From another forum, whilst researching bulbine (and why i feel like Im a bloated woman) I came across this....
You’re all being ripped off.
About 1 year ago Bulbine Natalensis hit the Dietary Supplement industry and raised quite the commotion. Claiming to raise testosterone levels by 347%, the buzz was profound to say the least. Since its release, numerous companies have included this ingredient in their products with great results and reviews from end users. The most glowing/positive reviews are coming from a specific form of Bulbine Natalensis known as ProLensis™ as this was the exact extract used in the clinical studies proving the power of Bulbine Natalensis. The extract is unique as it is a 10:1 concentrate, and it contains specific ratios of saponins and alkaloids that have been proven time and time again to raise testosterone.
Unfortunately, not every company is willing to pony up the cash for legitimate raw materials, so the vast majority of products that claim to include Bulbine Natalensis are vastly inferior and will not produce results even remotely similar to those found in the clinical studies. Now while ProLensis™ is obviously the most effective form of Bulbine Natalensis, it would make sense that these cheaper/inferior extracts would at least give us some decent gains…right?
A certain company is currently marketing a product which claims to be “100% Bulbine Natalensis” at a whopping 500mg/capsule. They have prided themselves on the fact that it is not a proprietary blend, and that giving people this amount per pill enables users to finely tune their dosing to correspond to their weight(Don’t forget, Bulbine Natalensis will raise testosterone up to a certain point, and then if you take too much, it will reduce your testosterone levels). They’re logic behind this dosing is
So it seems like they’ve read the studies, and understand how to make sure that people take the right dose. The only problem is their math is COMPLETELY wrong. So wrong in fact it is 100% guaranteed that following the dosing of this product will in fact reduce your testosterone levels.
The study this company is referencing used Wistar rats as their subjects and found that a dose of 25mg-50mg/kg was the most effective dose of ProLensis™. So according to this study, if you’re a rat and want a 347% increase in testosterone, you need to be taking 25-50mg/kg of bodyweight.
What’s that you say? You’re not a rat? You’re a human? Well that changes everything.
Common knowledge in the pharmaceutical industry as well as most of the dietary supplement industry shows us that to convert a dosage from any animal (in this instance a rat) to a human, a simple formula must be used to compensate for Body Surface Area(BSA). The fact is that the more body surface area an organism has, the lower the dose/kg will end up being. So to be clear, an animal with a low BSA(such as a rat) will need a higher dose per kg of weight than an animal with a high BSA(such as a human or a 1,000lbs Moose for that matter). So you can figure out the proper dosing for yourself, here is the formula set up in its basic form, as well as with the proper numbers thrown in for both 25mg/kg and 50mg/kg.
Bulbine Natalensis Conversion formula:
Dose = 25mg/kg * (6/37)
Dose = 25mg/kg *(.162)
Dose = 4.05mg/kg
Dose = 50mg/kg * (6/37)
Dose = 50mg/kg *(.162)
Dose = 8.10mg/kg
So now we have a true dosing pattern for humans(again, if you’re a rat, please stick with the doses used in the study!) so we can see what each of us should be using to get gains comparable to the study. The company in question uses an 80kg(176lbs) man for their dosing, so we will as well.
80kg x 4.05mg(25mg/kg in rats) = 324mg
80kg x 8.10(50mg/kg in rats) = 648mg
Now just to be clear, what this math is telling us is that an 80kg man, should be taking inbetween 324-648mg/day, or they run the risk of lowering their testosterone instead of raising it. So if this is the case, why in the heck would this company be suggesting an 80kg man take 8 tablets a day, or 4,000mg of Bulbine Natalensis? They are giving users 15-20x more than the study calls for. If this was any other ingredient I’d say “go stock up now!” however this is one of the only ingredients where more is NOT better.
In fact, the only way for this product to work is it you weigh exactly 61.5kg(135lbs), and consume anywhere from ½ a capsule(good luck dumping out ½ a capsule each day) to 1 capsule per day. If you weigh 80kg like they estimate you will, you’ll need to take 2 capsules/day, which puts you well over the dosing threshold which means you will LOWER your testosterone levels!
So now where does that leave us? Should no one take Bulbine Natalensis? Absolutely not! You just need to choose a brand like RLS that actually knows how to use studies, science, and proper dosing protocols to ensure you get the results you deserve! Look for only brands that utilize ProLensis™ Bulbine Natalensis as they are guaranteed to be dosed properly and effectively due to research by the companies who offer it, as well as the manufacturers!
I'm gonna give 1 Tab a go, and report my results. It certainly doesn't feel like my test is higher on high dose (12 tabsx500mg) bulbine compared with TauroTest, , or .. I feel like ive been on the booze all night and im retaining loads of water
