Boldenone Undecylenate 500 by Zhengzhou Pharmaceutical (ZPHC) – Long-Lasting Lean Muscle Growth

Brand: Zhengzhou Pharmaceutical (ZPHC)

Substance: Boldenone Undecylenate

Action of the Drug

Boldenone Undecylenate, commonly known as Equipoise, is a slow-acting injectable anabolic steroid derived from testosterone. It promotes stable lean muscle growth, improved appetite, increased red blood cell production, and steady strength gains with minimal water retention. With a balanced anabolic-to-androgenic ratio, it's well-tolerated and ideal for longer cycles.

Use in Sports

Bodybuilders and strength athletes use Boldenone to build quality muscle mass and enhance endurance. It's especially popular during lean bulking phases and recomposition cycles. Its slow release ensures consistent performance and fewer injections throughout the week.

Period of Drug Withdrawal

Boldenone has a long half-life of 14–16 days. Full withdrawal and clearance may take 4–6 weeks. This must be considered when planning PCT and drug testing windows.

Rate of Suppression of Natural Testosterone Production

Moderate suppression occurs, especially during extended cycles. Exogenous testosterone is strongly recommended throughout the entire cycle to maintain hormonal balance and prevent sexual dysfunction or lethargy.

What Should Be Used During and After Use

During use: Testosterone Enanthate or Cypionate (300–500 mg/week). Aromatase inhibitors like Arimidex (0.5 mg EOD) may be used if estrogenic symptoms appear, though Boldenone aromatizes at a very low rate.

After use (PCT): Clomid (50 mg/day) or Nolvadex (20 mg/day) for 4–6 weeks. HCG (1000 IU every other day for 10 days) may be added prior to PCT if cycle exceeded 10–12 weeks.

Combinations in Sports with Other Anabolic and Androgenic Drugs

• Testosterone Enanthate – base hormone for all stacks
• Dianabol – kickstart for mass gains in first 4 weeks
• Trenbolone Enanthate – advanced lean mass and strength combo
• Primobolan – clean bulking and body recomposition
• Anavar – enhances fat loss and muscle preservation
• Masteron – promotes harder, drier physique
• Winstrol – for cutting and increased vascularity

Possible Side Effects and How to Avoid Them

Boldenone has low estrogenic activity, so water retention and gynecomastia are rare. Side effects may include increased appetite, mild acne, and elevated blood pressure or RBC levels. Routine blood work is advised. Keep cycle length at 10–12 weeks to avoid overaccumulation of red blood cells. Use liver and cardiovascular support like NAC, omega-3s, and regular cardio activity.

Trainer's Recommendation

We often recommend Boldenone to intermediate athletes looking for slow, clean, and long-term gains. It's ideal for those who want steady strength and muscle growth without puffiness or harsh sides. It's also a great bridge between beginner and advanced steroid cycles due to its smooth and controllable profile.

Comparison with Other Drugs

Compared to Deca-Durabolin, Boldenone doesn't cause as much water retention or libido suppression. It's less suppressive than Trenbolone and has fewer psychological sides. Unlike Anadrol or Dianabol, gains are lean and maintainable post-cycle. It's more anabolic than Primobolan and better suited for mass cycles than Masteron or Winstrol.
