the average adult male produces the equivalent of approximately 7mg per day of testosterone, which would be 91mg every 13 days. when you factor in that 75mg of Testosterone Cypionate is not pure test, but rather part of the 75mg will be ester, you are suppressing your natural test production to use a much lower level than you should have naturally. even if placed on TRT through a doc that is a rather modest dose, I would consider a second opinion.
