S-4 (Andarine) Capsules

Brief Intro

S-4 (Andarine) Capsules contain a selective androgen receptor modulator (SARM) known for its high affinity and specificity for androgen receptors (ARs). Andarine (developmental code names GTx-007, S-4) was developed for conditions such as muscle wasting, osteoporosis, and benign prostatic hyperplasia (BPH). It exhibits tissue-selective activation, promoting muscle and bone growth while minimizing systemic side effects. Though clinical development has been discontinued in favor of related compounds, Andarine remains popular for research purposes. These capsules are intended strictly for laboratory research and are not for human consumption125.

Intended Use

S-4 (Andarine) Capsules are intended strictly for laboratory research, including pharmacological and biochemical studies on androgen receptor modulation, muscle growth, bone density, and related therapeutic applications. They are not for human consumption or clinical use156.

Packaging & Shipping

These capsules are securely packaged and shipped discreetly with tracking. Typical delivery times are 24-72 hours within the USA and up to 5 days internationally, depending on destination. Shipping fees are calculated at checkout based on location.

Legal & Compliance Disclaimer

All products are sold for research purposes only and are not intended for human consumption. Customers must verify the legal status of Andarine (S-4) in their jurisdiction before ordering. The vendor reserves the right to accept or decline orders based on intended use14.

Dosage and use

Use 50mg per day throughout the cycle. This is equivalent to two capsules. The recommended cycle is 8 to 12 weeks.

This SARM can be combined with other compounds and can be used during cutting and bulking.

What are SARMs?

SARMs are Selective Androgen Receptor Modulators. Put simply, these substances can tell your cells that they need to, for example, create more muscle mass or break down more fat. Each SARM has a different effect, allowing you to achieve very targeted aesthetic and physical goals. And that without experiencing unpleasant side effects such as hair loss, acne and liver damage.
