Concealed Labs Mass 900 60 caps anabolic stack

Mass 800 is a powerful anabolic stack, a product containing ingredients with anabolic effect, which ensures rapid gains in muscle mass. The product has been specially designed for athletes who expect an extraordinary increase in strength and endurance. When using Mass 800, it is recommended to consume more than normal amount of protein, because during the cycle on prohormones it is much more absorbable and the body uses it for high muscle gains. It is also important to ensure the right amount of carbohydrates and fats, because the process of building muscles requires huge amounts of energy.

Concealed Labs Mass 900 60 caps is:

  • Strong anabolic effect,
  • Combination of 5 SARMs,
  • Fast increase in muscle mass,
  • Significant improvement in quality,
  • Strong load and muscle pump.

Due to the increase in metabolism and thermogenic transformation, supplementation with vitamins, minerals and proper hydration of the body are also important.

Concealed Labs Mass 900 60 caps stack anabolic composition:

1 serving, 1 capsule:


Turkesterone (Ajuga Turkestanica Extract 10%) - 300 mg - is a natural ecdysteroid that is gaining popularity as an ingredient of dietary supplements. Its anabolic effect, similar to testosterone, but without binding to androgenic receptors, makes it an attractive alternative for people looking for safe support in building muscle mass. By stimulating muscle protein synthesis, Turkesterone can contribute to faster regeneration after training, protection against catabolism and increased endurance, which makes it a valuable addition to the diet of athletes.

Ecdysterone (20 Hydroxyecdysone) - 100 mg - also known as 20-Hydroxyecdysone, is another plant steroid that has muscle growth-promoting properties. Research suggests that it may help increase muscle mass, strength and improve muscle regeneration without directly affecting testosterone levels. Ecdysterone, like Turkesterone, is considered a safe and effective ingredient of dietary supplements, especially appreciated by strength athletes and bodybuilders.

Laxosterone (5a-Hydroxy Laxogenin) - 50 mg - is a substance of plant origin that can support the body in the natural growth of muscle mass. Its anabolic effect, without affecting the hormonal balance, makes it an interesting option for people looking for an alternative to synthetic steroids. Laxosterone can help improve muscle protein synthesis, increase strength and better body composition, which makes it increasingly chosen by athletes and physically active people.


Stinging Nettle Extract (3,4-Divanillyltetrahydrofuran 95%) - 100 mg - nettle extract is a valued ingredient of supplements supporting testosterone levels. Research indicates that it may affect sex hormone binding protein (SHBG), which in turn may increase the amount of free testosterone in the body. Additionally, nettle is known for its anti-inflammatory properties and can support prostate health, which is important for men who care about optimal testosterone levels.

Macuna Pruriens (58% L-dopa) - 100 mg - contains L-dopa, a precursor of dopamine, which may increase testosterone production by stimulating the secretion of luteinizing hormone (LH). LH is a key hormone in the process of testosterone synthesis. Mucuna pruriens is also used in Ayurvedic medicine and may contribute to improved mood and overall well-being, which can also have a positive effect on hormone levels.

Horny Goat Weed (Epimedium Extract 70%) - 50 mg - is an herb traditionally used in Chinese medicine that may support sexual function and libido. It contains icariin, which may act as a natural PDE5 inhibitor, just like some erectile dysfunction drugs. Although the evidence for a direct effect on testosterone levels is limited, some research suggests that it may indirectly influence testosterone levels by improving sexual function and libido.

Tongkat Ali Extract (Eurycoma longifolia) - 50 mg - in traditional Asian medicine as a means of improving physical and sexual abilities. Scientific research suggests that Tongkat Ali may increase testosterone levels, which is crucial for men who want to improve their physical performance and libido. Thanks to the content of compounds that can stimulate the production of luteinizing hormone, Tongkat Ali contributes to the natural synthesis of testosterone in the body.

Arimistane (Androst-3,5-Dien-7,17-Dione) - 25 mg - is an aromatase inhibitor that may contribute to lowering the level of estrogen in the body, which in turn helps maintain higher testosterone levels. Arimistane is valued by athletes and bodybuilders for its potential ability to help build muscle mass and reduce body fat. Its action may also contribute to improving strength and endurance, which is especially important during periods of intense training. Additionally, Arimistane can support regenerative processes after exercise, which is important for people actively practicing sports.


Ostarine (MK-2866) - 12.4 mg - is a selective androgen receptor modulator (SARM) that was developed to treat conditions such as osteoporosis and sarcopenia, as well as other muscle wasting conditions. As a SARM, Ostarine intentionally binds to androgen receptors in muscle and bone tissues, which may help to increase muscle mass and strength without affecting other tissues such as the prostate or liver, which is a common problem with the use of anabolic steroids. Studies have shown that Ostarine can significantly increase lean body mass, which makes it an attractive ingredient for people seeking to improve their figure and increase performance. 

Testolone (RAD-140) - 10 mg - is another SARM that mimics the effects of testosterone, but with greater selectivity than traditional anabolic steroids. Testolone was designed to provide anabolic benefits without the negative side effects associated with steroid hormones. Thanks to its ability to selectively stimulate muscle and bone growth, Testolone can help increase muscle mass, strength and improve overall body composition.

Ligandrol (LGD-4033) - 5 mg - works by selectively binding to androgen receptors in muscles and bones, which may lead to increased muscle mass and strength. This is especially beneficial for people who want to build muscle and improve their physical performance, while minimizing the risk of side effects associated with traditional anabolic steroids. Ligandrol is valued for its strong anabolic effect, which can contribute to the rapid increase in muscle mass and strength, which is crucial for people who actively train.

Anamorelin (ONO-7643) - 1 mg - is a ghrelin receptor agonist that has anabolic effects, which may contribute to increasing body weight and muscle strength. As a ghrelin mimetic, anamorelin may affect the levels of growth hormone (GH) and insulin-like growth factor (IGF-1), which are important in the regulation of metabolism and may support anabolic processes, including protein synthesis in muscles.

Ibutamoren (MK-677) - 1 mg - is a ghrelin mimetic and may increase the secretion of growth hormone and IGF-1. This action may translate into improvement of anabolic parameters, such as an increase in muscle mass and strength, as well as optimization of energy management. In the context of testosterone boosters, ibutamoren may support regenerative and anabolic processes in the body, although its direct effect on testosterone levels is not clearly established. It is worth noting that ibutamoren is not legally allowed for sale and its use may be considered doping.


Grape Seed Extract 95% - 15 mg - is a valued ingredient of testosterone booster supplements, mainly due to its antioxidant properties. The proanthocyanidins contained in it may contribute to improving circulation and the condition of the circulatory system, which is important for men who care about their testosterone levels. In addition, this extract can support lipid profile parameters, which translates into better overall health and may indirectly affect testosterone production.

Vitamin E TPGS - 15 mg - which is a water-soluble form of vitamin E, is another ingredient that may have a positive effect on testosterone levels. Vitamin E is a known antioxidant that protects cells against the harmful effects of free radicals. Its presence in testosterone boosters may contribute to the protection of Leydig cells, responsible for testosterone production, which may contribute to increasing its level in the body.

Naringenin - 5 mg - a natural ingredient found in grapefruits, a compound that may affect metabolism and hormone functioning. As a powerful antioxidant, naringenin may support cardiovascular health, which is important for maintaining adequate testosterone levels. Additionally, its effect may contribute to the reduction of fat tissue, which is beneficial for men trying to increase muscle mass and strength.

Piperine 95% - 5 mg - has the ability to increase the bioavailability of other ingredients by inhibiting hepatic metabolism processes, which may contribute to better absorption of substances such as curcumin or selenium.

Vitamin B12 (as Cyanocobalamin) - 500 mcg - is a key ingredient in testosterone booster supplements. It plays an important role in the production of red blood cells and contributes to the proper functioning of the nervous system, which may affect testosterone levels.

Vitamin D3 (As Cholecalciferol) - 10,000 IU - may help increase muscle mass by increasing testosterone and energy levels. Research indicates that higher doses of vitamin D3 may be needed to achieve the testosterone-boosting effect.
