Looking for a serious edge before hitting the gym? Not just a stim-packed powder—but a real anabolic kick that turns training into an assault on your limits? U4 is exactly that: an ultra-potent injectable pre-workout steroid stack engineered for advanced users who want immediate strength, power, and results.
What is U4?
U4 combines four high-impact compounds at 25 mg/mL each into one seamless formula. Each ingredient serves a specific purpose, creating a synergy that delivers fast, hard, and noticeable effects within hours of injection.
U4 Composition (per mL):
- 25 mg Testosterone (no ester)
- 25 mg Trenbolone (no ester)
- 25 mg Turinabol (injectable Tbol)
- 25 mg Anadrol (injectable Oxymetholone)
No esters = no delay. You inject, you train, and you feel it fast.
🔬 Four Agents. Four Mechanisms. One Brutal Anabolic Surge.
🧨 Testosterone (no ester)
The base hormone of all cycles, now in its fastest form. Testosterone without ester hits the bloodstream rapidly, elevating free testosterone levels and priming the body for growth. It supports strength, recovery, and mental drive—all essential during intense training.
🔥 Trenbolone (no ester)
Known for delivering raw aggression and strength, Trenbolone is one of the most powerful anabolic steroids ever developed. In esterless form, its impact is immediate. This compound amplifies nitrogen retention, boosts red blood cells, and enhances muscular density—without aromatization.
⚙️ Turinabol (injectable)
Tbol is a dry, DHT-derived compound that increases lean mass without bloating or estrogen-related sides. It improves muscle definition, hardness, and endurance. As an injectable, it avoids liver strain and offers greater bioavailability than the oral form.
💥 Anadrol (Oxymetholone)
Anadrol adds explosive mass, pumps, and stamina. Though not a strong AR binder, it stimulates growth through unique non-receptor pathways. In its injectable format, it delivers smoother results with less liver burden than its oral version.
📈 Why U4 Works Differently Than Most Steroid Blends
What separates U4 from a standard cycle isn’t just the speed—it’s the combination logic:
- Testosterone & Trenbolone act fast via androgen receptor binding
- Turinabol enhances dry gains and frees up other hormones by reducing SHBG
- Anadrol boosts muscle-building through alternate pathways, rounding out the anabolic response
The result? You’re hitting the muscle-building process from multiple angles, with a rapid onset and peak intensity right when you need it: pre-workout.
💉 How to Use U4
U4 is meant to be taken 2–3 hours before training.
Start with 0.5 mL to gauge your response. Most experienced users go with 1 to 1.5 mL per session.
Injection is smooth, with a well-formulated carrier oil. It can be used on non-training days at a lower dose (0.25–0.5 mL) to maintain steady anabolic levels.
🔁 Stacking Options
- Bulking? Add long-ester Testosterone, Nandrolone, or Boldenone
- Cutting? Combine with Masteron or use solo as a hardening pre-workout agent
- Contest prep? Use as a final-week power surge to preserve mass, fullness, and performance
🧠 Final Word: U4 Isn’t a Beginner’s Tool—It’s a Weapon
If you’re looking for something subtle, U4 isn’t it. This is a full-spectrum pre-workout anabolic solution designed for fast impact, no fluff. Each compound is chosen for its immediate effect, not for comfort or convenience.
Experienced athletes, competitive bodybuilders, and strength-driven lifters will appreciate the unfiltered power of U4.
When you’re ready to train with intensity that demands results—Sciroxx U4 delivers.
