  • Support increased testosterone levels 24-hours per day, to build muscle and strength
  • Block the negative effects of estrogen
  • Drive libido to new levels
  • Boost natural growth factors
  • Promotes deep sleep for improved recovery                 

Flex Stack Hardcore is a dual attack anabolic activator powered by Methyl Andro Hardocre during the day and Z Test at nighttime designed to overload the system with a constant 24-hour barrage of muscle-yielding testosterone, to facilitate extreme muscle growth and maximize anabolic results. Z-Test’s highly versatile testosterone-boosting formula can be used as a PCT (Post Cycle Therapy) after an intense on-cycle, alone at night to facilitate muscle growth, or in tandem with any daytime testosterone supplement to maximize full anabolic gains.

Methyl Andro Hardcore’s Andro Test Blend features FenuPRO, an anabolic activator that facilitates lean muscle and increases strength. FenuPRO offers 600 mg of Fenugreek Seed Extract, which yields a minimum of 50% Saponins, Furastanolic Saponins, and Protodioscin to help with increases in anabolic strength in the gym! Saponins have been shown to increase the levels of luteinizing hormone, which signals the body to increase Testosterone levels naturally. Methyl Andro’s superior Andro|TEST Blend, which features its dynamic LaxoTest Complex, and its 4-IN-1 TEST SUPPORT Matrix helps amplify testosterone levels, block estrogen and prolactin, increase anabolic strength, and boost natural growth factors.

Z-Test is a dynamic nighttime anabolic catalyst that works through 3 different pathways. First, Z-Test’s exclusive Trib-X Blend helps increase the body’s natural testosterone levels while blocking estrogen. Second, Z-Test increases the body’s natural growth hormone (GH) level with its Nocturnal Growth Blend, to help increase muscle hypertrophy, support lean body definition, and improve muscle recovery. And third, Z-Test promotes a more restful, restorative sleep with the ingredients found in its Mental Relax-5 Blend.*

  • Boost Testosterone: Powerful all natural ingredients found in FenuPRO have been shown to boost free testosterone, the only biologically active form of testosterone. The unique Andro│TEST Blend boosts total testosterone and helps block estrogen.
  • Build Muscle Mass: Methyl Andro Hardcore’s Muscle Growth Blend offers a synergistic approach for building muscle mass. The ingredients in the Muscle Growth Blend help to activate growth factors for quicker recovery and growth development, and elevate natural testosterone levels,a key combination to fuel an intense workout and recovery.
  • Increase Workout Vigor: A decline in testosterone can deplete one’s drive to perform. The 4-In-1 Test Support Matrix found in Methyl Andro Hardcore helps unlock your body’s ability to perform and move past plateaus by supporting your body’s ability to free up bound testosterone, produce more total testosterone, and block the corresponding increase in estrogen that comes with the increase in testosterone production.
  • Improved Muscle Recovery: Sleep is one of the most neglected times to recover and Z-Test increases the body’s natural growth hormone (GH) level with its Nocturnal Growth Blend, to help increase muscle hypertrophy, support lean body definition, and improve muscle recovery. Utilize the nighttime to create a more effective anabolic environment while you sleep!

Increased Strength

Includes 600 mg of FenuPRO Fenugreek Seed Extract and LaxoTest Complex, which is shown to elicit potential increases in strength and vitality and offers dynamic support for amplifying testosterone levels, increasing anabolic strength, and boosting natural growth factors. Enhance your natural strength in each workout for long-lasting results.

Boost Testosterone

Powerful all-natural ingredients and herbs found in Flex Stack Hardcore all work together to further amplify testosterone, block estrogen and prolactin, increase anabolic strength, and boost natural growth factors. This powerful combination can support an increase in natural energy and libido that have declined in the aging process.

Build Muscle

The Pro-Estro Suppress Blend supports the suppression of estrogen and prolactin to isolate the testosterone levels. By suppressing the two, it allows your body to maximize its ability to utilize all the stored testosterone to further maximize each work out and get the most muscle mass and the best muscle definition.

Fast Recovery

Z Test combine natural testosterone boosting ingredients with powerful herbs such as Passion Flower Extract and Chamomile to help relieve and reduce stress, improve focus and concentration, and enhance mood overall. Beneficially, this blend’s ingredients can help make 4 hours of sleep feel like 6 and 6 hours of sleep feel like 8.

Methyl Andro Hardcore: (By Training Level) Take 3 capsules daily. On workout days take 3 capsules 30 minutes before your workout. On non-workout days take 1 capsule 30 minutes before each meal. Methyl Andro Hardcore is best used in cycles of 12 weeks on, 4 weeks off. To be used as part of a physical conditioning program.

Z-Test: Take 3 capsules before bedtime on an empty stomach. Do not consume milk or dairy products 30 minutes before or after taking Z-Test (blocks bioavailability). As a PCT (Post-Cycle Therapy): Use alone for 4 weeks. To be used as part of a physical conditioning program.

Ass kicker!

This is a power combination. Use with purpose, too expensive to waste on ordinary training.

High quality, excellent gains!

This is one of the best boost products I have ever used. Although it is more expensive than many others on the market, I find I get better gains and have much faster recovery with the PMD stack. The sleep boost blend is just enough to help with natural relaxation without making you feel super drowsy or like you’re going to just pass out. Overall, I would highly recommend this product to anyone with a regular, intense workout routine.

Awesome Results

I loved this product. I gained 15 pounds in 8 weeks. I got way stronger and even leaned out in my abs. I noticed more energy throughout the day as well. I body build and this product definitely made the difference.
