Drugs and Suppplements in Masters

With the apparent increase in use of supplements as human growth hormone, testosterone, HGH, EPO and IGF-1 in sports (particularly cycling) during the last decade, I wonder if their use has managed to leak over to masters events...... including swimming. Seems silly to me that anyone would use hardcore muscle building agents as these in a setting such as masters so late in life. Is it worth implementing drug testing, or does it really matter in the end....... after all its just masters. John Smith >•´¯`•.¸ > ¸.•´¯`•.. )º))))))))))))))><
