If you are hypogonadal or low-T you normally will feel like you are living in slow motion.Once bumped into the mid to upper range you start feeling much better.
Stewies journal posted showed that 125 mgs per week put the subjects into mid/normal range.The next dose 300mg put the subjects up out of range by too much.A good doc would not keep a patient at that dose for HRT.
Roughly you produce between 50-75 mgs per week,roughly.So 100 mgs of enth or cyp minus the ester is 72 mgs which is at the top of what you produce naturally.Some need 150 mg(which is 108 mgs minus ester).****That about double if your producing around 50 mgs naturally.******Some need 200 mgs (144 minus ester) to get into normal range.
