100 mg of nandrolone plus 100 mg of testosterone if your hematocrit and HDL are OK after 6 weeks (hematocrit under 54, HDL over 40). Some guys use 100 N plus 150 T. The length of the nandrolone “cycle” is dependent on how well both variables behave at those low doses. Most guys do well unless they have apnea, they smoke, or have low HDL before starting.
You will hear arguments about nandrolone to testosterone dose ratio on ExcelMale and other sites from guys who spread the “deca dick” myth. All anabolics shut down T and they all need to be used with TRT. You will also hear from some guys who spread misinformation about nandrolone used to replace T. I have researched and read about nandrolone for over 30 years and I am tired of all the misinformation. You will also find posts here that say it’s bad for men since it has similarities to progesterone.
