I take HGW when I feel like it, although I’ve taken it daily over time since starting to take it about 15 or so years ago. I take Swanson brand it says to take it between meals, so I do. I can’t tell if it does more for me prior to sex/cumming or if just having it in my system during the day/night and taking it every day so its always in my system is beneficial or more so than taking it specifically before I get off. I do know it makes me more horny, easier to get aroused, sensations feel a little more strongly and are felt a bit more deeply, and they make my wife feel good too ;) I take Maca as well and also take it during the day, morning and evening, and its always in my system. I kind of feel like the brands that specify “take 1-2 hours before sexual activity” are just trying to label it as a sex aid even harder and more forcefully. When you buy the individual ingredients from reputable herbal supplement shops or sites, they just specify whether to take it with water only or with food too, and when, like morning or three times a day, etc..
you just gotta take it with a plan and chart how it works, how does it make you feel, are you getting the benefits you bought it for, stuff like that. Supplement use is trial and error, testing, experimentation, and finally after enough testing has been done you can dial in and lock down a supplement regime.
