Buy S-4 (Andarine) Capsules for Lean Muscle Growth & Fat Reduction with Discreet Worldwide Shipping
What is S-4 (Andarine)?
S-4, also known as Andarine, is a selective androgen receptor modulator (SARM) developed to mimic the muscle-building and fat-burning properties of anabolic steroids — but with far fewer side effects. Originally researched for treating muscle wasting and osteoporosis, S-4 has gained recognition for its strong anabolic effects and selectivity for muscle and bone tissues.
Each capsule from Peptide Online Store contains pure Andarine S-4 in a precisely measured dose, ensuring optimal accuracy and consistency for research applications.
How Does S-4 (Andarine) Work in the Body?
S-4 (Andarine) binds specifically to androgen receptors in muscle and bone cells. By activating these receptors, it triggers an increase in protein synthesis, nitrogen retention, and muscle density, while simultaneously promoting lipid oxidation (fat breakdown).
Unlike traditional anabolic steroids, S-4 does not convert to DHT (dihydrotestosterone) or estrogen, minimizing side effects like water retention or hormonal imbalance. This makes it ideal for cutting and recomposition research studies.

Dosage & Usage Guidelines
For research purposes, S-4 is often studied in doses ranging from 25mg to 50mg per day, depending on study parameters.
It is commonly administered in split doses (morning and evening) due to its short half-life of approximately 4 hours.
Note: S-4 (Andarine) is strictly for laboratory research use only. It is not intended for human consumption or medical use.
Safety, Side Effects & Precautions
While S-4 has demonstrated strong selectivity, some dose-dependent visual side effects have been observed in studies, including mild yellow tinting of vision and night-vision difficulty, typically reversible upon discontinuation.
No evidence suggests liver toxicity or severe hormonal suppression at moderate research doses, but post-research monitoring is advised.
Always handle the compound with appropriate protective equipment in a controlled laboratory environment.
