    WHAT IS S22?

    AIias:  Ostarine and MK2866.

    S22 (Osterine) is a powerful (Selective Androgen Receptor Modulator) which is an anabolic compound created to build muscle for people suffering with muscle loss diseases. 
    It has shown to have very minimal side effects and very positive results
    These include:

    • Increased lean muscle mass
    • Increased fat loss
    • Increased bone density

    BIOV8 uses only premium pharmaceutical grade in all of our products.


    S22 / MK2866 (Ostarine)


    Selective Androgen Receptor Modulators provide patients with an alternative to using anabolic – androgenic steroids like testosterone. MK2866 peptide minimises the unwanted side effects that are commonly experienced when using androgen steroids, such as:

    • Aromatisation to estradiol
    • Conversion to di-hydro-testosterone (DHT) which can cause symptoms like hair loss

    Molecular Weight: 389.33

    What are the benefits of Mk2866?
    • Increased lean muscle mass
    • Increased fat loss
    • Increased bone density
    What are the effects?
    • Anabolic effect similar to testosterone
    • Less side effects experienced than high dose steroids, including prostate and cardiovascular outcomes
    • Not as liver toxic, unlike most oral steroids
    How does it work?

    By stimulating the androgen receptor, S22 can provide a qualitative similar therapeutic outcome to androgen therapy without any increase in androgen levels. S22 exert many of the same positive effects on muscle tissue as anabolic steroids like testosterone and can be administered in an injectable dosage form as well as orally, and are also not as liver toxic as most oral steroids. The anabolic effect has been clinically determined to be the same as testosterone. Bone mineral density is another benefit of using S22, where it has been shown to result in dose-dependent increases in bone mineral density and mechanical strength. > It is proposed that  MK2866 is three times stronger and more efficient than the most potent Testosterone-like steroid. >  MK2866 has been highly recommended as being an ideal peptide for andropause and should be used by all men once they hit 50 to restore testosterone levels. Optional / Highly Recommended Blood Testing for  MK2866: Though it is not mandatory in getting a script fulfilled with Peptide Clinics, the testing suggested for anyone interested in buying  MK2866 is available optionally. Being vigilant in your health goals, it is really in your best interest to draw the focus away from the ultimate visual gain you seek and take a moment to consider what is going on inside your body. Taking this step, you will be able to identify and control more readily your success.

    The tests suggested for MK2866 are:

    • SHBG
    • Estradiol
    • PSA Free and Total Testosterone

    Suggested Dosage:

    Inject: 0.25mL 1 x daily SUBQ injection. Immediately after training 5 out of 7 days. 

    Transdermal Cream: 1mL 1 x daily rubbed between forearms immediately after training 5 out of 7 days.

    Cycle duration : 4, 8 or 16 weeks.
