Here is something else. In women, Vitex reduces excess prolactin which reduces breast cancer risk.

https:///pmc/articles/PMC2752044/ Vitexins, nature-derived lignan compounds, induce apoptosis and suppress tumor growth. A mixture of Vitexins EVn-50 and purified Vitexin compound VB1 have cytotoxic effect on breast, prostate, and ovarian cancer cells and induces apoptosis with cleavage in PARP protein, up-regulation of Bax, and down-regulation of Bcl-2. This induction of apoptosis seems to be mediated by activation of caspases because inhibition of caspases activity significantly reduced induced apoptosis. We demonstrated a broad antitumor activity of EVn-50 on seven tumor xenograft models including breast, prostate, liver, and cervical cancers. Vitexin is a class of nature lignan compounds, whose action and anticancer effect is mediated by the mechanisms different from the classical lignans. Vitexin induced antitumor effect and cytotoxic activity is exerted through proapoptotic process, which is mediated by a decreased Bcl-2/Bax ratio and activation of caspases.
https:///pubmed/12520164 “Cytotoxicity and apoptotic inducibility of Vitex agnus-castus fruit extract in cultured human normal and cancer cells and effect on growth” Cytotoxicity of the extract against human uterine cervical canal fibroblast, human fibroblast (HE-21), ovarian cancer (MC-7), cervical carcinoma (SKG-3A), gastric signet ring carcinoma (KATO-111), colon carcinoma (COLO201), and small cell lung carcinoma (LU-134-A-H) cells was examined. It is concluded that the cytotoxi activity of Vitex extract may be attributed to the effect on cell growth, that cell death occurs through apoptosis, and that this apoptotic cell death may be attributed to increased intracellular oxidation by Vitex extract treatment.
The two steroids are really interchangeable, and cypionate is not at all superior. Both are long acting oil-based injectables, which will keep testosterone levels sufficiently elevated for approximately two weeks. Enanthate may be slightly better in terms of testosterone release, as this ester is one carbon atom lighter than cypionate (remember the ester is calculated in the steroids total milligram weight). The difference is so insignificant however that no one can rightly claim it to be noticeable (we are maybe talking a few milligrams per shot).
Due to membrane-bound CYP3A4's natural propensity to conglomerate, it has historically been difficult to study drug binding in both solution and on surfaces. Co-crystallization is difficult since the substrates tend to have a low Kd (between 5-150 μM) and low solubility in aqueous solutions.  A successful strategy in isolating the bound enzyme is the functional stabilization of monomeric CYP3A4 on Ag nanoparticles produced from nanosphere lithography and analyzed via localized surface plasmon resonance spectroscopy ( LSPR ).  These analyses can be used as a high-sensitivity assay of drug binding, and may become integral in further high-throughput assays utilized in initial drug discovery testing. In addition to LSPR, CYP3A4-Nanodisc complexes have been found helpful in other applications including solid-state NMR , redox potentiometry, and steady-state enzyme kinetics .
