Andarine S4 25 mg, 60 caps

Andarine (S4) – 25 mg, 60 Capsules

Chemical Name: Andarine – S4
Molecular Formula: C₁₉H₁₈F₃N₃O₆
Compound Class: Selective Androgen Receptor Modulator (SARM) – Acetanilide Derivative

Product Overview

Andarine, also known as S4, is a potent and selective androgen receptor modulator (SARM) originally developed for the treatment of muscle wasting, osteoporosis, and benign prostatic hypertrophy. Structurally, it is part of the acetanilide family, which includes organic compounds featuring an acetamide group conjugated to a phenyl ring—a key factor in its high receptor selectivity and bioavailability.

Each capsule contains a high-potency dose of 25 mg of Andarine, with 60 capsules per bottle, providing a reliable and consistent format for research involving muscle development, fat loss, and bone health.

Mechanism of Action

Andarine functions by binding selectively to androgen receptors in muscle and bone tissues, simulating the anabolic effects of testosterone without the unwanted conversion to estrogen or DHT. It enhances muscle hardness, promotes fat oxidation, and may help preserve lean body mass during calorie-deficient conditions. Unlike traditional anabolic steroids, S4 does not cause significant suppression of natural hormone production or liver toxicity at standard research doses.
