PeptiStrong® – 2,400 mg

Developed by AI, PeptiStrong® is plant-based peptide complex derived from fava beans (Vicia faba), clinically studied for anabolic, anti-catabolic, and muscle preservation benefits.

• Stimulates mTORC1 activation, promoting muscle protein synthesis without the need for high leucine or animal protein intake.
• Increases muscle fiber size and muscle strength, particularly in aging and stressed populations.
• Reduces expression of muscle atrophy-related genes like Murf-1 and Atrogin-1.
• Enhances muscle recovery and preservation during periods of inactivity, disuse, or calorie restriction.
• Helps retain lean mass post-exercise without increasing fat mass.

Synergy: Works synergistically with Quercetin and Recoverben® to reduce catabolism, inflammation, and oxidative stress, enhancing muscle retention during overreaching or caloric deficits.

Quercetin (Sophora japonica) – 1,000 mg

A flavonoid sourced from the flower buds of Sophora japonica, standardized to quercetin dihydrate—the most bioavailable form.

• Reduces post-exercise inflammation and oxidative stress (lowers IL-6, TNF-α, and CK).
• Increases mitochondrial biogenesis and VO₂ max through PGC-1α upregulation.
• Supports recovery from eccentric or high-volume training by preserving muscle cell integrity.
• Protects against muscle loss during stress or inflammation by modulating NF-κB and FoxO signaling.
• Enhances endurance and work capacity in repeated bout exercise trials.

Synergy: Amplifies anti-catabolic and endurance-boosting effects of PeptiStrong® and Maral root, while enhancing recovery synergy with Recoverben®.

Recoverben® Lemon Verbena Extract – 400 mg

A clinically studied, proprietary extract of lemon verbena standardized to high levels of verbascoside, an antioxidant polyphenol with anti-inflammatory and pain-relieving effects.

• Reduces muscle soreness and stiffness after eccentric exercise.
• Accelerates muscle strength recovery post-training.
• Inhibits pro-inflammatory enzymes (COX-2, 5-LOX) and cytokines (IL-1β, TNF-α).
• Improves sleep quality and perceived recovery in active individuals.
• Protects mitochondria against oxidative stress, preserving cellular energy output.

Synergy: Enhances anti-inflammatory effects of Quercetin, supports the muscle regeneration and strength restoration functions of PeptiStrong®, and pairs with Maral root to promote recovery and resilience.

Maral Root Extract (Rhaponticum carthamoides) – 350 mg

An adaptogenic root extract rich in ecdysteroids (esp. 20-hydroxyecdysone), used traditionally in Eastern Europe to improve physical performance, lean mass, and recovery.

• Increases muscle protein synthesis via PI3K/Akt and mTOR pathways.
• Improves muscle strength, anabolic signaling, and endurance in resistance-trained subjects.
• Enhances recovery and reduces fatigue through adaptogenic and antioxidant mechanisms.
• May increase work output and total training volume via CNS stimulation and mitochondrial protection.
• Supports lean mass gains without androgenic side effects.

Synergy: Complements PeptiStrong® by boosting anabolic signaling, works with Quercetin and Recoverben® to buffer stress and inflammation, and promotes total performance resilience.

Synergy Overview 

Anabolic Signaling + Muscle Protein Synthesis: PeptiStrong®, Maral Root, and Quercetin converge on mTORC1, PI3K/Akt, and ecdysteroid-linked anabolic pathways to increase lean mass, fiber size, and strength—without hormones or excessive protein intake.

Anti-Inflammatory & Muscle Recovery: Recoverben®, Quercetin, and PeptiStrong® work together to reduce soreness, downregulate IL-6/TNF-α, and protect muscle tissue after training—accelerating functional recovery between sessions.

Mitochondrial Support & Endurance: Quercetin, Recoverben®, and Maral Root increase mitochondrial density, reduce oxidative damage, and improve VO₂ kinetics, promoting endurance and faster energy turnover.

Anti-Catabolic & Muscle Preservation: PeptiStrong®, Quercetin, and Maral Root prevent breakdown of muscle proteins during caloric restriction, overtraining, or aging by suppressing atrophy genes and oxidative stress markers.

Adaptation, Resilience, and Performance Output: Maral Root, Recoverben®, and PeptiStrong® support central fatigue resistance, muscular resilience, and mood/adaptogenic tone, helping maintain higher training volumes over time.
