For optimal results you need to inject at least twice a week. Many inject EOD. When doing that, T levels will always be very steady and then there is no concern about what ester is fast and what is slow. And no need for propitiatory ester blends.

T eth has more T per mg and would provide more T that an equal dose of T cyp. But if you are adjusting T dose to achieve high normal FT or bio-T, then the dose simply gets increased. But most docs do not think that way.

T cyp will flow through a 0.5ml 0.5" #29 insulin syringe. [Do not use 1.0ml.]
