You should carefully weigh up the risks and benefits of using any supplement, injection or tablet before you take it. It is also particularly vital to be aware of any further risks that may be present by using black market, unregulated products.
All of these substances are also banned in many professional sports and bodybuilding competitions. Using these substances can lead to disqualification from certain sports, as seen when an Iraqi bodybuilder entering Qatar for a competition was found in possession of anabolic steroids and was disqualified from the event before it had even started (12).
These substances are not new and will not disappear overnight, but by educating people about their dangers and long term effects, it is possible to minimise the damaging health effects they can cause.
If you are worried about any symptoms you may be experiencing, or have any further questions about performance enhancing drugs, you should speak to a qualified doctor about them.
