it unnaturally in place of actually working out. #bodydysphormia #synthol #bodybuilding #gymlife #doctor | Mary Johnson
