Buy S4 Andarine 25mg Tablets

S4, also known as Andarine, is a Selective Androgen Receptor Modulator (SARM) developed to exhibit tissue-selective androgen receptor modulation in myogenic and osseous sites. S4 binds selectively to androgen receptors, initiating anabolic transcriptional signaling pathways without strongly affecting other organs. It is considered less potent than other SARMs but is often studied for its balance between improvements in contractile performance metrics and minimal off-target pharmacodynamic responses. Andarine is strictly intended for research use only and is not approved for human or veterinary consumption.

How Does S4 Andarine Work?

S4 (Andarine) works by selectively binding to androgen receptors in skeletal muscle and bone,  activating biosynthetic cascades for muscle protein accumulation similar to testosterone. Once activated, these receptors initiate transcription of mTOR-regulated anabolic genes and osteogenic matrix turnover and mineralization. Unlike anabolic steroids, S4 exhibits negligible aromatase or 5α-reductase-mediated biotransformation, minimizing estrogenic or androgenic adverse events in experimental models in research models. Additionally, it shows partial agonist activity in certain tissues, meaning it can function as a partial agonist to modulate receptor response amplitude. This selective action allows for muscle and improvements in contractile performance metrics in experimental settings while potentially  limiting undesirable pharmacological responses seen with traditional hormones.
