Hey Dylan I have been hearing so msny different things about testosterone ester that I do not know what to believe anymore. I have read and heard that it has a half life of 16 days and you o my need one injection every 2 weeks. I have also heard that the half life is 53 days and that a 4ml injection of 1000mg once every 10 weeks is needed. Do you know what the half life is on this ester and how often at what mg would be best for TRT? I've been on so many forums and heard so many different things. Also is this best for TRT?
