    German Pharmaceuticals - Ostamax


    Ostamax is one of our best selling muscle building supplements! Ostamax is an incredibly versatile product due to its ability to produce exceptional results during both cutting and bulking cycles. By supplementing Ostamax you will be augmenting your hormonal activity to favour muscle growth, as well as a host of other benefits. Ostamax is perfect for those who are new to muscle-building supplements or anyone who wants to increase muscle mass quickly. 

    The Benefits of Ostamax

    • Increased lean muscle mass
    • Accelerated fat loss
    • Influxes in strength
    • Greater sense of well-being
    • Increased energy
    • Increased vascularity 

    How Ostamax works

    Ostamax was originally used to treat osteoporosis, but it quickly became recognised for its ability to enhance athletic performance and improve body composition. Ostamax promotes muscle growth by mimicking test (1), enabling a greater uptake of test into muscles, whilst avoiding the extent of side effects associated with anabolic steroids (2). Clinical studies have shown the compound in Ostamax to increase lean muscle mass whilst decreasing fat mass (3). 


    Most users begin to see results within a couple of weeks, usually in the form of increased strength and improved recovery rates, allowing you to train harder with reduced delayed on-set muscle soreness. As you progress through your cycle you will likely notice decreased fat mass, increased vascularity and increased muscle mass. It is also common for users to report enhanced cardiovascular fitness and energy levels. 

    How to take Ostamax

    Beginners: Take 2 caps daily (20mg) for 12 weeks.

    Advanced users: Take 3 caps daily (30mg) for 8 weeks.

    As Ostamax has a 24-hour half life, you can take the full dose at one time, as dosages do not need to be split.

    Supporting information & supplements

    Post-cycle therapy (PCT) is strongly advised after using Ostamax as suppression can occur, especially when used at higher doses. For PCT we advise either German Pharma Ultimate PCT or Pure Labs Clomadex. These products will restore hormonal harmony, reduce risk of any potential side effects and help you retain the gains you have achieved.

    As Ostamax is non-methylated it will not damage liver cells, however we do recommend an on-cycle support, such as Pure Labs Milk Thistle to reduce any unwanted side effects whilst taking Ostamax. 

    To support muscle growth and development, and to utilise Ostamax optimally, adequate protein intake is helpful. PNI Pure Protein Advanced provides its users with 23g of protein whilst containing just 2g of carbohydrates and 0.5g of fat, making it an easy fit for your targeting macro intake. PNI Pure Protein Advanced is also lactose and gluten free making it incredibly easy to digest and doesn’t cause bloating.
