There are no ED ...... that address a "more potent ejaculation."
The tadalafil and PT-141 have a combined effect, mostly circulatory, that increase the firmness of an erection. Although clinical evidence is insufficient, PT-141 appears to increase sensitivity, and enhance erectile response. The oxytocin increases the neuro-emotional response.
Ejaculate potency (total volume, ejaculatory pressure) is much more complex. There are diet and training regimens that can improve this, but not many ...... that truly work to do so.
