I don't know of any evidence for that and I think it is extremely unlikely.
There is a pharmaceutical that attempted to accomplish this: Andriol (testosterone undecanoate in oil-filled capsules.)
Andriol at 240 mg/day (1680 mg/week) might at best, being very optimistic, compare to 200 mg/week of injected testosterone ester.
That would be at best 12% bioavailability, and a better figure might be only half that. So let's say 6-12% as an estimate.
Cypionate or enanthate would have no reason to do better.
I don't think grapefruit juice would make a big difference because although CYP3A4, the enzyme that grapefruit juice inhibits, does metabolize testosterone, it is not at all a required step.
