ITEM/SIZE
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:
Should I avoid alcohol during a cycle of T-UP?Asked on 5/6/2013 by BigDude6 from Illinois1 answer
A:
Occasionally consuming alcohol has never been shown to cause negative effect when taking T-UP. However, alcohol consumption has been shown to have a negative effect on your testosterone levels and your body's ability to burn fat. If you are serious about bodybuilding I would recommend keeping alcohol consumption to a minimum.Answered on 5/6/2013 by Nutrex from Oviedo, FL
Q:
How much Sodium D-Aspartic Acid contains one serving of T-UP Black?Asked on 5/5/2013 by Dmitry1 answer
A:
The exact amount of D-Aspartic Acid cannot be disclosed due to the fact that it's part of a proprietary blend that made the formula unique. It is very comparable per serving to the amount utilized in the study. Here is a link to the study http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2774316/?KeepThis=true&TB_iframe=true&height=800&width=1000Answered on 5/6/2013 by Nutrex from Oviedo, FL

plus how would you advise my usage as im in afganistan with the army
and iv been trining over 2 yearsAsked on 4/27/2013 by ..j from afganistan1 answer
A:
T-UP is recommended to be taken for a full cycle length of 12 weeks followed by a 4 week off-period. Increasing testosterone levels naturally as with T-UP hasn't been shown to cause aromatization to the point where a PCT/estrogen blocker would be necessary. When you incorporate hormonal products where you are introducing a foreign hormone to your system which in turn un-naturally elevates your testosterone levels past the point of which would be considered an effective/reasonable dose, this is where you need to be concerned about aromatization. If you stay clear of products such as pro-hormones and continue to use products such as T-UP or even Vitrix then you will not need an anti-estrogen.Answered on 4/29/2013 by Nutrex from Oviedo, FL

A:
Yes, regardless off your training, to receive the full benefits off T-UP we suggest a 10 day 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.Answered on 4/22/2013 by Nutrex from Oviedo, FL

Q:
Will I "crash" after cycling off T-UP? Can T-UP in any way negatively impact my body's ability to produce testosterone?Asked on 3/28/2013 by BigDude6 from Illinois1 answer
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. Once you stop using the product your levels should return to their normal state.Answered on 3/29/2013 by Nutrex from Oviedo, FL
Q:
Is this safe for a 16 year old that lifts 5x a week?Asked on 3/27/2013 by rt from ohio1 answer
A:
No, this product is only recommended for individuals 18 years of age and older. At your age I would suggest a high quality protein powder like Muscle Infusion. Supplementing with this 2-4 times daily along with a proper diet and training routine can help aid in muscle recovery and gains in lean muscle mass.

Reviews about Nutrex Research T-UP Black:
I could tell a difference in my energy levels while taking T-UP, but I can't say much for strength levels. I also would like the product to deliver a full 30 day supply, as it only gives 20 days taken as prescribed.

Reviews about Nutrex Research T-UP Black:
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.

Reviews about Nutrex Research T-UP Black:
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.

Reviews about Nutrex Research T-UP Black:
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.
