Boldenone Undecylenate 250 by Zhengzhou Pharmaceutical (ZPHC) – Steady Lean Gains with Minimal Estrogenic Activity

Brand: Zhengzhou Pharmaceutical (ZPHC)

Substance: Boldenone Undecylenate

Action of the Drug

Boldenone Undecylenate 250, also known as Equipoise, is a long-acting injectable anabolic steroid derived from testosterone. It provides a steady release that supports gradual lean muscle growth, increased strength, improved vascularity, and appetite stimulation without excessive water retention. Its moderate anabolic profile makes it ideal for extended use with fewer side effects.

Use in Sports

Used widely in bodybuilding and strength sports, Boldenone is favored during lean bulking cycles and recomposition phases. It boosts muscular endurance and quality mass without bloat, making it a go-to for athletes who need long-term, sustainable growth.

Period of Drug Withdrawal

Boldenone Undecylenate has a half-life of approximately 14–16 days, which means full clearance from the body may take 4–6 weeks after the last injection. Athletes should time PCT and drug-tested events accordingly.

Rate of Suppression of Natural Testosterone Production

Moderate suppression occurs, especially over cycles longer than 8–10 weeks. A testosterone base should always be included to maintain libido, mood, and overall well-being.

What Should Be Used During and After Use

During use: Testosterone Enanthate or Cypionate (300–500 mg/week), and if needed, Arimidex (0.5 mg every other day) to control estrogen levels.

After use (PCT): Clomid (50 mg/day) or Nolvadex (20 mg/day) for 4–6 weeks. Add HCG (1000 IU EOD for 10 days) before starting PCT if the cycle lasts more than 10 weeks.

Combinations in Sports with Other Anabolic and Androgenic Drugs

• Testosterone Enanthate – to maintain hormonal balance
• Dianabol – for early cycle mass gain acceleration
• Trenbolone Enanthate – for strength and hard lean mass
• Primobolan – supports clean muscle gains with minimal fat
• Anavar – boosts cutting cycles and vascularity
• Masteron – helps create a dry, aesthetic physique
• Winstrol – enhances hardness and definition during a cut

Possible Side Effects and How to Avoid Them

Boldenone aromatizes at a low rate, so estrogenic side effects like gynecomastia and water retention are uncommon. Potential issues include increased red blood cell count, mild acne, and elevated blood pressure. These can be managed with proper dosage, regular blood work, hydration, and cardiovascular support supplements like omega-3, taurine, and NAC.

Trainer's Recommendation

We recommend Boldenone Undecylenate 250 to intermediate users looking for slow and clean gains over a longer period. It's excellent for bridging cycles and offers quality results without the harsh sides of stronger compounds. Ideal for those focused on endurance, muscle maturity, and a drier physique over time.

Comparison with Other Drugs

Compared to Deca-Durabolin, Boldenone causes less water retention and is friendlier to libido. It's less androgenic than Trenbolone and offers more stable progress. Unlike Dianabol or Anadrol, gains are lean and sustainable post-cycle. It's a stronger bulking agent than Primobolan, yet gentler than Tren or Superdrol.

Main Properties

• Drying – Fat Loss: Supports fat metabolism and muscle retention during cuts.
