I noticed you completely ducked the issue of the eurycomanone content not being stated on the label of your product. Instead you choose to rush to the defence of LJ100 which isn't used in your product!
I'm aware LJ100 is the physta form used in studies and you know what? That doesn't mean Jack because the results of studies that have used LJ100 are virtually non existent in relation to healthy humans. Ive posted on this before. See quote from Examine. If you have any decent studies contradicting this please post links to these. We know the Tambi conference presentation everyone seems to rely on has never been published or peer reviewed
There is a lot of sketchy research on Eurycoma and testosterone, a lot of studies claiming an increase in testosterone but citing conference presentations. Currently, there are only two studies conducted on noncastrated rats measuring testosterone and they both use bad doses (one too low, the other too high).
Currently, no good evidence suggests that normal men increase testosterone from Eurycoma. Those with hypogonadism might, but the 46% value is inflated given they had very low testosterone at baseline anyways
0.8-1.5% bioactive Eurycomanone content? Well I know a few other products which provide double this and are more cost effective. We know that you have to use massive doses of LJ100 to possibly get any significant test increases. Anything less you're better off with a deep restful night's sleep which will do far more to boost your test levels. When I pick up a bottle labelled test booster I'm interested in straight up test increases. If I want related health benefits there are tonnes of more cost effective products and I'll select the specific ingredients I think I need.
I agree KSM-66 can be relatively cost-effective but you have to for right priced products. There are too many overpriced options marked up just for bearing the KSM-66 branding . Sensoril is another good alternative but obviously you have a vested interest in pushing one form because its in your bottle. I have used several products and have found none sensoril and ksm-66 products that work just as well for me.
I'm glad we can at least agree taking single ingredients is a great, more flexible and, in my view, more cost effective alternative to 'all you need n a bottle' multi ingredient test boosters currently profliferating
My product? We weren't even discussing that brand in this thread, so I felt that I'd keep it respectful and only discuss Diesel Test and Testify; I didn't see a need to introduce a third option when it wasn't asked for; I don't want to pimp for the sake of pimping. If you're talking about the product I think you're talking about, it is actually also standardized for 2% Eurycomanone (read the write-up on Priceplow). Why are you attacking that lack of disclosure, but completely ignoring that another product that was actually asked about by OP doesn't list standardization on the label, or doesn't disclose it at all (not that that's inherently wrong, it's just a different approach).
EDIT: I thought you were asking about the eurycomanone content of LJ100, I must have missed that you mentioned "my product," as it wasn't even mentioned at all, so it didn't even cross my mind. I'm not sure why that was brought up, but I guess now you can see that's it's a pretty nice dose.
Here's a study on tongkat ali that may be interesting. On the subjects:
healthy married men between 30 years and 55 years of age or those with stable chronic medical illnesses, for example, controlled diabetes mellitus and/or hypertension on monotherapy or low dose combination therapy were included (accepted comedication in obese and overweight subjects, for example, antidiabetic drug metformin and hypertension, for example, antihypertensive drug amlodipine, atenolol, perindopril). Subjects were excluded with major uncontrolled psychiatric disorders, history of alcohol or drug abuse, history of major hematological, renal or hepatic disorder, stroke or myocardial infarction within the last six months, peptic ulcer or bleeding disorder, elevated blood pressure beyond the range of 90/50 to 170/100 mmHg, clinically relevant baseline laboratory abnormality, and/or use of herbal products or drugs that could contain testosterone or any androgenic activity in the last month before start of trial. These products and alcohol were also not permitted during trial.
On the results:
For the first time a placebo-controlled clinical trial with 109 randomized male subjects demonstrated for a freeze-dried water extract of the roots of Eurycoma longifolia (Physta), significant improvements in libido, sexual performance, satisfaction, and physicial functioning. E. longifolia has a strong impact on seminal fluid parameters, for example, semen volume and sperm motility. The daily dose of 300 mg of E. longifolia extract for three months is well-tolerated and safe compared to placebo.
It may be worth noting that it was funded by Biotropics Malaysia, but that doesn't mean that it's a useless study:

And here's another study on moderately stressed subects:
These results indicate that daily supplementation with tongkat ali root extract improves stress hormone profile and certain mood state parameters, suggesting that this “ancient” remedy may be an effective approach to shielding the body from the detrimental effects of “modern” chronic stress, which may include general day-to-day stress, as well as the stress of dieting, sleep deprivation, and exercise training.
This study did also receive funding from Biotropics Malaysia, in the interest of full disclosure:

Also, if I've said it once, I've said it a hundred times, natural test boosters are not going to increase your testosterone to supraphysiological levels, and slight fluctuations within the normal range are not going to provide significant increases in muscle mass or strength. With that said, it is unwise and short-sighted to ignore other MoAs that some of these ingredients work via. For example, while forksolin HAS been shown to increase testosterone, I'd say it's more useful for it's ability to increase cAMP levels and improve body composition. As for ashwagandha, it has uses as an adaptogen, which are valuable, in addition to it being able to increase testosterone (yes, it has been shown to increase testosterone). When I think of what a "test-booster" should provide, I think of the benefits associated with increased testosterone (increases in strength, endurance, body composition, mood, libido, etc), if a product can provide me with these, then I am satisfied with it, and, if I already have normal testosterone levels, see no need to even get lab work done, as I know it's not going to bump me into supraphysiological levels, and isn't all that relevant to anything besides saying it is. I know I certainly wouldn't prefer feeling or seeing no benefits but having a slight but meaningless increase in lab work.
Also, if you go through and read my post history, I do mention many times that Sensoril is also a quality extract, and I have used products with both KSM-66 and Sensoril. I don't see why you're so keen on coming after me though, but oh well, I appreciate a healthy debate, and I respect and appreciate that you are keeping it civil.
Some of my mentions/praise of Sensoril:
I love ashwagandha. It has so many benefits; cortisol control, stress/anxiety reduction, cognition, strength, body composition, cholesterol, etc.
Are you using KSM-66, Sensoril, or something else, and what dose? You probably already know, but you really want to make sure the withanolide content is standardized according to HPLC, not gravimetry or titration, as the latter two will give much higher readings than HPLC (KSM, Sensoril, and a few other quality extracts use HPLC).
On Sensoril and KSM-66
Both are quality extracts.
That's just a few, so don't accuse me of something that is not true. I've also referenced Sensoril studies in various threads, including one that used Sensoril at 50mg/day withanolides, a higher dose than the 30mg/day used in the majority of KSM-66 studies that noted improved "ognitive and psychomotor performance." There is also another study on KSM-66 showing cognitive benefits, which is pretty cool.
If you're looking for ingredients that have been shown to increase testosterone, and want to pick things up alone, perhaps try some of these:
Ashwagandha (600mg/day of 5% withanolide HPLC or equivalent withanolide content HPLC)
Shilajit (500mg/day of Primavie, I forget exactly what it's standardized for)
Forskolin (500mg/day of 10% forskolin extract or equivalent forksolin content)
They all have research showing increases in testosterone; I referenced them earlier in this thread.
Cheers, and good luck with your supplement goals my friend.
Let us not derail this thread further with arguing/debating. If you want to discuss anything farther, and I always enjoy a good debate, we could either PM or start a new thread. Sound good?
