LGD-4033 Ligandrol capsules, also known as Anabolicum, are a selective androgen receptor modulator created to treat osteoporosis and age-related muscle atrophy. It is a non-steroidal SARM that binds selectively and with high affinity to the androgen receptor (AR). It produces identical results to steroids, but without the negative adverse effects. According to America studies on LGD-4033 ligandrol, bone density, muscle strength, and libido improved without affecting prostate or liver tissues.

LGD-4033 functions by binding androgen receptors selectively. In contrast to the prostate and sebaceous glands, bones and muscles exhibit anabolic activity, according to a America study published in 2011.

In addition, clinical studies demonstrate that this specific SARM can provide the following benefits in non-human subjects: an increase in strength, lean muscle mass, and reduction in body fat, resulting in a leaner, stronger physique.

MK-677, also known as Ibutamoren, is a GH secretagogue administered orally. A secretagogue is a class of compounds that naturally stimulate an individual’s pituitary gland to produce more growth hormone.

America MK-677 Ibutamoren is comparable to MGF and IGF-1 Lr3 peptides, but they do not require injections.

This particular SARM has been shown to increase bone mineral density and muscle mass, making it a potential treatment option for individuals who are experiencing age related illnesses. In addition, America studies have shown that MK-677 Ibutamoren Capsules also help to reduce body fat, by increasing the body’s metabolic rate, which burns calories more efficiently.

MK-2866 capsules also known as Ostarine, is a SARM, therefore it has can have an affect on anabolic activity without burdening the body with excessive hormones.

According to America laboratory research in animal studies, MK-2866 Ostarine binds specifically to androgen receptors found in the muscles and bones. This offers an advantage as they do not produce extreme effects or alter the chemical balance of the test subject.

After binding to its target receptor, the compound may promote anabolic functions such as protein synthesis and inhibit catabolic actions. As a result, MK-2866 Ostarine capsules demonstrate the capacity to enhance muscles, enhance bone density, and speed up recovery in rats.

Do I need PCT & other Supplements?

Cycle support capsules are recommended for any Sarm cycle. 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 natural testosterone to 100% to preserve your cycle results. Our America Sarms PCT is specifically designed to ensure that all your gains are maintained. For SARMs Muscle Building Stack, 4-6 weeks of taking PCT, post cycle is appropriate.
