Dihydroboldenone Cypionate 75 by Zhengzhou Pharmaceutical (ZPHC) – Pure Muscle Hardness and Strength

Brand: Zhengzhou Pharmaceutical (ZPHC)

Substance: Dihydroboldenone Cypionate

Action of the Drug

Dihydroboldenone Cypionate, also known as DHB, is one of the most powerful and underrated injectable anabolic steroids. It delivers pure lean muscle gain, dramatic strength increases, and enhanced vascularity without water retention or estrogenic side effects. It binds strongly to the androgen receptor and promotes a dry, hard, and dense look similar to Trenbolone but with better tolerance for many users.

Use in Sports

DHB is favored in strength sports, powerlifting, and contest prep cycles. It helps athletes push through strength plateaus, increase training intensity, and preserve lean mass during calorie deficits. It's ideal for advanced users looking to fine-tune their physique without bloating.

Period of Drug Withdrawal

As a cypionate ester, it has a half-life of about 8–10 days, with full clearance expected 2–3 weeks after the last injection. Weekly injections (2–3 times per week) ensure stable blood levels.

Rate of Suppression of Natural Testosterone Production

DHB significantly suppresses natural testosterone production. Even though it doesn't aromatize, it acts strongly on the HPTA. Exogenous testosterone support is mandatory during any DHB cycle.

What Should Be Used During and After Use

During use: Testosterone Enanthate or Cypionate (300–500 mg/week), aromatase inhibitors are generally not required unless stacking with estrogenic compounds.

After use (PCT): Clomid (50 mg/day) or Nolvadex (20 mg/day) for 4 weeks. HCG (1000 IU every other day for 10 days) may be used before starting PCT to jumpstart natural production.

Combinations in Sports with Other Anabolic and Androgenic Drugs

• Testosterone Enanthate or Cypionate – essential for hormonal base
• Trenbolone Enanthate – extreme strength and lean mass stack (advanced users only)
• Masteron – enhances dryness and visual muscle hardness
• Winstrol – cutting stack focused on vascularity and separation
• Primobolan – mild combination for lean muscle growth
• Equipoise (Boldenone) – longer cycles focused on steady lean gains

Possible Side Effects and How to Avoid Them

DHB doesn't convert to estrogen, so there's no risk of water retention or gynecomastia. However, users may experience increased aggression, tight pumps, night sweats, or injection site irritation. Liver toxicity is low, but injectable site discomfort is common. Keep doses in the 300–500 mg/week range and split injections for better tolerance. Supportive supplements like NAC for general health and fish oil for cardiovascular support are recommended.

Trainer's Recommendation

DHB is one of our go-to compounds for serious lifters who want dense muscle and unmatched strength increases. It's ideal for those already experienced with compounds like Trenbolone but seeking a less suppressive or less harsh alternative. We recommend it for both cutting and lean bulking, depending on diet and stack.

Comparison with Other Drugs

Compared to Trenbolone, DHB provides similar hardness and strength without as many mental or cardiovascular sides. Unlike Boldenone or Nandrolone, it doesn't cause water retention or estrogen-related issues. It's stronger than Masteron in terms of anabolic effect and is a better option than Winstrol for athletes concerned with joint health.
