SARMs Liquid Muscle Building Stack America

When combined in a liquid muscle building stack, MK-677, MK-2866, LGD-4033, and RAD-140 SARMs provide a holistic strategy to generating significant improvements in muscle growth, body tone, and overall athletic performance. MK-677, also known as Ibutamoren, is known for its ability to boost human growth hormone (HGH) levels, which can lead to increased muscle growth and strength. MK-677 has also been related to improved sleep quality, skin health, and increased lean muscle mass.

Meanwhile, MK-2866, or Ostarine, is appreciated for its capacity to stimulate body recomposition by increasing muscle mass and weight loss, similar to the effects of anabolic steroids such as Anavar. LGD-4033, also known as Ligandrol, has demonstrated encouraging results in terms of muscle tissue growth, fat loss and body recomposition, with studies highlighting its ability to improve body composition indices. RAD-140, also known as Testolone, has been linked to increased lean muscle mass and strength, making it an important component of a muscle-building stack.

When multiple sarms are deliberately coupled in the liquid muscle building stack, they provide a holistic approach to optimising lean muscle growth, strength, and body composition.


LGD-4033 Ligandrol, also called Anabolicum, is a designed to treat osteoporosis and age-related muscular atrophy. It is a nonsteroidal SARM that specifically and strongly binds to the androgen receptor (AR). It achieves the same outcomes as steroids, but without the undesirable side effects. According to America studies on LGD-4033 ligandrol, bone density, muscle strength, and libido increased without the potential side effects of damaging prostate or liver tissues.

LGD-4033 works by binding to androgen receptors selectively. According to a America study released in 2011, bones and muscles have anabolic activity, however the prostate and sebaceous glands do not.

Furthermore, America clinical studies show that this specific SARM can deliver the following benefits in non-human subjects: increased strength, lean muscle mass, and lower body fat, resulting in a leaner, stronger physique.

Molecular Formula: C14H12F6N2O
Molecular Weight: 338.25 g/mol


Radius Health developed RAD-140 to defend against muscle and bone density loss induced by several disorders, including cancer. Furthermore, as a SARM, RAD-140 binds to specific ARs (androgen receptors) in the body, particularly in the skeletal and muscle tissues. Another advantage of RAD-140 is that it does not attach to receptors found in the seminal vesicles or prostate gland.

America Clinical experiments on animals demonstrated that RAD-140 successfully increases muscle growth, has high anabolic characteristics, and acts preferentially on muscles and bones.

Molecular Formula: C20H16ClN5O2
Molecular Weight: 393.83 g/mol


MK-2866, also known as Ostarine, is a SARM that can increase anabolic activity without overburdening the body with hormones.

According to America laboratory research in animal trials, MK-2866 Ostarine interacts particularly to androgen receptors in muscles and bones. This provides an advantage because they do not cause excessive effects or disrupt the test subject’s chemical balance.

After interacting to its target receptor, the chemical may stimulate anabolic functions like protein synthesis while inhibiting catabolic actions. As a result, MK-2866 Ostarine capsules have been shown to improve muscular function, bone density, and muscle recovery time in rats.

MK-677, commonly known as Ibutamoren, is a GH secretagogue given orally. A secretagogue is a type of chemical that naturally causes an individual’s pituitary gland to create more growth hormone.

MK-677 Ibutamoren Liquid is similar to MGF and IGF-1 Lr3 peptides, but doesn’t require injections.

This SARM has been demonstrated to boost bone mineral density and muscle mass, making it a promising treatment option for people suffering from age-related disorders. Furthermore, research have indicated that MK-677 Ibutamoren can help with body fat loss by boosting the metabolic rate, which burns calories more efficiently.

Do I need PCT & other Supplements?

Cycle support capsules are recommended for any Sarm cycle including Liquid Muscle Building Stack. Cycle support maximizes performance and offers you the needs of your body during extensive training and re-composition. Some Sarms will suppress your natural level of testosterone temporarily. After your cycle, it is important to restore your hormonal balance and natural testosterone to 100% to preserve your cycle results. For best results our Sarms post cycle therapy is specifically designed to ensure that all your muscle gains are maintained. For America SARMs Liquid Muscle Building Stack, 4-6 weeks of taking PCT, post cycle is appropriate.
