SP Parabolan

SP Parabolan is an illicit anabolic-androgenic steroid (AAS) made by the underground lab SP Laboratories. The active ingredient is trenbolone hexahydrobenzylcarbonate, the same compound once used in a legitimate human-grade drug called Parabolan. Today, products like SP Parabolan are not medically regulated or approved and are sold on the black market for illicit physique and performance enhancement.

• What it is: Trenbolone hexahydrobenzylcarbonate is a potent synthetic steroid that is far more powerful than testosterone.
• History: A human-grade version of this compound was manufactured by a French pharmaceutical company but has since been discontinued.
• Action: As an AAS, it binds to androgen receptors to increase protein synthesis in muscles and bones, leading to significant increases in muscle mass and strength. The hexahydrobenzylcarbonate ester is designed for a long half-life, meaning it has a slow release and requires less frequent injections than other forms of trenbolone.

• Potent muscle gains: Users can experience rapid and dramatic increases in muscle mass and strength.
• Enhanced performance: Trenbolone is known for its ability to improve muscle recovery and nutrient utilization.
• Does not aromatize: Unlike many other steroids, trenbolone does not convert into estrogen. This reduces the risk of estrogenic side effects, such as water retention and gynecomastia (enlarged male breasts).
• “Hard” physique: Because of its non-aromatizing nature, trenbolone is popular during cutting phases to help create a hard, lean, and defined physique.

• “Tren cough”: A unique and violent coughing fit that can occur shortly after an injection. It is thought to be caused by the oil solution triggering prostaglandins when it enters the bloodstream.
• Cardiovascular strain: Trenbolone can cause high blood pressure, unhealthy cholesterol changes, and increase the risk of heart attacks.
• Severe hormonal suppression: Use of trenbolone leads to the profound suppression of natural testosterone production, often requiring post-cycle therapy (PCT) to recover.
• Mental and emotional side effects: Many users report mood swings, anxiety, paranoia, aggression (“roid rage”), and sleep disturbances (“trensomnia”).
• Androgenic side effects: Common side effects include severe acne, oily skin, and accelerated male-pattern baldness.
• Liver and kidney issues: Long-term use can negatively impact liver and kidney health.
• Unknown quality: As an underground product, there is no guarantee of SP Parabolan’s purity, dosage, or sterility, which can introduce contaminants and further health complications
