FLEX Stack ADVANCED is a dual-supporting natural testosterone stack designed to constantly supply the system with non-stop 24-hour testosterone support, which can then help facilitate healthy muscle growth, enhance daily health and wellness, and support numerous men’s health goals.

Powered by N-TEST 600 ADVANCED, a healthy and natural free testosterone booster that contains the clinically-studied Testofen, which has been shown to promote an increase in free testosterone, FLEX Stack ADVANCED maximizes your physiological levels of testosterone to help support lean muscle mass and strength when combined with strength training or exercise.

Phase 2 of FLEX Stack ADVANCED is Z-TEST, a nighttime anabolic catalyst that supports natural testosterone levels, suppresses estrogen, increases natural growth factors, and promotes a more restful, restorative sleep. When these two formulas are used in tandem and have the ability to reinforce each other’s results, they create a stronger more suitable environment to drive advanced results.

  • Lean Muscle Mass, Strength and Endurance: N-TEST 600 ADVANCED includes 10 mg of elemental Boron, 350 mg of Tribulus terrestris, and is reinforced with 150 mg of Smilax officinalis and 100 mg of Black Maca Root Powder. This superior formulation helps to build up healthy testosterone levels and synergistically support increases in strength, size, lean muscle mass and hardness. N-TEST 600 ADVANCED is an ideal choice to help you begin you’re your path toward optimizing your daily health, living an active lifestyle, and reaching your fitness goals.
  • Sexual Health: It is well known that one of the signs of low T is a decreased libido. Among the many ingredients included in both components of FLEX Stack ADVANCED to boost testosterone is the clinically studied Testofen, found in N-TEST 600 ADVANCED. The patent holders of Testofen actually conducted a clinical study on adult male sexual desire and a formulation containing Testofen as a major ingredient showed a statistically significant increase in the sexual function, performance and satisfaction of the active group.
  • Suppress Estrogen: N-TEST 600 ADVANCED is loaded with 100 mg of Diindolymethane (DIM), which is designed to block the estrogen receptors activity and interfering with them to help raise the ratio of testosterone to estrogen. With DIM causing more testosterone to be freed, the results can help support a stronger capacity to build muscle from workouts, a higher sex drive, better moods and improved health. Z-TEST’s formulation helps block estrogen, which helps to avoid the negative and adverse androgenic and estrogen-related side effects commonly associated with natural or artificial sources of testosterone supplementation.
  • Boost Natural Growth Factors: Z-TEST supports the release of more natural growth factor, which the body produces less of with age. Z-TEST uses these growth factors to increase muscle hypertrophy, support lean body definition, and improve recovery.
  • Promotes Restful Sleep: Z-TEST’s formulation also includes ingredients used to promote a more relaxing, restful & restorative sleep to aid recovery.

Boost Free Testosterone

N-TEST 600 ADVANCED contains the clinically studied Testofen, which promotes an increase in free testosterone. Testofen is an extract of fenugreek seed containing steroidal saponins, sapogenins and furostanol saponins. Testofen, unlike other Fenugreek products available today, contains high concentrations of a specific group of saponin glycosides isolated and characterized exclusively by Gencor scientists. These compounds, called fenusides, are the subjects of ongoing research, which Gencor believes will continue to support Fenugreek’s testosterone-promoting benefits.

Muscle Mass

Healthy testosterone levels put your body in an anabolic, or muscle-building, state by helping your body produce and assemble proteins that form the building blocks of lean muscle mass. Tribuls Terrestris tends to increase both free and total testosterone levels. It is believed that it exerts its effects through an increase in Luteninizing hormone (LH) levels, a hormone that signals the body to increase its testosterone production. Smilax Officinalis helps to trigger and signal other hormones to activate in the body. Due to this response, Smilax is believed to help support and stimulate testosterone-like effects that can lead to anabolic strength, energy, and muscle-building results. Combine Flex Stack Advanced with a strength or exercise program for advanced results!

Suppress Estrogen

N-TEST 600 ADVANCED contains 100 mg of DIM and 10 mg of Boron to support a decrease in estrogen. Diindolylmethane (DIM) blocks the estrogen receptors activity, and by interfering with them, it helps raise the ratio of testosterone to estrogen. With DIM causing more testosterone to be freed, this means a result in a higher sex drive, better moods, lean muscle building, and bone-strengthening from workouts. Boron is an essential trace mineral that naturally occurs in certain nuts, fruits, and vegetables, and is known to help decrease and regulate estrogen. Block estrogen at night with Z-TEST. It contains DIM, along with Indole-3-Carbinol and Chrysin. I3C can help reduce estrogen levels while maintaining a healthy hormonal balance. Chrysin is a flavonoid found in passionflower, honey, and bee propolis.

Boost Libido

Black Maca found in N-TEST 600 ADVANCED is loaded with amino acids, minerals, vitamins and antioxidants. With such a strong nutritional profile it’s very deserving of its status as a powerful ‘superfood’. Black Maca has a wide range of supportive health benefits, notably its long-standing tradition of helping to enhance energy, build up stamina, and improve athletic performance. And its benefits have also been linked toward helping with libido and arousing sexual desire.
