TEST P 100

Generic Name: Testosterone Propionate
Strength & Packaging: 10 mL / 100 mg per mL multidose vial

Reference note: TEST P 100 appears to correspond to testosterone propionate injection 100 mg/mL. I was able to verify testosterone propionate as the generic ingredient and confirm that Health Canada has listed Testosterone Propionate Injection, USP as a multiple-dose vial at 100 mg/mL, but I did not locate a current official monograph for this exact brand name/strength. The draft below is therefore written as a professional ingredient-based catalog description, aligned with current testosterone injection labeling principles.

Product Name & Packaging

TEST P 100 (Testosterone Propionate Injection)
A sterile injectable androgen preparation presented as a 10 mL multidose vial containing 100 mg/mL of testosterone propionate. Testosterone propionate is an esterified form of testosterone used in injectable androgen formulations.

Description

TEST P 100 contains testosterone propionate, a short-acting injectable testosterone ester. In pharmacy and medical-reference style, it may be described as an androgen preparation intended to provide exogenous testosterone in patients for whom testosterone therapy is clinically appropriate and medically supervised.

Indications

Catalog-style indication: for testosterone replacement therapy in males with clinically confirmed deficiency or absence of endogenous testosterone, subject to the prescriber’s judgment and the locally approved labeling for the product being dispensed. Current approved testosterone injection labels require that hypogonadism be confirmed clinically and biochemically before treatment is started.

Dosage & Administration

For intramuscular administration only, under the supervision of a qualified healthcare professional. Current testosterone injection labeling states that injectable testosterone products are not interchangeable on a milligram-per-milligram basis, and diagnosis should be confirmed using morning testosterone measurements on at least two separate days before therapy begins. Because I did not locate a current official monograph for this exact TEST P 100 brand, the dose and dosing interval should follow the prescribing clinician’s instructions and the approved local product label.

Mechanism of Action

Testosterone acts by replacing testosterone that is normally produced by the body. As an androgen, it supports the development and maintenance of male sexual characteristics and related physiologic functions when used for medically confirmed testosterone deficiency.

Precautions

Use only with appropriate medical supervision. Testosterone therapy is generally contraindicated or requires special caution in patients with known or suspected prostate cancer, male breast cancer, pregnancy exposure risk, polycythemia, cardiovascular risk factors, or a history of abuse/misuse of anabolic-androgenic steroids. Current testosterone labeling also warns that testosterone products can raise blood pressure and require ongoing clinical and laboratory monitoring.

Side Effects

Potential adverse effects reported across testosterone injection labeling include injection-site reactions, acne or oily skin, gynecomastia, headache, mood changes, polycythemia, fluid retention/edema, and suppression of spermatogenesis or oligospermia, particularly with higher exposure. Serious cardiovascular adverse events have also been reported with androgen products.

Storage

In the absence of a located product-specific monograph for this exact brand, a conservative professional storage statement aligned with current testosterone injection labeling is: store at 20°C to 25°C (68°F to 77°F), protect from light, and keep in a secure location out of reach of children. Current testosterone injection labels also note that if crystals form at lower-than-recommended temperatures, warming the vial may help re-dissolve them.
