Testosterone Propionate (T-PRO), formulated for intramuscular injection, comprises Testosterone Propionate, an oil-soluble derivative of the androgenic hormone testosterone. Attached to a short ester, Testosterone Propionate offers a higher concentration of testosterone per dosage compared to other ester-based testosterone preparations. For instance, 100mg of Testosterone Propionate contains 83.72mg of testosterone, making it a potent option for hormone replacement therapy.

In males, Testosterone Propionate is prescribed to address primary hypogonadism resulting from conditions such as congenital or acquired testicular failure, cryptorchidism, bilateral torsion, orchitis, vanishing testis syndrome, or orchiectomy. It's important to note that Testosterone Propionate undergoes conversion into estrogen and dihydrotestosterone (DHT), necessitating the use of a reliable anti-estrogen medication alongside this compound to manage potential side effects.

Packaging: Single vial with silicone stopper, containing 10ml of product.
