Liquid Bulking Stack Germany

The use of RAD-140, YK-11, and MK-677 in a liquid bulking stack provides a holistic approach to muscle growth, strength increase, and overall performance improvement. RAD-140, also known as Testolone, is known for its ability to develop muscle, increase strength, and improve endurance, making it an essential component of the stack. YK-11, which is known for its anabolic qualities and testosterone-boosting effects, supplements RAD-140 by encouraging further anabolic activity and potentially contributing to increased muscle mass.

Furthermore, the inclusion of MK-677 in this liquid sarms stack, which is known for its capacity to boost muscle growth and increase sleep quality, adds to the bulking stack’s synergistic effects, perhaps providing a more holistic approach to muscle development and overall physical performance. When used in unison, this SARMs Stack can constitute a potent combination in a bulking stack to help individuals achieve great muscular gains and strength.


YK-11 SARM is a synthetic compound that was first discovered by Japanese researchers in 2011. Unlike other SARMs, YK-11 also acts as a myostatin inhibitor, which means it can potentially boost muscle growth beyond what traditional SARMs can do. However, as a research chemical, its safety and efficacy have yet to be fully established.

RAD-140 was originally developed by Radius Health to protect against muscle and bone density loss caused by diseases including cancer. Furthermore, with RAD-140 being a SARM, RAD-140 binds to specific ARs (androgen receptors) in the body, specifically the skeletal and muscle tissues. Another advantage of RAD-140 is that it does not bind to the receptors in your seminal vesicles or and prostate gland.

Germany Clinical trials in animals confirmed that RAD-140 effectively increases muscle mass, possesses strong anabolic properties, and acts selectively in the muscles and bones.

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

MK-677 Ibutamoren Liquid 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, Germany studies have shown that MK-677 Ibutamoren can also help to reduce body fat, by increasing the body’s metabolic rate, which burns calories more efficiently.

Do I need PCT & other Supplements?

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