Tongkat Ali Root
In 2012 a study published in PubMed of a randomized, double blind, placebo controlled, parallel group study, clinical trial of 109 males, conducted by Hindawi and funded in part by Biotropics Malaysia Berhard, showed significant improvements in libido, sexual performance, satisfaction, physical performance, sperm volume and sperm motility. The plant is used in the traditional medicine of Indonesia, Malaysia and Vietnam. In Indonesia and Malaysia, the root of the plant is boiled in water, and the water is consumed as a health tonic for post-partum recovery, as an aphrodisiac, as well as the relief of fever, intestinal worms, dysentery, diarrhea, indigestion, and jaundice.
Maca has been marketed for its supposed traditional medicinal effects, including a 2016 systematic review found evidence from a small number of studies to improve semen quality in healthy and infertile men.
Panax Ginseng Blend
A 2008 review of studies in the British Journal of Clinical Pharmacology regarding red ginseng and ED found six of the studies reviewed reported improvement in erectile function when compared with a placebo. At the end of the study, the researchers found premature ejaculation decreased and sexual performance improved in those who took red ginseng. 
In a three-month study, Bulgarian researchers gave either a placebo or Tribulus to 180 men, age 18 to 65, with mild to moderate ED, some of whom also complained of low desire. The herb group showed significant improvement: more desire, firmer more reliable erections, and greater sexual satisfaction 
Increased levels of sex steroids have been demonstrated in both men and women after boron supplementation.1,20 In 1987, Nielsen et al1 reported that dietary boron repletion in postmenopausal women (n = 13), who were previously on a low-boron diet, significantly increased their serum estradiol (E2) and testosterone levels, particularly for those women whose dietary intake of magnesium was low. In women on a low-magnesium diet, E2 almost doubled, increasing from an average of 21.1 pg/mL to 41.4 pg/mL. Testosterone more than doubled, rising from an average of 0.31 ng/mL to 0.83 ng/mL. Similar increases were seen in the women on an adequate-magnesium diet: E2 rose from an average of 15.5 pg/mL to 38.0 pg/mL, and testosterone increased from 0.38 ng/mL to 0.65 ng/mL. In 1997, Naghii et al21 published findings of a similar increase in serum levels of E2 in healthy males (n = 18) after 4 weeks of dietary supplementation with boron.
After only 1 week of boron supplementation of 6 mg/d, a further study by Naghii et al20 of healthy males (n = 8) found (1) a significant increase in free testosterone, which rose from an average of 11.83 pg/mL to 15.18 pg/mL; and (2) significant decreases in E2, which dropped from 42.33 pg/mL to 25.81 pg/mL. All of the inflammatory biomarkers that were measured also decreased: (1) interleukin (IL) 6, from 1.55 pg/mL to 0.87 pg/mL; (2) high-sensitivity C-reactive protein (hs-CRP) by approximately 50%, a remarkable decrease, from 1460 ng/mL to 795 ng/mL; and (3) tumor necrosis factor α (TNF-α) by approximately 30%, from 12.32 to 9.97 pg/mL. Levels of dihydrotestosterone, cortisol, and vitamin D increased slightly.

PCT MAX is a tri-blend post-cycle therapy that works in 3 different ways to provide solutions to these 3 problems:
Provides naturally occurring compounds that prevent the body from synthesizing the aromatase enzyme that is responsible for the conversion of androgens(anabolic hormones) to estrogen. Blocking the synthesis of this enzyme doesn’t wipe it out completely though, allowing you to maintain natural estrogen levels (needed for proper function and muscle growth) and you won’t have to worry about diminishing IGF-1 levels which can occur with other Aromatase Inhibitors.
Jumpstarts and skyrockets your natural test production to avoid diminished production rates and even helps to continue to build muscle once the outside Testosterone source is stopped.
Packed with milk thistle and n-acetyl-l-cysteine, this blend helps negate any stress that can be placed on your liver and cleanses any impurities
How Does Androstenolone Work and How is It Different Than A Test Booster?
Androstenolone is considered a prohormone because it is a precursor to more potent androgens such as Testosterone and DHT (dihydrotestosterone). Androgens are hormones that have the ability in the body to bind to what are known as androgen receptors. When these receptors are bound protein synthesis increases greatly and cell growth is turned on. Two of the most potent compounds we know (they have the best affinity for the androgen receptors) are Testosterone and Dihydrotestosterone which are the compounds Androstenolone are converted to in the body. When ingested, tissues in your body metabolizes the androstenolone to generate testosterone and DHT, but androstenolone by itself also has the ability to bind androgen receptors on its own (to a lesser affinity than Testosterone + DHT). So between its conversion to potent androgens and its ability to act as an androgen by itself, Androstenolone is a great mass building compound. Since it's not methylated and not converted by the liver, there is no liver toxicity associated with this prohormone as well!
This differs from a test booster as test boosters work to increase your natural production of testosterone while prohormones actually supply an outside source. TEST Fx contains both of these types of compounds.
Why PCT MAX as Well?
Whenever outside sources of testosterone are supplemented, whether it be the actual hormone or precursors that convert to testosterone after metabolization, it is important to supplement with a PCT: Post-Cycle Therapy. While these are typically associated with the use of anabolic steroids(which we know none of you are abusing), there are many other compounds that work using that same pathway and can generate the same side-effects if a PCT is not used or not used appropriately. For example, our TEST Fx packs 100mg of DHEA per capsule- a strong prohormone that is eventually converted into testosterone once metabolized by the liver. An increase in testosterone can bring along effects from increased estrogen (as there’s more testosterone to be converted to estrogen by the enzyme aromatase), an eventual decrease of natural testosterone production, and the additional work for your liver as that is the site of detoxification for your body.
Tribulus Terrestris- a naturally occurring plant that produces fruit covered with spines and its extract has been used as medicine for a number of various complaints. One of the most studied effects is the ability of the plant to naturally raise testosterone production, in which it has showed increases of an average of 16.3%. More testosterone means way more gains, and it’s even better that it can be done naturally.
DHEA (Dehydroepiandrosterone)– A hormone produced by the adrenal glands, liver, and testes that s a precursor to testosterone and estrogen. When metabolized in the body the DHEA becomes Androstenedione, which then becomes the ever effective muscle packing hormone of testosterone. DHEA has been seen to provide changes in body fat mass and strength. DHEA has also been linked to supporting increased levels of insulin-like growth factor 1, which insulin is one of the most important hormones when trying to put on clean, dense size. DHEA's stimulation of IGF-1 activity is supported by several human trials. These studies have also revealed that DHEA can stimulate GH - growth hormone (somatropin) - release. Therefore, the increase in IGF-1 can be explained by the increase in GH, since GH is converted to IGF-1 in the liver. Growth Hormone and Testosterone…GAINS HERE WE COME!
Deer Antler- Deer antler velvet provides a series of health benefits ranging from improved immune function and mental capacity, to improved cell growth with anti-tumor and anti-viral components. One of the main benefits seen through deer antler velvet however is that it is a natural source of IGF-1, which promotes cell growth. Deer antler velvet has relentlessly proven its strength and endurance increasing abilities, and now it’s your turn to experience it yourself with this 100mg per capsule formula. Do yourself this favor and experience it.
Tongkat Ali Root- a therapeutic herb native to the Malaysian rain forests. Like many other exotic plants, Tongkat Ali is popular in traditional medicine. Its primary use has been to promote healthy libido and support normal hormone levels in males. Tongkat Ali root has been seen to increase free testosterone levels by 104%, and by 88% total testosterone levels. This has repeatedly been shown to increase muscle mass as well. Natural Testosterone? Who wouldn’t want that?
5-Methyl-7-Methoxy-Isoflavone- is a naturally-derived non-hormonal anabolic and anti-catabolic compound known as a flavone. It has been shown to decrease cortisol levels, increase protein synthesis, and improve overall recovery from exercise. This potent , safe, compound works by increasing protein synthesis and nitrogen retention without having the androgenic side effects of steroids. AKA not converting to estrogen. Patented by pharmaceutical experts Chinoin (US Patent # 4,163,746), 5-methyl-7-methoxyisoflavone is designed to promote muscle growth while at the same time increasing fat loss. Even better to add to this compound is the patent shows that it's free from "androgenic or liver-damaging side effects". There have been studies shown that the compound has increased body mass 7%-20%. Gains with no effect on hormone production or organ function, We know you’re all ready to hit your new PR’s.
Rhodiola rosea- a remarkable herb that has a wide and varied history of uses. It is thought to strengthen the nervous system, fight depression, enhance immunity, elevate the capacity for exercise, enhance memory, aid weight reduction, increase sexual function and improve energy levels. It has long been known as a potent adaptogen. Adaptogens are substances that increase the body's overall resistance and help to normalize bodily functions. Since here at CAT5, overall health is the priority and the key to success, we understand the fact of including important healthy herbs. As previous ingredients help overall health as well, this one is a staple. To help increase muscle, rhodiola rosea has been seen to shorten recovery time after prolonged workouts, to increase attention span, memory, strength, and anti-toxic action. Rhodiola rosea extract increases the level of enzymes, RNA, and proteins important to muscle recovery after exhaustive exercise. It also stimulates muscle energy status; glycogen synthesis in muscles and liver; muscle protein synthesis and anabolic activity. However, the herb is also attributed to combating depression through increasing precursors to serotonin, tryptophan, and 5-HTP; relieving stress due to is adaptogen ability to normalize body functions; increasing memory by increasing the bioelectrical activity of the brain which improves memory and brain energy; aid cardiac problems by decreasing the amount of catecholamines and corticosteroids released by the adrenal glands during stress; combat cancerous cells due to its ability to increase anti-tumor activity by increasing the body's resistance to toxins; and improving immune function due to its ability to regulate body functions, decrease stress, and increase natural killer cells in the stomach and spleen. This means gaining muscle, while improving health. Make this commitment to yourself, for yourself!
Alpha Lipoic Acid- is a compound found naturally inside every cell in the body. It's needed by the body to produce the energy for our body's normal functions. Alpha lipoic acid converts glucose (blood sugar) into energy. This promotes healthy energy levels. What’s even better about Alpha Lipoic Acid is that it’s a known antioxidant. This means that it is efficient in neutralizing substances called free radicals that can turn potentially harmful if they attack cells. Alpha lipoic acid is a unique antioxidant as it functions in both water and fat, unlike other common antioxidants, vitamin, and E. Energy+Health= Success in the gym and out for everyone!
