**FULL PRESCRIBING INFORMATION**

**1 INDICATIONS AND USAGE**
TESTOMED PROP 100 is indicated for investigational use in adults to promote rapid muscle and strength gains, enhance libido, improve energy and mood, increase red blood cell production, support recovery, and provide short-term hormone boosts. It is commonly used in cutting cycles or as a kickstarter for rapid effects. This product is not approved for any medical condition and should be used under medical supervision.

**2 DOSAGE AND ADMINISTRATION**
**2.1 Recommended Dosage**
Administer TESTOMED PROP 100 by deep intramuscular injection into the gluteal muscle or other large muscle groups, preferably every other day due to short half-life. Rotate injection sites to minimize irritation.
– Males: 100 mg to 300 mg weekly, divided into three or more doses (e.g., 100 mg every other day).
– Females: 25 mg to 50 mg weekly, divided into three or more doses to minimize virilization risk.
Adjust dosage based on response and tolerance. Discontinue if adverse effects occur.

**2.2 Preparation and Handling**
Inspect vial for particulate matter or discoloration before use. Use sterile technique for administration.

**3 DOSAGE FORMS AND STRENGTHS**
TESTOMED PROP 100 is supplied as a sterile solution containing 100 mg testosterone propionate per mL in 10 mL multi-dose vials.

**4 CONTRAINDICATIONS**
TESTOMED PROP 100 is contraindicated in:
– Patients with known or suspected prostate or breast carcinoma.
– Pregnant women (Category X).
– Patients with hypersensitivity to testosterone propionate, ethyl oleate, ricinus oil, or other excipients.
– Patients with severe cardiac, hepatic, or renal insufficiency.

**5 WARNINGS AND PRECAUTIONS**
**5.1 Cardiovascular Effects**
May alter serum lipid profiles, increasing LDL and decreasing HDL, raising the risk of atherosclerosis. Monitor cholesterol levels periodically during treatment.
**5.2 Hepatotoxicity**
May cause elevated liver enzymes or, rarely, peliosis hepatis. Perform liver function tests before and during therapy; discontinue if jaundice or abnormal tests occur.
**5.3 Androgenic Effects**
Females may experience virilization, including deepening of voice, hirsutism, or clitoromegaly, which may be irreversible. Discontinue immediately if signs of virilization appear.
**5.4 Endocrine Effects**
Suppresses hypothalamic-pituitary-gonadal axis, reducing natural testosterone production. Implement post-cycle therapy to restore hormonal balance.
**5.5 Injection Site Reactions**
Ethyl oleate and ricinus oil may cause localized pain, redness, or swelling at the injection site, particularly with frequent dosing. Rotate injection sites and monitor for signs of infection or abscess.

**6 ADVERSE REACTIONS**
Reported adverse reactions include:
– Dermatologic: Acne, oily skin, male pattern baldness in predisposed individuals.
– Psychiatric: Aggression, irritability, mood swings.
– Endocrine: Gynecomastia, testicular atrophy, reduced fertility.
– Cardiovascular: Hypertension, altered lipid profiles.
– Hepatic: Elevated AST/ALT, jaundice (rare).
– Local: Injection site pain, erythema, or abscess (rare).

**7 DRUG INTERACTIONS**
**7.1 Anticoagulants**
May increase bleeding risk with warfarin or other anticoagulants; monitor INR or prothrombin time closely.
**7.2 Hypoglycemic Agents**
May alter blood glucose levels, potentially requiring adjustment of insulin or oral antidiabetic doses; monitor closely.
**7.3 Corticosteroids**
Concurrent use may increase risk of edema, particularly in patients with cardiac or renal conditions.

**8 USE IN SPECIFIC POPULATIONS**
**8.1 Pregnancy**
Category X: May cause fetal harm, including virilization of a female fetus. Contraindicated in pregnant women.
**8.2 Lactation**
Excretion in breast milk is unknown; breastfeeding is not recommended due to potential risks to the infant.
**8.4 Pediatric Use**
Not recommended; may cause premature epiphyseal closure, leading to stunted growth.
**8.5 Geriatric Use**
Increased risk of prostatic hypertrophy or carcinoma; monitor prostate health closely during use.

**9 DRUG ABUSE AND DEPENDENCE**
Controlled substance in some jurisdictions. Potential for misuse leading to physical or psychological dependence, particularly with prolonged use or high doses.

**10 OVERDOSAGE**
Symptoms of overdose may include severe androgenic effects, such as aggression, acne exacerbation, or hypertension. No specific antidote exists; treat symptomatically and discontinue use immediately.

**12 CLINICAL PHARMACOLOGY**
**12.1 Mechanism of Action**
Testosterone propionate binds to androgen receptors, promoting protein synthesis, nitrogen retention, and red blood cell production for rapid muscle growth and recovery.
**12.3 Pharmacokinetics**
Absorbed rapidly after intramuscular injection; peak plasma levels in 1-2 days; half-life approximately 2 days; metabolized in the liver; excreted primarily in urine.

**13 NONCLINICAL TOXICOLOGY**
Animal studies indicate potential carcinogenicity, including hepatic and prostate tumors; no human data available.

**16 HOW SUPPLIED/STORAGE AND HANDLING**
