Why Does Trenbolone Cause “Tren Cough”
Trenbolone-induced coughing, or “tren cough,” is a sudden, intense bout of coughing that occurs shortly after an injection of Trenbolone. This effect is not unique to Tren but is more commonly associated with it due to its strong irritant properties.
Mechanism Behind Tren Cough
Solvent and Carrier Irritation
Many Trenbolone preparations use volatile solvents (like benzyl alcohol or benzyl benzoate), which can irritate lung tissue if they enter systemic circulation rapidly.
Prostaglandin Release
Trenbolone is known to increase prostaglandin production, especially PGF2α, a compound that stimulates smooth muscle contraction in the lungs, leading to bronchoconstriction and coughing.
Micro-Oil Embolism
If a small amount of oil enters a capillary, it can reach the lungs, causing an embolic reaction. This leads to temporary hypoxia and triggers a cough reflex.
Histamine and Mast Cell Activation
Some users experience mild allergic-like reactions due to histamine release, which can lead to bronchospasms and coughing.

How Salbutamol (Albuterol) Helps Prevent Tren Cough
Salbutamol is a β2-adrenergic receptor agonist commonly used for asthma and bronchospasms. It can help prevent tren cough by:
Relaxing Bronchial Muscles → Reducing the intensity of cough-inducing spasms.
Inhibiting Prostaglandin Effects → Counteracting PGF2α-induced constriction.
Opening Airways → Preventing severe constriction in those prone to bronchospasms.
