I dunno, Pumpkin seed is a good source of zinc and healthy fats to be sure. Somewhere I read Peter North eats them by the ton, but I can’t say for sure as we’ve never hung out. Arginine, which is the main ingredient in pre-workout NO2 boosters is good for erection strength. Products like No-explode, controlled labs “White Flood”, and Gaspari nutrition’s “Superpump 250 all come to mind, but any kind of Arginine will work. You may be able to find something out there in tablet form that is cheaper and as effective as these brand name products. I should really buy some pumpkin seed next time I’m at the store. They’re good and good for you, and cheaper than arginine, which I take anyways for weight lifting. You can also buy pumpkin seed oil in capsules at most supplement stores. I found it increased pre-cum, but that will differ for different people.
