I have a prescription for Yohimbine. It cost $15 for 100 5.4mg pills.
The Rx version is much more stable, tolerable and cheaper than any “Herbal” supplement. No significant side effects - no crazy headaches, no incredible palpitations, no sweats.
It can make you sleepless if you take too much, and you build a tolerance to it quickly. You can’t take it consistently and expect the same results. It doesn’t work for everyone.
But before Viagra, it was commonly prescribed for impotence. I take it to overcome anorgasmia, but it definitely can put some more lead in your pencil. It intensifies orgasm, and may reduce mean-time-to-shoot.
If your doc won’t write you a scrip for Yohimbine, it’s time to find a new doc. Good, competent urologists and andrologists are very rare, and it may take a couple years to find a good one. Don’t wait until you need one to start the search.
