Olympus Labs Trenavar (TR3N Trendione) Review: The Raw Truth About This Powerful Prohormone

Quick Summary

Olympus Labs Trenavar (TR3N Trendione) is an extremely potent prohormone that converts to trenbolone in the body, delivering dramatic muscle gains and strength increases within 2-3 weeks, but the severe side effects including significant testosterone suppression, elevated liver enzymes, aggressive mood changes, night sweats, decreased cardiovascular capacity, and potential long-term health damage make it too dangerous for most users to justify.

The compound requires extensive support supplementation (liver protection, blood pressure management, cholesterol support) and mandatory post-cycle therapy with SERMs like Clomid or Nolvadex, yet still causes noticeable physical strain that can be felt throughout the body, elevated liver values on bloodwork despite protection, and hormonal crashes that affect libido, energy, and overall wellbeing for weeks after the cycle ends.

Currently, I strongly advise against using Trenavar – the short-term physique improvements (5-10 lbs lean mass, dramatic strength gains, enhanced vascularity) are not worth risking your liver health, cardiovascular system, hormonal balance, and long-term wellness, especially when safer alternatives exist that provide substantial results without the extreme health risks.

Trenavar is incredibly effective at what it does, but the side effects and health risks are significant enough to prevent a higher score. Here’s my breakdown:

• Effectiveness for muscle gains/strength: 5/5
• Effectiveness for fat loss/hardening: 4.5/5
• Safety profile: 2/5
• Health risk level: 2/5
• Value for money: 4/5

I give Olympus Labs Trenavar an overall score of 3.5/5. It’s undeniably powerful, but the physical and health demands it places on your body make it appropriate only for the most experienced prohormones users.

What natural safer, alternatives can mimic Trenavar/Trenabol

Natural/Legal Supplements (No Side Effects, No PCT Required)

• Creatine Monohydrate (5g daily) – Proven strength and muscle gains, completely safe long-term
• Beta-Alanine (3-6g daily) – Enhanced endurance and training capacity
• Citrulline Malate (6-8g daily) – Improved blood flow, pumps, and performance
• Turkesterone (500-1000mg daily) – Natural ecdysteroid for muscle protein synthesis without hormonal effects
• HMB (3g daily) – Muscle preservation during cutting, anti-catabolic effects
• Leucine/EAAs – Muscle protein synthesis support without any hormonal manipulation

Mild Prohormones (Moderate Effects, Manageable Side Effects, PCT Recommended)

• DHEA (25-100mg daily) – Mild testosterone precursor, minimal side effects, legal
• 4-DHEA/4-Androsterone (200-300mg daily) – Converts to testosterone, less liver toxic than methylated compounds
• 1-Androsterone/1-DHEA (200-330mg daily) – Converts to 1-testosterone for lean gains with lower side effect profile
• Epicatechin (250-500mg daily) – Myostatin inhibitor for natural muscle growth, very safe
• Laxogenin (100-200mg daily) – Plant-based anabolic, no hormonal suppression

Moderate Prohormones (Stronger Effects, Requires Proper PCT & Cycle Support)

• Epiandrosterone/3-Epi-Andro (100-200mg daily) – Converts to DHT for hardness and strength with moderate suppression
• 19-Nor-DHEA (100-200mg daily) – Converts to nandrolone for joint support and muscle gains
• 7-Keto DHEA (100-200mg daily) – Metabolite that doesn’t convert to testosterone/estrogen, fat loss support

SARMs (Selective Androgen Receptor Modulators – Research Chemicals, Moderate Side Effects)

• Ostarine/MK-2866 (10-25mg daily) – Mild muscle building, good for beginners to PEDs
• Ligandrol/LGD-4033 (5-10mg daily) – Stronger muscle building than Ostarine, more suppression
• RAD-140 (10-20mg daily) – Significant strength and mass gains, requires PCT

Important Notes on Alternatives:

• Start with natural options first – Maximize creatine, protein, training, and recovery before considering anything hormonal
• If using prohormones/SARMs – Always use liver support (NAC, TUDCA), get bloodwork before/after, and run proper PCT
• Cycle responsibly – 6-8 weeks on, 4-8 weeks off minimum for any hormonal compound
• Never stack multiple prohormones as a beginner – assess tolerance with single compounds first
• These alternatives provide 60-80% of Trenavar’s results with 20-30% of the health risks – a much better risk/reward ratio

The reality is that no supplement will replicate Trenavar’s extreme potency without extreme risks. If you’re not willing to accept liver damage, hormonal shutdown, and cardiovascular strain, focus on optimizing training, nutrition, recovery, and using safer compounds that still deliver meaningful results without potentially permanent health consequences.

After spending years testing various supplements—from basic creatine to complex prohormones—I’ve developed a solid understanding of what works and what’s marketing hype. Today, I’m taking a deep dive into Olympus Labs Trenavar (TR3N Trendione), one of the most potent prohormones still available on the market.

If you’re considering this supplement, you need the unfiltered truth about what you’re getting into. This isn’t your basic testosterone booster—it’s pharmaceutical-grade territory that demands respect.

What Exactly Is Trenavar?

Olympus Labs Trenavar contains 30mg of Estra-4,9,11-Triene-3,17-Dione (Trendione) per capsule. This compound converts to trenbolone in your body after ingestion. For those unfamiliar with trenbolone, it’s one of the most powerful anabolic compounds with an anabolic rating of 500 compared to testosterone’s 100.

The capsules contain minimal additional ingredients: just microcrystalline cellulose, magnesium stearate, silicon dioxide, and gelatin capsules. There’s no proprietary blend nonsense here—you know exactly what you’re taking.

My Experience With Trenavar

I’ve tried many prohormones over the years, and Trenavar stands out as one of the most potent. Within the first week, I noticed significant strength increases—adding 15-20 pounds to my major lifts. By week two, my physique started changing noticeably.

The muscle hardness and vascularity were unlike anything I’d experienced with other supplements. My recovery between sets improved dramatically, and I could train with higher intensity without hitting a wall.

What impressed me most was the lack of water retention. The gains were dry and quality—when I looked in the mirror, I saw defined muscle, not the puffy look that comes with many bulking compounds.

The Results You Can Expect

Based on my experience and feedback from other users, here’s what you might achieve with a proper 4-week cycle:

• 5-10 pounds of lean muscle (with proper diet and training)
• Significant strength increases across all lifts
• Enhanced vascularity and muscle hardness
• Accelerated fat loss while maintaining or building muscle
• Improved recovery between workouts

The changes come quickly, but remember—this isn’t magic. You still need to eat right and train hard. Trenavar amplifies your efforts rather than replacing them.

The Dark Side: Side Effects I Experienced

I wouldn’t be giving you an honest review without discussing the downsides, and there are several with Trenavar:

The suppression hit me hard around week three. My natural testosterone production took a serious dive, leading to lethargy and decreased libido. This isn’t surprising given how powerful this compound is, but it was still rough.

I experienced noticeable aggression—both in and out of the gym. While the gym aggression helped with training intensity, the short fuse in daily life wasn’t pleasant.

My liver values were elevated during post-cycle bloodwork, despite using support supplements. The strain on my body was evident—I felt it in ways that milder supplements never caused.

Night sweats became a regular occurrence, waking up with damp sheets despite keeping the room cool. I also noticed a decrease in cardiovascular endurance, getting winded more easily during any cardio work.

Dosage and Cycling Recommendations

Based on my experience, I’d recommend starting with 1 capsule daily for the first week to assess tolerance. If sides are manageable, you can increase to 2 capsules daily (one morning, one evening with food).

Never exceed 3 capsules daily, regardless of your experience level. The recommended cycle length is 4 weeks maximum—going beyond this significantly increases health risks with diminishing returns.

Post-cycle therapy is non-negotiable with Trenavar. I used a SERM (Selective Estrogen Receptor Modulator) like Clomid for 4 weeks following my cycle to restore natural testosterone production.

Who Should Consider Trenavar

This supplement is exclusively for experienced users who:

• Have completed several cycles of milder compounds
• Are at least 21 years old (preferably 25+)
• Have no existing health conditions (especially liver, heart, or prostate issues)
• Are willing to invest in proper support supplements and post-cycle therapy
• Can commit to pre- and post-cycle bloodwork

If you’re new to the world of prohormones, this is not where you start. The risk-to-reward ratio is unfavorable for beginners who haven’t established proper workout and nutrition routines.

Required Support Supplements

If you decide to use Trenavar, these support supplements aren’t optional:

• Liver support: NAC (N-Acetyl Cysteine), TUDCA, or milk thistle at full dosages
• Cycle support: Products containing ingredients for blood pressure and cholesterol management
• Post-cycle therapy: A proper SERM like Clomid or Nolvadex

The cost of these support supplements should be factored into your decision—proper protection can easily double your overall expense.

My Overall Rating: 3.5/5

Trenavar is incredibly effective at what it does, but the side effects and health risks are significant enough to prevent a higher score. Here’s my breakdown:

• Effectiveness for muscle gains/strength: 5/5
• Effectiveness for fat loss/hardening: 4.5/5
• Safety profile: 2/5
• Health risk level: 2/5
• Value for money: 4/5

I give Olympus Labs Trenavar an overall score of 3.5/5. It’s undeniably powerful, but the physical and health demands it places on your body make it appropriate only for the most experienced and determined users.

Final Thoughts: Is Trenavar Worth It?

If you’re looking for dramatic physique changes in a short timeframe and are willing to accept the risks, Trenavar delivers results that few legal supplements can match. The dry, quality gains and strength improvements are impressive.

However, if you’re concerned about your long-term health or aren’t prepared for the commitment of proper support supplementation and post-cycle therapy, there are safer alternatives that produce more modest but still significant results.

Trenavar is a serious compound for serious users. If you choose to use it, do so with full awareness of what you’re getting into. The gains will come quickly, but they come at a cost that not everyone should be willing to pay.
