Description

(Dual-Ester Testosterone Therapy for Hormone Replacement and Performance Optimization)

Sustained-Release Androgen Therapy for Stable Hormonal Balance and Male Vitality

This Testosterone Cypionate/Enanthate injectable formulation delivers a blend of two long-acting testosterone esters, compounded at 100 mg/mL in a 5 mL sterile vial. Designed for intramuscular administration, this compound provides steady, predictable serum testosterone levels to support testosterone replacement therapy (TRT) in men with clinical hypogonadism, low testosterone symptoms, or hormone decline due to aging.

The combination of testosterone cypionate and testosterone enanthate offers a balanced pharmacokinetic profile, improving symptom relief and injection flexibility while minimizing hormonal peaks and troughs often associated with single-ester protocols.

Product Overview

• Active Ingredients: Testosterone Cypionate and Testosterone Enanthate

• Concentration: 100 mg/mL (combined total)

• Volume: 5 mL per vial (total 500 mg testosterone per vial)

• Route: Intramuscular injection (IM), typically in the gluteal or thigh muscle

• Form: Oil-based, sterile compounded solution

• Administration Schedule: Once every 3–7 days depending on patient response

• Storage: Room temperature (20–25°C); protect from light

• Availability: Prescription only; compounded under sterile pharmacy standards

What Is Testosterone Cypionate/Enanthate?

Both testosterone cypionate and testosterone enanthate are slow-release testosterone esters, commonly used in hormone replacement therapy due to their favorable absorption and metabolic profiles. When combined:

• Testosterone Cypionate provides a slightly longer half-life (~8 days), sustaining serum levels over a week

• Testosterone Enanthate has a half-life of 4.5–5 days, allowing for quicker initial peak and a smooth decline

• Together, they offer a more even testosterone curve with less volatility and improved symptom management

This dual-ester blend is particularly beneficial for patients needing stable, sustained androgen support without the extremes of shorter or ultra-long-acting formulations.

Clinical Applications

This compounded injection is used to treat:

1. Primary or Secondary Hypogonadism

• Diagnosed by low serum testosterone (<300 ng/dL) and symptoms such as:
  • Low libido

  • Erectile dysfunction

  • Fatigue or poor motivation

  • Muscle loss and increased fat

  • Brain fog or depressed mood

2. Age-Related Androgen Decline

• Men in their 40s and beyond experiencing gradual hormonal insufficiency

• Often part of a broader male hormone optimization program

3. Athletic and Metabolic Support (Supervised Use Only)

• Support for muscle recovery, energy levels, and body composition under physician-monitored protocols

Mechanism of Action

Exogenous testosterone supplementation increases serum androgen levels, restoring physiological function in testosterone-deficient individuals. Benefits include:

• Enhanced libido and sexual performance

• Improved lean muscle mass and metabolic rate

• Increased energy, confidence, and cognitive clarity

• Stabilized mood and motivation

• Improved bone mineral density and cardiovascular markers

The oil-based dual-ester formulation ensures slow, steady hormone release for better symptom consistency and reduced injection frequency.

Dosing and Administration

• Initial Dose: 100–200 mg per week, divided into 1–2 injections

• Typical Maintenance: 0.5–1 mL (50–100 mg) once or twice weekly, based on labs and symptom response

• Injection Site: Deep IM injection into gluteal or vastus lateralis muscle

• Supplies Needed: 23–25G needle, 1″–1.5″ length for IM delivery; alcohol swab, sterile syringe

• Monitoring: Baseline and follow-up labs to evaluate testosterone, estradiol, hematocrit, and PSA

Titration may be required to balance symptom relief with safety indicators.

Safety and Tolerability

Testosterone therapy is generally safe and effective when properly prescribed and monitored.

Common, reversible side effects may include:

• Mild injection site soreness

• Acne or skin oiliness

• Increased hematocrit

• Fluid retention

• Mood changes

Rare but serious concerns (monitoring required):

• Erythrocytosis

• Elevated PSA or prostate symptoms

• Estrogen-related side effects (gynecomastia, water retention)

• Lipid profile changes

May require aromatase inhibitor co-therapy in high aromatizers.

Contraindications

Do not use in patients with:

• Prostate or breast cancer (male)

• Uncontrolled heart failure or severe renal disease

• Elevated hematocrit (>54%)

• Untreated severe sleep apnea

• Known hypersensitivity to testosterone esters or carrier oil

Storage & Handling

• Store at room temperature (68–77°F)

• Protect from light and extreme heat

• Use a sterile technique when drawing each dose

• Do not reuse needles; single-patient use only

Why Choose This Dual-Ester Formulation?

• Smoother hormonal profile than single-ester injections

• Reduces hormonal “crashes” between injections

• Flexible scheduling (1–2x/week)

• Ideal for patients who are sensitive to rapid peaks or dips

• Custom-compounded for purity, sterility, and consistent performance

Summary

Testosterone Cypionate/Enanthate Injection – 100 mg/mL (5 mL) offers a dual-ester testosterone therapy designed for stable, long-acting symptom control in male hormone replacement. By combining the two most widely used esters, this formulation promotes sustained energy, libido, muscle strength, and mental clarity—supporting total male wellness with fewer hormonal fluctuations. Professionally compounded for clinical precision and backed by therapeutic outcomes, it’s a preferred option in modern testosterone optimization therapy.
