S4 (Andarine)

Beschrijving

Product Description: S4 by Core Labs

S4 by Core Labs is a selective androgen receptor modulator (SARM) used to support body reconstruction, promote muscle growth, and aid in fat loss with little or no side effects. Its key functional compound is S-3- (4-acetylamino-phenoxy) -2-hydroxy-2-methyl-N- (4-nitro-3-trifluoromethyl-phenyl) -propionamide, also known as Acetamidoxolutamide or Andarine.

S4 can stimulate androgen receptors in muscle and bone tissues, thereby accelerating muscle development and bone mineralization. Notably, GTX 007, unmethylated for liver safety, does not cause an increase in blood pressure or negative changes in the lipid profile.

How S4 Works

S4 uses its selective action of specific androgen receptors to develop desired structures. In particular, S4 binds to target androgen receptors, activating them and thereby altering the expression of genes and increasing protein synthesis. This builds new muscle without the harmful effects on prostate and other secondary sexual organs typical with anabolic steroids and prohormones.

Benefits of Using S4

S4 offers a range of benefits, including supporting muscle tissue growth and bone mineralization, reducing body fat and increasing muscle density and hardness, enhancing resistance and vascularization, contributing to muscle growth and preventing bone loss.

S4 can also help maintain and increase muscle mass during periods of fat loss (cutting). By reducing the activity of lipoprotein lipase, an enzyme that facilitates lipid accumulation, S4 promotes “fat burning effects.”

Dosage Details for S4

A protocol of 50 mg/day for 4-6 weeks is appropriate for cutting purposes for most users. However, some users may follow a 5-day-on, 2-day-off protocol wherein S4 is used for 5 consecutive days followed by a two-day break.

For “recomping,” or gaining muscle mass and losing fat simultaneously, 50-75 mg/day for 4-8 weeks is suggested, with calories kept just above the maintenance level. At least 30% of the calories should come from lean protein sources.

It is important to note that the half-life of S4 is approximately four hours, which recommends the daily dosage be spread into multiple administrations throughout the day.

Advantages of S4 over Other Supplements

S4 offers various advantages over other supplements, including a high oral bioavailability without liver damage, no need for supplements like milk thistle for the liver or substances for cholesterol control, and reduced swelling and other estrogenic effects. Furthermore, S4 does not require a long time between one cycle and the next, making its use more convenient and efficient.

It is always recommended to consult with a healthcare provider before beginning any new supplement regimen, including S4.
