Product Introduction

SR9009 (Stenabolic) is a REV-ERBα agonist that increases metabolic rate, enhances endurance, and promotes fat burning by regulating biological clock genes. It is not a SARM or steroid, but a metabolic regulator, and has attracted attention in the fields of fitness and competitive sports for its unique "hormone-free" energy-enhancing mechanism.

Core fitness effects and mechanisms

✅ Significantly improve endurance and athletic performance

Activate mitochondrial biosynthesis and increase the number and efficiency of cellular energy factories (mitochondria).

Increase maximum oxygen uptake (VO₂max), delay fatigue, and is suitable for endurance training (long-distance running, cycling) and high-intensity interval training (HIIT).

Research data: In animal experiments, SR9009 increased exercise endurance by more than 50% (similar to Cardarine but with a different mechanism).

✅ Accelerate fat metabolism (fat loss magic)

Enhance basal metabolic rate (BMR), and continuously promote fat oxidation (especially stubborn fat) for 24 hours.

Inhibit fat storage genes (PPARγ), and reduce new fat formation.

No risk of muscle breakdown (unlike fat loss drugs such as Clenbuterol).

✅ Improve biological clock & recovery ability

Regulate REV-ERBα gene, optimize sleep-wake cycle, and improve deep sleep quality.

Reduce inflammatory response and accelerate recovery after training.

✅ No hormonal side effects (high safety)

Does not interfere with the androgen/estrogen system, no hair loss, acne, hormone suppression and other problems.

👉 Summary:

SR9009 is a "biological clock replacement" for Cardarine, which is safer but requires frequent dosing (short half-life).

Clenbuterol has stronger fat-reducing effects, but has severe side effects. SR9009 is more suitable for long-term use.

Recommendations for use (dosage, cycle, combination)

🔹 Dosage and frequency of administration

10-30mg/day, divided into 2-3 doses (because the half-life is only 2-4 hours).

Best time: morning, before training, afternoon (avoid affecting sleep at night).

🔹 Usage cycle

Fat loss period: 6-12 weeks (can be used for a long time, without hormone dependence).

Endurance sprint: 4-8 weeks before the race (such as marathon preparation).

🔹 Golden combination plan

Fat loss: SR9009 + Cardarine (double metabolic activation, double the effect).

Endurance assistance during muscle gain: SR9009 + MK-677 (reduce fatigue and improve recovery).

Side effects and precautions

**⚠️ Potential problems**

Short half-life: multiple doses are required per day (not convenient enough). Animal experiments show a slight increase in liver enzymes (it is recommended to use NAC to protect the liver).

🚫 Contraindications

Pregnant/lactating women (biological clock regulation may affect the fetus).

Severe liver disease patients (although rare, but need to be cautious).
