Tribulus Terrestris Extract


Androgen Amplifier


Tribulus is an herb commonly believed to boost testosterone levels.  It contains Protodioscin, a steroidal saponin that demonstrates aphrodisiac and pro-erectile effects.  Protodioscin administration up-regulates androgen receptors, increasing sensitivity to androgens.  Protodioscin also triggers release of nitric oxide (NO) in the corpus cavernosum, and increases levels of the sex hormones in animal studies.  However, the subject remains controversial because human data is often inconsistent.  One thing's for sure though, most guys who try it think something in it works!


Trigonella (Fenugreek Seed Extract)


Glycogenic and Steroidogenic Herb


Fenugreek contains sterols that are similar to those found in Tribulus, and stacking the two produces excellent synergism.  However, unlike Tribulus, several studies actually do show an increase testosterone and free-testosterone with Fenugreek supplementation.  Notable benefits include:   Increased libido, decreased body fat, lower blood sugar, reduced cholesterol levels, and reduced 5-alpha reductase activity.  This is one of those herbs that really works, and can even be used as a PCT ingredient when suppression is mild.


Lepidium meyenii (Maca Root)


Adaptogenic Aphrodisiac


This South American root is used for its adaptogenic effect.  It's been speculated to possess MAOI activity based on its exotic spectrum of beta-carbolines.  If this is true, it may help to explain its popularity as a sexual performance enhancer.  Although there is insufficient evidence to prove that it helps with erectile dysfunction, a great number of users assert that it's aphrodisiac properties are not just figments of their imagination.


Pine Pollen Extract


Herbal Androgen


Pine Pollen is known to contain Androsterone, and Androsterone is an androgenic hormone with a great number of biological benefits.  Pine Pollen is used by athletes to improve stamina, boost endurance, and build more muscle.  It is also said to possess positive mental effects, like improved alertness, focus and memory.  It's got a long history of use as a performance enhancer in China, were everyone ranging from school children to the elderly are encouraged to take it daily!


Epimedium (Horny Goat Weed Extract)


Phosphodiesterase Inhibitor


Epimedium is another traditional Chinese herb, and it's extracts are shown to increase nitric oxide (NO) levels.  It also causes up-regulation of genes associated with NO production, which may serve to make NO donors more effective at lower doses. 


PDE5 inhibition is a popular strategy for treating erectile dysfunction, and Epimedium contains several compounds demonstrating PDE5 inhibitory properties.  The best studied of these compounds is Icariin.  Icariin is proven to have cognitive benefits.  It can be mildly stimulating and may promote insomnia in sensitive individuals.  Icariin is also a testosterone mimic, meaning it can substitute for real Testosterone, but it isn't shown to inhibit natural Testosterone production.


25R-Spirostan-3b,5a-diol-6-one  (5a-Hydroxy-Laxogenin)


Steroidal Sapogenin


5a-Hydroxy-Laxogenin (or just Laxogenin for short) is an all-natural phytosterol which has been shown to possess notable anabolic activity.  While several popular sterols are known to have athletic benefits, and many others are suspected to have anabolic effects, Laxogenin is documented as the real deal.


It is generally regarded as not as strong as anabolic steroids, but still impressively potent for a plant sterol.  Respectable gains are usually achieved with its use and strength is reported to sometimes increase rapidly.


It is not known to cause liver issues like some synthetic compounds can, and tested athletes are generally not prohibited from using plant sterols such as Laxogenin.


Clinical testing has revealed that Laxogenin can increase protein synthesis by several times over average values, which is great for repair, recovery and lean tissue growth in general.


Laxogenin tends to balance cortisol, which helps to prevent muscle wasting during periods of caloric restriction and also discourages fat gain and immune dysfunction.  Even with these notable corticometric effects, users state that their joints are none the worse for it.  In fact, the majority experience alleviation of pre-existing joint problems!  This is significant, because practically every other anti-cortisol product on the market tends to dry joints out, especially at higher doses.


Other desirable qualities of Laxogenin are reported to be positive blood glucose regulation, and increased metabolism and thyroid function.


Most of the scientific information on Laxogenin seems legit and very encouraging, but it is mainly obtained from manufacturers and from an old 1970's publication in the  journal Phytochemistry.  Besides a handful of additional references, little else is known about this exciting new compound.  However, user feedback cannot be ignored and is overwhelmingly positive, so we decided to make the best Laxogenin product available - Laxobol.


Indole-3-Carbinol (I3C)


Estrogen Metabolic Modulation


Indole-3-carbinol is a compound found in cruciferous vegetables such as broccoli, cauliflower, and greens.  It has been studied extensively to elucidate the mechanism by which it inhibits growth of various reproductive carcinomas.  In these studies, I3C has been found to alter estrogenic metabolism.  This occurs in such a way as to shift metabolic pathways, resulting in lower conversion to strong estrogens and greater proportional conversion to weaker estrogens.  This means weaker estrogen expression and less suppression of HPTA from estrogenic contributors. 


Androsta-3,5-diene-7,17-dione  (Arimistane)


Potent Aromatase Inhibitor and Corticometric


Arimistane is an endogenous metabolite of DHEA, and could be viewed as the 3-Deoxygenated version of another metabolite called 7-Keto-DHEA.  It acts as a relatively potent aromatase inhibitor (AI) and moderate cortisol antagonist.   That means it will reduce estrogen and cortisol, which eliminates a source of negative feedback that normally acts to limit testosterone production.  But with these pathways shutdown, and a steady lowering of SHBG in response, this induces an endocrine situation that blows the door wide open to greatly enhanced testosterone biosynthesis AND increased free testosterone levels as well.  


With testosterone levels up, muscle mass improves and recovery is faster.  With free-testosterone up, libido is usually exaggerated.  This effect on sex drive is relatively persistent, but often most dramatic in the initial half of treatment. 


Also, with estrogen levels and cortisol expression down, fat stores are burned and the metabolism is not well suited for making new stores.  This can have its drawback though, and some users report joint pains with cortisol and estrogen down.  Men require a certain, minimal level of estrogen to maintain libido, which is another good reason not to get greedy with the dosing.  Both joint pain and low sexual desire are side effects almost never encountered, except with excessive dosing.  Reducing dose to the recommended level almost always solves such problems promptly.  


Although Arimistane is a natural and legal compound, ingredients this effective are usually subject to eventual sports ban.  It is therefore always recommended that competitive athletes check the rules of their specific organization before use.


Zinc Oxide


Male Mineral


Zinc is involved in numerous enzymatic processes, and is an essential element commonly deficient in athletes.  That's not good, because Zinc is especially important in athletic performance!  Zinc deficiency can lead to anorexia, weight loss, chronic fatigue, exercise intolerance, and osteoporosis.  But once supplementation begins, deficient athletes notice restoration of strength and muscle mass, better reproductive function, less sick time, and improved blood glucose levels.   Research also shows that Zinc lowers the risk of prostate cancer, which should inspire not just athletes but all men to consider it's supplemental importance.


Folic Acid (Vitamin B9)


Essential Growth Factor


Folic acid is an essential B Vitamin (B9) that plays many vital roles, but there are a few key benefits we would like to highlight specifically.  First is B9's ability to reduce homocysteine, a metabolite of the amino acid L-Cysteine.  Homocysteine appears to be a key risk factor in heart disease, so reducing its level is an important consideration. 


B9 also helps increase triglyceride metabolism, which improves lipid profiles.   B9 plays a role in the metabolism of neurotransmitters, and has been used as an adjunct in antidepressant therapy.


But perhaps most importantly, low B9 leads to classic macrocytic anemia.  It is therefore crucial in the growth and regeneration of red blood cells, and this is particularly important for athletes in order to keep RBC counts high and oxygen carrying capacity at max.
