Trendione Review: My First-Hand Experience With This Powerful Prohormone

Over the past decade, I’ve tested dozens of muscle-building supplements—from basic creatine to complex prohormones. When I decided to try Trendione (also known as Trenavar), I knew I was stepping into advanced territory. This potent compound promises trenbolone-like effects without actually being trenbolone itself, and after an 8-week cycle, I have some strong opinions about it.

What Is Trendione?

Trendione (Estra-4,9,11-triene-3,17-dione) is a prohormone that converts to trenbolone in your body after ingestion. Each capsule contains 30mg of the active compound, along with standard inactive ingredients like microcrystalline cellulose, magnesium stearate, and silicon dioxide in a gelatin capsule.

Unlike many supplements that hide behind proprietary blends, Trendione is straightforward—you know exactly what you’re getting. The recommended dosage is 1-2 capsules daily with meals, not exceeding 3 capsules total.

My 8-Week Trendione Experience

I started with 1 capsule daily for the first week to assess tolerance, then moved to 2 capsules daily for the remaining 7 weeks. Here’s what happened:

Weeks 1-2: The Initial Effects

Within days, I noticed increased vascularity and a subtle hardening effect in my muscles. My strength went up about 5-10% across all lifts, which was impressive for such a short timeframe. However, I also experienced some insomnia and night sweats—classic trenbolone-related side effects that told me this stuff was definitely working.

Weeks 3-5: Peak Performance

This is when Trendione really shined. My body composition changed noticeably—I gained 7 pounds while actually losing fat. Veins I’d never seen before appeared across my shoulders and arms. My strength continued climbing, with my bench press increasing by 25 pounds and deadlift by 40 pounds.

The muscle hardness was unmistakable. When I flexed, my muscles felt dense and solid in a way that’s hard to achieve naturally. Recovery between workouts was also enhanced—I could train harder with less soreness the next day.

Weeks 6-8: Diminishing Returns and Side Effects

The gains continued but slowed down during the final weeks. By the end of week 8, I had gained a total of 11 pounds of what appeared to be mostly lean mass. My strength gains plateaued around week 6.

Unfortunately, this is also when the side effects became more pronounced. My blood pressure increased by about 15 points systolic. I experienced significant aggression and mood swings—something my training partners noticed before I did. Night sweats became worse, and my sleep quality decreased substantially.

The Results: What I Gained

• 11 pounds of mostly lean mass
• Significant strength increases (roughly 15-20% across major lifts)
• Noticeable fat loss while building muscle
• Enhanced vascularity and muscle hardness
• Faster recovery between workouts

The Downsides: Real Talk About Side Effects

I won’t sugarcoat this—Trendione isn’t mild. Here’s what I experienced:

• Elevated blood pressure (monitored weekly)
• Increased aggression and irritability
• Night sweats and insomnia
• Some hair shedding (I’m genetically predisposed)
• Suppressed natural testosterone (confirmed by post-cycle bloodwork)
• Elevated liver enzymes (I used liver support supplements throughout)

The hormonal suppression was significant enough that post-cycle therapy (PCT) was absolutely necessary. I used a combination of Nolvadex and Clomid for 4 weeks after my cycle to help restore natural testosterone production.

Who Should Consider Trendione?

This is not a beginner supplement. If you’ve never used prohormones before, Trendione is not where you should start. Based on my experience, I would only recommend Trendione to:

• Experienced lifters who have used other prohormones successfully
• Men over 25 who understand hormonal suppression risks
• People willing to invest in proper cycle support and PCT
• Those who can commit to regular blood work and health monitoring

Who Should Avoid Trendione?

You should absolutely avoid this supplement if you:

• Are under 21 years old
• Have any existing health conditions (especially liver, heart, or hormone-related)
• Are a competitive athlete (it will trigger positive drug tests)
• Are new to resistance training or supplementation
• Are unwilling to conduct proper post-cycle therapy
• Are female (serious virilization risks)

On-Cycle Support: Essential, Not Optional

If you decide to try Trendione, these support supplements aren’t optional—they’re mandatory:

• Liver support: I used NAC (1000mg daily) and milk thistle (500mg daily)
• Blood pressure support: Hawthorn berry and CoQ10 helped manage mine
• Lipid support: Omega-3s (3-5g daily) and citrus bergamot

My Overall Rating: 3.5/5

Trendione delivers impressive results but comes with serious side effects and health considerations. The 3.5/5 rating breaks down like this:

• Effectiveness for muscle gains: 5/5
• Strength improvements: 4.5/5
• Fat loss effects: 4/5
• Side effect profile: 2/5
• Safety concerns: 2/5
• Value for money: 4/5

Final Thoughts

Trendione works—there’s no denying that. The muscle and strength gains I experienced were some of the most dramatic I’ve seen from any legal supplement. But these results come at a price that extends beyond the dollar cost.

The side effects are real and potentially dangerous if you’re not prepared to manage them. The hormonal suppression means that proper PCT isn’t just recommended—it’s essential. And the potential impact on cardiovascular health shouldn’t be overlooked.

If you’re looking for dramatic results and understand the risks, Trendione delivers. But for most people, the risk-to-reward ratio simply doesn’t make sense when safer (albeit less effective) alternatives exist.

Remember, no supplement is worth compromising your long-term health. Whatever you decide, prioritize safety, do your health monitoring, and never skip proper support supplements and PCT.

Safety Considerations

Trendione users should limit cycles to 8 weeks maximum due to its potent anabolic effects on the body. Regular post-cycle therapy protocols remain essential after using this compound to maintain natural hormone production.

Performance Ratings

Muscle Growth: 4.5/5

Trendione excels at promoting lean muscle tissue development through increased protein synthesis. Visible mass gains typically occur within 3-4 weeks of consistent use alongside proper nutrition. Alternative options: Metribolone, Methylstenbolone.

Strength Gains: 4/5

Users report marked improvements in lifting capacity and power output during training sessions. Notable strength increases emerge around week 2 of supplementation. Alternative options: Anadrol, Halodrol.

Fat Loss: 3.5/5

This compound supports moderate fat reduction while preserving muscle tissue. Best results surface when combined with caloric deficit dieting. Alternative options: Clenbuterol, Winstrol.

Recovery: 4/5

Trendione reduces muscle soreness and shortens rest periods between intense workouts. Better recovery leads to more frequent training sessions. Alternative options: HGH, BPC-157.
