You might consider testosterone undecanoate. You could inject that every two weeks and still have much less variation in serum testosterone. The caveat is that totally steady testosterone is also somewhat unnatural. If that turned out to be a problem then you could even go with monthly injections. That would still be only one half-life — versus your current two half-lives — so you could maintain your levels in a physiological range while still seeing some variation.That is an awesome chart, may have to reevaluate my protocol.
After 20+ years, honestly, I am just tired of the jabs so I try to minimize them. My highest post stick has been 1,200 ng/dl and the lowest day before the stick is 480 ng/dl
