SARMS Ostarine UK

A snippet from our research library

  • A brief analysis of the SARM Ostarine use in humans

    Ostarine, a Selective Androgen Receptor Modulator, has gained popularity within the bodybuilding and fitness community; owing to its illicit use as a performance and image enhancing drug.

    Orgininally, ostarine was studied for the treatment of muscle wasting diseases, such as MS and HIV/AIDS. Currently, anabolic steroids are used for this purpose, but often cause unwanted physical and psychological side effects.

    Side effects of Ostarine use

    MK2866 can cause some degree of HPTA shutdown, but generally not on the level of drugs such as Testosterone. Users may have to include a Post Cycle Therapy (PCT) in their cycle of Ostarine as a precaution.

    Hypertension (High blood pressure) is another possible side effect, and it is commonly known that androgen use can use high blood pressure, this could be associated with the oedema (water retention) caused by androgens.

    Changes to libido are also common, because of the increased androgen activity as common with most SARMS UK

    Ostarine SARM side effects compared to AAS

    Steroids can cause a range of unwanted side effects in both male and female users. Ostarine is often seen as alternative to certain oral steroids, such as Anavar. MK8266 is not hepatotoxic, so it does not cause liver stress, which is often cited as being a one of the distinct advantages of SARMS over anabolic steroids.

    Hair loss is a common side effect of anabolic steroid use, this is cause by high levels of Dihydrotestosterone binding to the DHT receptors on the scalp. This side effect is most prominent in those who have genetically disposed to Male Pattern Baldness

    Ostarine and other SARMS in females

    It is generally recommended that women do not use highly androgenic steroids, because of the potential virilization effects this can cause. Ostarine is considered by many to be a powerful and safer alternative to this, because of it’s lack of androgen activity and high level of anabolic activity.

    Females will often experience a more potent anabolic effect compared to men, as females are much more sensitive to anabolic hormones then men.

    Ostarine common dosing


    25mg/day for 12 weeks


    12.5mg/day for 8-12 weeks

    Ostarine can be used for longer periods than this, however, it is a good idea to give the body a break from exogenous hormones and other performance enhancing related drugs

    Estrogen, joints and bio-availability of the SARM Ostarine

    Ostarine does not aromatise into estrogen, so it does not require any kind of estrogen management. Side effects such as Gynocomastia are not possible from using this SARM.

    Ostarine and joint protection

    Ostarine has been clinically indicated in the treatment of Osteoporosis and other pharmaceutical drugs which cause reduced bone density. MK2866 causes anabolic activity in both muscle and bone, reduces the risk of injury and improving healing on injury.

    SARMS and Bioavailability of Ostarine

    Ostarine is highly orally bioavailable, meaning it can be acceptably digested by the human digestive system. This was a highly sought after attribute for a future drug for Testosterone or androgenic replacement therapy, to reduce the use of intramuscular injections.

    Conclusions of Ostarine side effects

    Ostarine is generally considered to be safe, but being a investigatory drug, if people decide to self administer this drug, it would be wise to seek medical supervision and have regular blood work.
