What is Parabolan (Trenbolone Hexahydrobenzylcarbonate)?

Parabolan is a long-acting form of trenbolone, one of the most powerful anabolic steroids ever made. It was originally developed in France as a human-use medicine before being discontinued. Today it's used by experienced bodybuilders who want serious gains in muscle and strength without holding excess water.

Quick Facts

How Does It Work?

Trenbolone binds very strongly to androgen receptors in muscle tissue, driving protein synthesis and nitrogen retention much harder than testosterone. It also raises IGF-1 levels and reduces glucocorticoid hormones like cortisol, which would otherwise break down muscle. The hexahydrobenzylcarbonate ester releases the compound slowly, so injections are only needed once or twice a week.

What It's Used For

• Building lean, hard muscle mass
• Cutting cycles — preserving muscle while losing body fat
• Increasing strength and overall physical performance

What to Expect

Users typically see dense, dry muscle gains with very little water retention. Strength increases can come on quickly, often within the first two weeks. Body composition tends to improve noticeably even without major changes to diet.

Possible Side Effects

• Night sweats and increased body temperature
• Androgenic effects — hair loss, acne, increased body hair
• Suppression of natural testosterone production
• Raised blood pressure and cardiovascular strain
• Mood changes, aggression, or anxiety in some users

Cycle & Dosage Notes

Cycles typically run 8–12 weeks at 150–300mg per week, injected once or twice weekly due to the long ester. PCT is essential after the cycle, usually starting 2–3 weeks after the last injection. Parabolan is often stacked with testosterone to offset natural suppression, and pairs well with compounds like Masteron or Anavar during a cut.

Storage

Keep at room temperature (15–25°C), away from light and moisture. Leave in the original packaging.
