Syntherol (Synthol) – Cosmetic Muscle Injection Oil

Introduction

Syntherol (commonly known as Synthol) is a cosmetic muscle enhancement oil used by some bodybuilders to artificially increase muscle size. Unlike anabolic steroids, which stimulate muscle growth through protein synthesis, Syntherol simply inflates muscles with oil, creating a larger appearance without functional strength.

Composition

• 85% Medium‑Chain Triglyceride (MCT) oil
• 7.5% Lidocaine (local anesthetic)
• 7.5% Alcohol (preservative)

Key Characteristics

Risks & Side Effects

• Muscle Fibrosis: Permanent scarring of muscle tissue.
• Nerve Damage: Can impair mobility and sensation.
• Infection & Inflammation: Risk of abscesses and tissue necrosis.
• Cardiovascular Risks: Oil embolism can be life‑threatening.
• Permanent Damage: Removal often requires surgery.

Why People Use It

Some bodybuilders use Syntherol as a shortcut to achieve a “bigger” look without years of training. However, the results are often unnatural, disproportionate, and comically obvious, leading to ridicule and long‑term health consequences.

Expert & Public Perspectives

• Medical Experts: Strongly warn against its use due to irreversible damage.
• Bodybuilding Community: Many consider it cheating and unsafe, producing fake‑looking physiques.
• Legal Status: While not banned everywhere, it is not approved by health authorities for any medical or performance use.
