T-UP - Underground Testosterone Booster

There are many products to choose from all claiming to raise testosterone and help build muscle. However, most products have no human studies with healthy males to support their claims. Now Nutrex raises the bar on testosterone boosting by bringing you T-UP Black.

The effects of T-UP's revolutionary Sodium D-Aspartic Acid are supported by science: In one study, the Sodium D-Aspartic Acid used in T-Up led to an average 42% increase in testosterone after only 12 days of use.†

T-UP Black is one of the meanest, cruelest and baddest testosterone boosters this planet has ever seen. Get ready for a significant testosterone surge and muscle gains with T-Up. Where underground and science collide!

  • Study participants experienced a 42% testosterone increase in just 12 days
  • T-UP's Sodium D-Aspartic Acid is scientifically proven to raise testosterone in humans
  • Supports muscle gains, strength increases and recovery
  • Where UNDERGROUND and science collide

† Topo et al., 2009, Reprod. Biol. Endocrinol. 200, 7:120. Study lasted 12 days and showed an average increase of 42% in total testosterone levels. The effects of D-Aspartic Acid on free testosterone were not investigated. Although only free testosterone provides the muscle enhancement and other benefits associated with testosterone, many experts agree that an increase in total testosterone is accompanied by a similar increase in free testosterone.

  • Q:

    I just got the shredded stack and i read a little bit more into T-Up and i dont want to use it, is there another supplement that you can recommend i could take instead, that would also show great results

      A:

      If you seeking to receive similar benefits without increasing testosterone production, I would recommend Anabol-5. Anabol-5 is a non-steriodal product that does not directly increase testosterone. It assists in building muscle size and strength by helping to increase protein synthesis and also supports a postive nitrogen balance. Both are anabolic conditions vital for muscle growth. Here is a link for further information http://www.nutrex.com/nutrex/anabol5.asp#prPaContaineranabol__5
      Another option for you would be to take Vitrix. Vitrix is another natural tesosterone booster that gives you similar end results as T-UP but with different ingredients. Vitrix has been a very popular product for the last 7 years.

    • Staff Reviewer

      A:

      Yes, T-UP is an extremely effective formulas that is designed to increase your body's own production of testosterone. With higher testosterone levels, your body is able to increase protein synthesis, increasing the amount of protein your muscle can absorb throughout the day leading to gains in lean muscle and strength gains. Also, can help to enhance stamina while you train/run and speed up muscle recovery. To receive the full benefits, it is best taking with a high protein diet as well as supplementing with a high quality protein powder like Muscle Infusion to meet your protein intake needs. Yes, it can be taken with Lipo-6 Black UC. T-UP is best taken between meals on an empty stomach. For the first 10 days we recommend a loading phase where you take 5 Black Liqui-Caps twice per day between meals. From day 11 on you can switch to the regular testosterone boosting protocol and simply take 5 Black Liqui-Caps once per day between meals.

    Asked on 5/31/2013 by adam from New York

    • Staff Reviewer

      A:

      T-UP is considered to be a safe supplement and has never been known to cause adverse side effects. As long as you are a healthy individual and take the product as directed, you should have no issues. However, males who are predisposed to male pattern baldness or acne should be aware that T-UP has the ability to further contribute to these issues. T-UP is designed to boost your body’s natural production of testosterone. With higher testosterone levels, your body’s is able to increase protein synthesis, increasing the amount of protein your muscles can absorb throughout the day. When stacked with a high protein diet, this can lead to gains in lean muscle and quicker recovery.

  • Q:

    I have seen that some test boosters can have the side effect of testicular atrophy, and before i start going into a regiment i wanted to know if this is a possibility with T up black
    Asked on 5/28/2013 by R

    • Staff Reviewer

      A:

      T-UP works by helping your body increase it's natural testosterone production and has never been shown to cause any negative effects on your body ability to produce testosterone. Testicular atrophy is usually associated with adding a foreign hormone to your system such as testosterone or a derivative of testosterone. When this occurs your body stops its natural production and this is what causes the testicular atrophy. As T-UP works with your natural production it will not have this type of effect.

  • Q:

    Do I have to do the loading phase to achieve good results with T-Up Black, or can I still see significant gains without doing the loading phase?
    Asked on 5/25/2013 by DLandes

    1 answer

    • Staff Reviewer

      A:

      That's a great question. The loading phase will simply allow the formula to become saturated in your system quicker. Without the loading phase you will still most likely receive the same overall benefits but it may take a little longer to get there.

      A:

      Our T-UP utilizes a capsules composed of vegetable cellulose. If this has happened as a result of using T-UP this would most likely be the cause. Vegetable cellulose is a very safe and effective alternative to using gelatin composed of animal products. I can reassure you that while this reaction may look alarming, it is in no way harmful to you.

      A:

      Yes, both T-UP and Anabol-5 work with different mechanisms in your body but produce similar results. Because of this, they can be stacked together to help create a heightened anabolic state.

      Test boosters are a dime a dozen today but let us break this one down.
      1st the loading phase, easy to do, not complicated really feels like it helps make you a monster in the gym. It stacks well with other supplements and works great.
      My review of the 1st phase - fealt like I could work out longer and heavier than before.
      Second phase Maintenance - easy to follow, easy to understand, easy to do.
      Kept the energy high, no or little side effects of moodieness or anything.
      Off cycle - easy to maintain strength gains and it felt like there was little boomerrang effect of the test dropping low and then coming back to normal in my body.

              I have only been using T-up for nearly two weeks now and so far so good. Like any testosterone booster, T-Up Black is great for both cutting and bulking. However, from my research (note to experienced lifters and athletes), this product is designed to only raise t-levels to a normal state not necessarily more. So if you're hoping for a mega professional body builder type t-increases, you may be a bit disappointed although this is still a great supplement overall if trying to cut and retain gains.

                T-Up was very helpful in helping me retain muscle gains after cutting. Within the first 2-3 weeks I was able to notice the visible changes in my physique as I became leaner and more defined, yet still muscular. This was my first time using T-Up, and although it may be a bit pricey for perhaps most people, I will still be purchasing a second bottle.
