1 vial x 10 ml x 100 mg/ml
What is Testosterone Suspension?
Testosterone Suspension (Test S) is a pure form of testosterone without an ester, making it one of the fastest-acting testosterone variants available. Unlike long or short esters, it delivers immediate effects upon injection, leading to rapid increases in strength, muscle fullness, and performance. Due to its short half-life, frequent injections are necessary to maintain stable blood levels.
Key Benefits
• Rapid muscle and strength gains – Users can experience noticeable improvements within days
• No ester weight – Provides 100% pure testosterone per mg injected
• Enhanced protein synthesis and nitrogen retention – Supports accelerated muscle growth and recovery
• Boosts energy, libido, and motivation – Helps maintain peak performance during training
• Increases red blood cell count – Improves endurance and oxygen delivery to muscles
Dosage and Administration
• Beginner: 25–50 mg per day
• Intermediate: 50–100 mg per day
• Advanced: 100–200 mg per day, often split into 2 daily injections for stable levels
• Injection Frequency: Due to its very short half-life, Test S is typically injected once or twice daily
• Cycle Length: 4–6 weeks is standard, as prolonged use can significantly suppress natural testosterone
Possible Side Effects
• Estrogenic: Gynecomastia, water retention, and bloating due to aromatization into estrogen
• Androgenic: Acne, oily skin, accelerated hair loss, prostate enlargement
• Cardiovascular: Negative impact on cholesterol levels and blood pressure
• Suppression: Natural testosterone production shuts down rapidly, requiring proper PCT
• Injection Site Issues: Due to its water-based suspension, it can cause pain and irritation at the injection site
Precautions
• Use an aromatase inhibitor (AI) such as anastrozole to control estrogen-related side effects
• Monitor mood and behavior changes, as Testosterone Suspension may increase aggression
• Fertility may be temporarily reduced due to suppressed sperm production
• Regular bloodwork is advised to track hormone levels, liver health, and cholesterol during cycle
Stacking
• Bulking: Often combined with Nandrolone, Dianabol, or Anadrol for mass gains
• Cutting: Can be stacked with Winstrol, Trenbolone, or Masteron for lean, hard muscle appearance
• Best used as a pre-workout compound due to its immediate and powerful effect on strength and aggression

Store at room temperature (20°C to 25°C), protected from light and moisture. Shake well before injection to ensure even suspension.
