yeah i heard of it. bulbine natalensis is awesome used properly. its actually a 247% increase in test, but anthony roberts has this funny math that includes the 100% you already produce. its still awesome. i give credence to proper dose and right extraction/storage as evidenced by my use of various brands; basically there is a thin margin where a user gets the 247%increase, but if you go beyond that you actually have less test than you normally would, which is bad. ergotest uses something called prolensis, which has tested people for the right dose and has taken the steps necessay to preserve the extract, resulting in a standardized product you can count on. i tried one that had a 100x extract and i experienced a reduction in my normal libido and good mood; from that i concluded the dose was too high, and interestingly, i read forums where other users reported the same thing, albeit 7 days further down the road. ive also tried phytoserms 347% which uses the same prolensis that ergotest uses. it had a very noticvable increase in libido. i didnt get muscle gains or add 5-7lbs of bodyweight like the label claimed, but the supernormal libido was cool; the most ive heard of any herbal test booster is libido and maybe some leaning out, but i dont expect huge gains given the guys on roads can go 22x over baseline testosterone. anyway, i felt like pytoserms botched it by adding stinging nettle to free test up; i know the principle is good, but im skeptical because, for example, the anti aromatase stuff has a good principle, yet users experience drops in libido. i also feel like tropinal, another company that carries the legit prolensis, messed up by adding caffeine for the cheap high; as if im gonna think its a test surge or something. anyway, i dont want the cortisol from that crap on my muscles anymore than i want the vasoconstriction at my junk, so im excited about this ergotest, as it has instead opted to refrain from the frills in offering a very potent herb at a reasonable price. i hold bulbine natelensis in higher regard than any test booster simply to the fact that increases natural production of test while lowering estrogen 30%, as opposed to gaining test thats turning into estrogen. this stuff also has a long cvcle. i view this product as an awesome libido enhancer and something that retores people to high school test levels; very sound natural stuff. i just ordered ergotest today and i will be forming som conclusions comparing this to phytoserms which uses stingin nettle
