🔍 Ingredients Breakdown (per capsule)




  • Rhaponticum carthamoides (Standardised to 80% Ecdysterone) – Anabolic Power from Nature


    Rhaponticum carthamoides, commonly known as Maral Root, is a plant native to Siberia. It has long been revered in Russian and Eastern European traditional medicine for its adaptogenic and rejuvenating properties. However, its true fame in the world of sports supplementation comes from its high content of Ecdysteroids, especially Ecdysterone—a naturally occurring compound with anabolic-like effects but without hormonal side effects.
    Ecdysterone is classified as a plant-based phytoecdysteroid. Unlike synthetic anabolic agents, it exerts its effects through a non-hormonal pathway. Studies have shown that ecdysterone enhances muscle protein synthesis by activating the PI3K/Akt pathway, leading to accelerated muscle repair, hypertrophy, and strength gains — all while being safe for the liver and endocrine system.
    One of the most significant advantages of Ecdysterone is that it doesn’t interfere with the body’s hormonal balance. This makes it suitable for both men and women and allows it to be used safely without the need for post-cycle therapy (PCT). It has also shown positive effects on nitrogen retention, endurance, and even glucose metabolism, supporting lean gains and fat loss at the same time.
    Ecdysterone’s profile makes it an excellent choice for athletes seeking:


    • Faster recovery


    • Increased lean mass


    • Improved resistance to physical stress


    • Enhanced muscle density


    • Improved power output and strength


    This product’s extract is standardized to 80% Ecdysteroids, ensuring high potency and consistency in every dose. This is one of the most potent and most concentrated forms of Ecdysterone on the market, giving users the most anabolic effect available from a natural source.
    Whether you’re looking to push through a training plateau, maintain lean mass during a cut, or want a performance edge without touching hormones, Rhaponticum carthamoides is a premium, safe, and effective ingredient to add to your stack.


✅ Dosage – Timing – Follow-Up




  • Dosage: Take 1–2 capsules daily.


  • Timing: Preferably in the morning or around training sessions.


  • Follow-Up: It can be safely used in cycles of 8–12 weeks. Due to its non-hormonal profile, no PCT is required.
