Bulbine Natalensis

Bulbine Natalensis is a potent African herb that has become a popular addition to supplement stacks catered to those who want to boost libido and testosterone levels.  This herb has been used in traditional medicine as a natural aphrodisiac, and has had numerous studies conducted on it.  However, in supplement form it is better known as prolensis, while in its herb form Africans call it ingcelwane, rooiwortel, and ibhucu.

Bulbine natalensis has been studied on male rats with very promising results, but critics claim that the dosages given to the rats are not realistic to humans.  However, in this particular case the dosages would translate to very conservative amounts in humans, where it would actually be affordable and realistic.  In simple terms, the results of this study were as follows:

  1. The rats showed a doubling of their testicular weight, meaning that on a steroid cycle you can utilize bulbine to prevent testicular shrinkage.  For instance, you can easily test this out on yourself by diving into your steroid cycle, waiting until your testicles start to shrink up, and then using bulbine.  You should notice after a few days that your testicles become larger.
  2. There was a boost in LH (luteinizing hormone) and FSH (follicle stimulating hormone).  Therefore, during your post cycle therapy, bulbine will help you recover faster and better.  These types of results are synonymous with what happens when SERMS (such as clomid and nolvadex) are used, but without the nasty side effects that come with them, and without the drop in IGF-1 levels either.
  3. In addition to the raise in LH and FSH, bulbine will also directly stimulate them, causing a sharp rise in testosterone levels.  In fact, studies showed that testosterone rose by a whopping 347% when using bulbine!  For further proof of these effects, cholesterol count within the testicles rose, and this confirms that indeed testosterone levels went higher.
  4. To top it off, bulbine was shown to drop estrogen levels by 30%.  This comes in handy both during, and after cycle, when estrogen can become an issue and can potentially offset the testosterone boost you get.

User results

Users who run bulbine report an increase in libido, testicular growth, and better results athletically.  Furthermore, those using bulbine during cycle say it helps them keep estrogen under control and gives them a softer landing after cycle.  Meanwhile, when used for post cycle therapy, users say they do not feel as hard of a crash as they come off hormones, and that they are able to recover faster.  Hence, it makes them hold onto more strength and muscle, while keeping fat down.

Side effects

The center for applied health sciences conducted a human trial on bulbine to see if there were any adverse effects, and found no issues at all.  However, just like with any supplement, you should never overdose bulbine, and must use it as directed.  When used improperly or abused, these types of testosterone boosters can affect the kidneys, and even the liver.

How to dose

Bulbine can be dosed anywhere from 200 to 600 milligrams (mg) per day, and works even better when stacked with fadogia agrestis.  You can use it on cycle, during PCT, and during bridge.  It is non suppressive, so feel free to use bulbine anytime.

Where to find

Bulbine can be found in certain supplements, but it is usually under-dosed.  Hence, due to the poor quality and low amounts of the active substance it is just a waste of money to use these supplements.  The good news is that there is one particular supplement stack called Phytoserms-347, which is sold at N2BM.com, and it contains the best bulbine directly from Africa, as well as other ingredients to help athletes, or just the normal joe looking to boost his libido.
