Get some sort of Dopamine agonist < this I believe is most responsible for erections and quality. Perhaps the ratio is 60% TEstosterone < including DHT in that TEst category, and some estrogen < which is needed for boners as well. Then about 40% dopamine. Infact if you're dopamine is high and you're fucking you can get rid of your refractory period. Theres a Bodybuilding peptide called Cabergoline stops prolactin < which kills your boners so you don't get priapism and up boosts Dopamine. Or get Kratom. Don't take alot.
