In the world of bodybuilding supplements, specifically with natural testosterone booster supplements such as T-UP Black, Animal Stak, or T-Bomb, you have many choices, and it becomes a tough pick. Throw in the Infinite Labs Cyclo Bolan NT, and the choices doesn't get any easier. But I think if one decides to give Cyclo Bolan a shot, you'll quickly find that this is one heck of a good test booster supplement. It's formula is relatively simple, without any fillers, and it works exceptionally well to boost strength increases along with testosterone gains.
Infinite Labs Cyclo Bolan claims to:
Promote dramatic strength gains
Greater muscle growth and muscle hardness
Reduced estrogen and DHT conversion
I've already mentioned that Cyclo Bolan is a very effective testosterone booster supplement that works very well to increase strength gains. But let's dig a little deeper and take a quick look at its ingredients. Below is a quick list of the key ingredients in Cyclo Bolan:
Horny Goat Weed
Yohimbe Bark Extract
Bioperine (peperine extract)
Tribulus Terrestris is a natural testosterone booster ingredient that most people are probably familiar with. It works on the Lutenizing Hormone (LH), which in turn stimulates the production of testosterone. Horny Goat Weed (HGW) has long been used as an aphrodisiac that increases sexual desire, libido, and sperm production. Nettle root, or stinging nettle (Urtica Dioica) has some significant applications for use in natural testosterone booster supplements. Various studies have found it to inhibit sex-hormone binding globulin (SHBG) by binding to it. By inhibiting SHBG, it effectively increases your total amount of free testosterone.
Yohimbe has energizing and aphrodisiac effects, and it also increases blood flow to the genitals for both men and women. Yohimbe helps fight impotence and erectile dysfunction, increases libido, and helps improve sexual performance.
There are some other test boosters that include the use of DHEA, but it's not something that you see all that often. DHEA is a weak androgen that's a precursor of testosterone; however, it could also undergo further conversion to estrogen. Overall, there isn't a whole lot of scientific evidence that supports the use of DHEA to enhance athletic performance. Furthermore, there's some contradicting evidence of DHEA where a study done by Morales et al. found that DHEA supplementation helped to increase muscle strength while reducing body fat in men, but not in women. Other studies, however, found DHEA to have no noticeable effects on strength or body composition. Another study done on the effects of DHEA on stressful military training found that supplementing DHEA enhanced anabolic balance during the sustained military training stress. 
My feeling here is that DHEA does work to some extent, and it does help with some of the increase in strength gains as I experienced while taking Cyclo Bolan NT. I felt a bit stronger after taking Cyclo Bolan, and was able to really blast through my workouts at a high intensity - it gives you a slight edge. My libido was up quite a bit, as expected. So no surprises there. As far as side effects go, I didn't experience any unpleasant side effects of Cyclo Bolan NT. If you're looking for a good testosterone booster, give this a try.
