Thanks for that reply.... Much appreciated. I have been doing X3 a week. IM ... Decided to try daily slightly more weekly amount doing sub q . Trying to boost libido ...Testosterone enanthate can certainly be used daily. However, I don't think most guys are going to notice much difference between daily and EOD injections at the same weekly total. The apparent half-life is long enough that the serum variations with EOD are already pretty muted. When I was using enanthate EOD my lab tests could not distinguish between measurements made immediately pre-injection and those made the day before/after the injection days. There may be exceptions in the other direction. One guy is reporting large drops in serum testosterone even with daily injections. If the results are accurate then they imply a much faster rate of absorption—and shorter half-life—than is typical.
