I’ve experimented with a lot of these brands over the years - some are worthless, others worked fairly well. Lots of pills claim perm increases and that’s pure junk - no pill can do that. I primarily looked for pills that improved cum volume, like Ejaculoid, Ogoplex and Semenax (even though I have big loads already, I’m greedy and want bigger) - but I have tried 3 or 4 that targeted EQ. By far the absolute best one I ever came across was called Levitrix. It’s no longer sold online but wow - talk about iron! If you can find that one, it’s well worth the money. I’ve read that Xtenze works fairly well but never bothered to try it. Male Extra is good too (got a buttload of them that came with an extender order) but it takes a while to notice the difference.
If you want to go a more natural route with supplements, HGW and Maca are a solid combination. L-Citruline works well too but over time - you have to build it up in your system.
