Description

Boldenone Undecylenate ZPHC 250 mg/ml (10 × 1 ml Ampoules)

Boldenone Undecylenate from ZPHC is a long-acting injectable anabolic steroid commonly used in bodybuilding and strength sports for gradual, steady muscle gain and improved physical performance. It is a testosterone-derived compound with a modified structure that reduces androgenic effects while maintaining anabolic activity.

Because of its long undecylenate ester, it releases slowly into the body, producing stable and sustained effects over time. It is often chosen for cycles focused on lean mass development with minimal water retention.

Steroid Profile

Anabolic activity: 100% of testosterone
Androgenic activity: 50% of testosterone
Aromatization: low
Liver toxicity: low (injectable form)
Half-life: ~14 days
Detection time: up to 5 months

Key Characteristics

Boldenone Undecylenate provides slow but steady improvements in muscle mass and performance. It is known for producing “clean” gains with relatively low estrogen-related effects compared to many other anabolic compounds.

Effects and Benefits

• Gradual increase in lean muscle mass
• Low water retention during gains
• Improved appetite, supporting bulking phases
• Enhanced red blood cell production and oxygen delivery
• Improved endurance and training capacity
• Better muscle fullness and vascularity over time

Advantages of ZPHC Ampoules

• Pre-measured dosing (250 mg/ml)
• Sterile single-use ampoules

General Use Information

Typical performance-related use:

• 400–600 mg per week (men)
• 8–12 week cycle duration
• Often combined with testosterone-based compounds to support hormonal balance

Because of its long half-life, effects build gradually and remain stable even with less frequent injections.

Common Combinations

• Testosterone enanthate or cypionate for mass cycles
• Stanozolol or Masteron for cutting-focused cycles
• Other anabolic agents depending on goal (mass vs recomposition)

Benefits in Training Context

• Steady, quality muscle gains
• Improved endurance and oxygen efficiency
• Better appetite for bulking phases
• Lower incidence of estrogen-related side effects compared to stronger aromatizing compounds

 Side Effects

• Suppression of natural testosterone production
• Acne and oily skin
• Hair loss in genetically predisposed users
• Mild estrogenic effects in some cases
• Increased hematocrit (thicker blood)
• Blood pressure and cholesterol changes
• Mood or energy fluctuations
