I have a situation and was curious what you guys think. I am 36 years old and have worked out for several years. As of late I have lost energy and endurance in the gym. I have always been a good athlete, but as of late I have lost a step or two. I have been thinking of trying test cyp, but have been scared to due to the possibilty of failing a drug test. Wanted to check on test replacement therapy but my test levels are normal. I was told by a guy in the gym to try Mass Tabs by IDS. He said take them for a few weeks and then lay off of them for a couple. He said if I did this my test levels would drop temporarily and that my levels would be low enough for test replacement therapy. I was wondering if this is a good idea or if it would even work. Thanks in advance for the help....
