    Sources of injectable Testosterone Undecanoate in the U.S? Compounders?

    Is injectable testosterone undecanoate available in the U.S (aka not clinic-only Aveed)? If so, who can make it? It vaguely appears that Empower may be able to make a mixed-ester combination? Beyond that, I see no way to procure this in the US. Does anyone have an ideas...

    Testosterone Undecanoate

    Someone has experience with Testosterone Undecanoate ester? Wikipedia says that this ester have 21 days half life, it is true? If so, would be a better choice for TRT, right? Injecting two times per month.

    Undecanoate split (NEBIDO/AVEED)

    Has anyone tried splitting NEBIDO shots into 3 and doing once a month? I seem to get HUGE spikes in Test, E2 and SHBG every time I get shot. Would this calm everything down a bit?
