SARMs Shredding Stack

When combining S4, MK-2866, SR-9009, and GW501516 SARMs in a shredding stack, the potential benefits for body composition improvement are multifaceted, allowing the user to gain all the benefits from multiple research chemicals. For instance, MK-2866, also known as Ostarine, is recognized for its ability to improve strength, increase endurance, and increase lean muscle mass while promoting healing. Additionally, SR-9009, commonly referred to as Stenabolic, is associated with improved weight loss through enhanced energy output. Furthermore, clinical studies have found that GW501516, or Cardarine, contributes to increased fat burning and heightened energy levels. The combination of these SARMs in the Shredding Stack from Direct SARMS offers the potential for significant muscle mass gains, improved endurance, accelerated weight loss, and overall body recomposition


S-4 was created to treat osteoporosis (a bone condition that causes bones to become weak and brittle), muscle wasting, and benign prostatic hypertrophy (an enlarged prostate). Andarine (S4) works by binding to androgen receptors with bone and muscle selectivity. It works by modifying gene expression, which leads to a significant increase in protein synthesis and body anabolism.

S-4 Andarine Capsules anabolic effects have been compared to the anabolic substance Stanazole, with identical results. However, S4 has a greater influence on muscle growth and protection. This product is ideal for burning fat and protecting muscles when performing low-calorie diets, intensive aerobic activities or resistance training.

MK-2866 capsules, commonly known as Ostarine, are a SARM, which means they can impact anabolic activity without burdening the body with extra hormones.

According to laboratory research in animal trials, Ostarine MK-2866  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 lean muscle mass, muscular function, bone density, and muscle recovery time in rats.

GW-501516, commonly known as Cardarine, is frequently mistaken for a sarm, however it is actually a peroxisome proliferator-activated receptor (PPAR) agonist. GW-501516 and SARMs have certain fundamental properties, yet they differ significantly. For example, GW-501516 has modest effects on testosterone levels and androgen receptors. GW-501516 Cardarine Capsules have gained popularity because of their capacity to boost the body’s fatty acid metabolism, thus resulting in a reduction of body fat.

Cardarine stimulates gene expression and allows the body to release energy even when at rest. As a result, sporting individuals and bodybuilders receive energy increases for strenuous activities that they would not otherwise get from normal activity thus improving endurance.

SR-9009 Stenabolic Capsules is an agonist of REV-ERB that regulates metabolism and circadian behaviour. It has potential use in treating metabolic diseases and sleep disorders.

The Stenabolic SR-9009 protein is found in various locations throughout the body, including the liver and skeletomuscular system. Studies have shown that it regulates circadian rhythms, acts on fat-storing cells, and influences the liver’s lipid and glucose metabolism. Although SR-9009 is not a SARM (selective androgen receptor modulator), it binds to Rev-ErBA and produces many same effects as SARMs.

In treated mice, SR-9009 Stenabolic was highly effective at increasing metabolic activity and skeletal muscle growth. However, it does not affect the level of endogenous testosterone. It works by activating as well as binding protein structure together and increasing mitochondria number within the muscle tissue. Increasing mitochondria number within your muscle mass cells, research has suggested boost muscular strength and endurance.

Do I need PCT & other Supplements?

Cycle support capsules are recommended for any Sarm cycle including the SARMs Shredding 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 Sarms PCT is specifically designed to ensure that all your gains are maintained. For SARMs Shredding Stack, 4-6 weeks of taking PCT, post cycle is appropriate.
