    Natural Bodybuilding SARM Powder Andarine S4 GTX-007 High Purity CAS 401900-40-1

    Product Description:

    Selective androgen receptor modulators or SARMs are a novel class of androgen receptor ligands. They are intended to have the same kind of effects as androgenic drugs like anabolic steroids but be much more selective in their action, allowing them to be used for many more clinical indications than the relatively limited legitimate uses that anabolic steroids are currently approved for.

    S-4 is an experimental or investigation-stage proprietary SARM research chemical developed by GTx Inc for treatment of benign prostatic hypertrophy, muscle wasting, and osteoporosis. S-4 is considered a partial agonist of the androgen receptors in target tissue. S-4 has less pronounced anabolic and androgenic compared to other SARMs. In trials treating BPH induced in animal models, S-4 reduced prostate weight as effectively as finasteride and without producing any reduction in muscle mass or other side effects common with androgen receptor binding compounds. Gao et al suggest that by binding to androgen receptors, S-4 prevents DHT from binding and activating, but bypasses the expected anti-androgenic effects that would occur from occupying androgen receptors due to the fact that S-4 itself is a partial agonist of androgen receptors. S-4 has also been shown to prevent bone loss, reduce body fat, and improve muscle strength and body composition in orchidectomized and ovariectomized rats.


    S4 Andarine is an orally active partial agonist for androgen receptors. It is less potent in both anabolic and androgenic effects than other SARMs. In an animal model of benign prostatic hypertrophy, andarine was shown to reduce prostate weight with similar efficacy to finasteride, but without producing any reduction in muscle mass or anti-androgenic side effects.


    1. 1/3 as androgenic as testosterone in muscle tissue
    2. Anabolic at doses above 50mg
    3. Great for strength
    4. Great for muscle hardness
    5. Great for enhanced vascularity
    6. Great for endurance (aerobic or anaerobic)
    7. Accelerated fat loss above 50mg
    8. Joint healing effects
