Parabolan (Trenbolone Hexahydrobenzylcarbonate): Benefits, Cycles & Side Effects

Active substance: Trenbolone hexahydrobenzylcarbonate
Trade names: Parabolan, Danabolan, Trenabol Depot

Parabolan is a rare and powerful form of trenbolone, originally developed by the French pharmaceutical company Negma. Production was discontinued in 1997, and any products claiming to be original Negma Parabolan today are counterfeit. However, modern underground labs continue to manufacture legitimate versions of this compound.

Parabolan is very similar to trenbolone acetate, with the key difference being its longer ester—hexahydrobenzylcarbonate—allowing it to stay active in the body for up to two weeks. This means fewer injections and a more stable release.

Key Benefits of Parabolan

• Rapid lean muscle growth
• Significant strength gains
• No estrogen conversion (no water retention or fat gain)
• Supports fat burning and a dry, shredded look

Unlike many potent anabolic steroids, Parabolan does not aromatize (convert into estrogen), which makes it ideal for athletes seeking a hard, dry physique. It’s frequently compared to Dianabol or Testosterone in anabolic power—minus the bloating and water retention.

Parabolan Side Effects

Despite its benefits, Parabolan can carry some serious side effects, especially if not used correctly. These may include:

• Hair loss (in genetically predisposed users)
• Acne and oily skin
• Increased aggression
• Suppressed natural testosterone production
• Possible erectile dysfunction or low libido (especially without testosterone support)

Although it doesn’t convert to estrogen, Parabolan can stimulate progesterone receptors, which may very rarely result in gynecomastia. To counteract testosterone suppression, a Post Cycle Therapy (PCT) is absolutely necessary after completing a cycle.

Recommended Parabolan Cycles

1. Bulking Cycle

Weeks 1–10:
- Parabolan: 200–300 mg/week (every 5–7 days)
- Testosterone Enanthate: 400–500 mg/week

Weeks 11–14:
- PCT with Nolvadex, Clomid, and/or HCG

This cycle is ideal for clean, quality muscle gains with minimal fluid retention.

2. Cutting Cycle

Weeks 1–8:
- Parabolan: 150–200 mg/week
- Masteron: 300 mg/week
- Testosterone Propionate: 300 mg/week
- (Optional) Winstrol: 50 mg/day during the final 4 weeks

This stack is excellent for preserving lean muscle while shedding body fat, delivering a dry, ripped physique.

Frequently Asked Questions (FAQ)

Is Parabolan suitable for beginners?

No. Due to its potency and potential side effects, Parabolan is recommended for advanced users with prior steroid experience.

How long should a Parabolan cycle last?

Typically between 6 to 10 weeks. Going beyond this increases the risk of severe side effects and hormonal suppression.

How often should I inject Parabolan?

Once every 5–7 days, thanks to its long-acting ester.

Can I use Parabolan without testosterone?

Technically yes, but it is strongly discouraged. Doing so can lead to libido issues and erectile dysfunction due to suppressed natural testosterone.

What should a proper PCT look like after Parabolan?

• Clomid: 50 mg/day for 3–4 weeks
• Nolvadex: 20–40 mg/day for 3–4 weeks
• HCG (optional): 500–1000 IU, 2–3 times per week during the last few weeks of the cycle

Conclusion

Parabolan is a powerful, long-acting trenbolone ester ideal for serious athletes looking to gain lean muscle or cut body fat without water retention. However, it demands respect due to its high androgenic profile and suppression of natural hormones. Use it wisely, always include a testosterone base, and never skip PCT.
