Your question was reactions.
Blood levels and binding domains are two different things. Testosterone regardless of the ester will bind to three different binding sites of the androgen receptor.
Cell surface membrane AR receptor ---cytoplasm which exerts nongenomic actions. There's no translocation to the nuclear receptor from this binding domain, only during dimerization will this occur. Cell surface membrane receptors are G protein-coupled receptors, which are subcategorized separately from nuclear receptor superfamily. Main differences between these two: cell membrane receptor (extracellular) facilitates in nongenomic actions as the nuclear receptor (intracellular) facilitates in genomic actions.
N-terminal domain which translocates androgen response elements either genomic or nongenomic actions. HSP 70/90 (heat shock proteins) give way for im/proper protein folding.
Nuclear receptor domain which gives way for instructions of mRNA translation to promote DNA-CAGn expression, genomically.
All three domains orchestrate in concert with each other through conformational changes of translation, transduction and transcription. After the cell surface membrane AR binding, mRNA translation, ect the provided ligand information that translocates to the nucleus. Then the dimerized receptors bind to the androgen response elements (cytoplasm AR and nuclei AR), which are specific to your DNA-CAGn repeat length sequences located in promoters of target genes, resulting in transcription of the target genes.
Again, the ester won't change the molecular/ cellular dynamics. The only difference is cleavage rate (hydrolysis) of the molecule from the ester.
