S-4

S-4 (Andarine) is a Selective Androgen Receptor Modulator (SARM) that does not have androgenic activity in non-skeletal-muscle tissues. The physiological effects of S-4 on research subjects includes increased density and hardening of muscle fibre tissue, fat oxidisation and nutrient partitioning. The compound also has a mild effect on Oestrogen levels. This compound was designed for treatment of conditions such as muscle wasting, osteoporosis and benign prostatic hypertrophy, using the non-steroidal androgen antagonist bicalutamide as a lead compound. This makes S-4 an ideal candidate compound if your research is based around either muscle tissue hardening, fat oxidisation, bone density or a combination of all three. Physiological improvements of test subjects are considered very dry with zero water retention and a substantial improvement in the density of muscle fibre tissue. The Pro version of S-4 contains an "Absorb Core" base to improve bioavailability and to extend the half-life of the compound, making it one of the strongest and most efficient on the Research Compound market. S-4 is slightly suppressive so a light PCT is required for test subjects following administration of a course of this Compound. Recommended administration length is 8-12 weeks.
