Higher testosterone levels may increase growth hormone levels, supporting faster muscle building, strength gains, and easier fat burning.

Magnesium and Reishi mushroom extract inOsta 2866 may help support glucose metabolism by regulating glucose uptake to the muscle cells. Such a mechanism helps fuel the muscles, maximizing performance and energy levels. 

OSTA 2866 contains terpenes and polyphenols, active compounds that may reduce muscle inflammation and wasting. Such effects promote faster muscle recovery post-exercise.

The makers claim Osta 2866 may support metabolic function, enabling you to burn fat more efficiently. It could help you improve your body composition and overall physical appearance.

Osta 2866 Ingredients

  • Zinc

    Zinc supports enzymatic reactions. It may support protein synthesis and hormone production, specifically testosterone production. Such effects may enhance muscular strength and promote hypertrophy.

  • Magnesium

    Magnesium helps support energy production and glucose metabolism. It helps regulate insulin sensitivity, providing optimal glucose supply to fuel the muscle cells. It could increase skeletal muscle function, reduce muscle inflammation, and enhance strength and endurance. Magnesium can regulate muscle contractions and support the transmission of nerve signals, allowing for smooth movement and coordination.

  • Southern Ginseng

    Southern ginseng contains plant compounds called gypenosides that may improve blood flow to the muscles, reducing feelings of tiredness and fatigue during workouts. It possesses antioxidant properties that could reduce inflammation and exercise-induced muscle damage. Southern ginseng could increase muscle fiber recruitment and help negate the effects of delayed onset muscle soreness (DOMS), providing faster recovery from physical exertion.

  • Salacia

    Salacia possesses anti-obesity effects, which may regulate insulin levels and improve insulin sensitivity. These effects improve lipid metabolism and support fat burning. It could inhibit the production of inflammatory molecules, relieving muscle pain and exercise-induced muscle soreness. 

  • Fennel 4:1 Extract

    Fennel 4:1 extract may promote optimal hormonal balance by curbing the growth of excess estrogen. It may help raise free testosterone levels and support lean muscle growth and repair. It could support healthy muscle structure by increasing muscle fiber density and size, improving muscle performance and lifting capacity. Fennel 4:1 extract may curb unhealthy food cravings by promoting satiety and suppressing leptin levels (a hormone that triggers hunger).

  • Reishi Mushroom Extract

    Reishi mushroom has a rich anti-inflammatory profile that could reduce muscle soreness, stiffness, fatigue, and inflammation. It may increase training frequency and provide optimal muscle strength and size outcomes.

  • Cinnamon Extract

    Cinnamon extract contains compounds that may enhance the body’s ability to utilize glucose, improve insulin sensitivity, and maintain healthy metabolic function. It could enhance the body’s response to insulin, essential for transporting glucose into cells for energy production. Cinnamon extract could also support healthy testosterone production, positively affecting muscle growth, recovery, and repair.
