Helps is relative. You spend a bunch of money to get bit more benefit? Not really worth it.
If you want instant bigger wood, try the NOX2 caps, they seem to really work for enhancing circulation to the penis, more blood = bigger erection. Or without supps, eat more foods containing l-arginine, such as eggs, meat and nuts.
I think this effect is entirely what the penis pill industry is built on. Your dick doesn’t really get bigger, it’s just a higher quality erection, so it is perceived as bigger, but no growth occured, just maximizing the potential of what you already have.
Aside from that, eat adequate protein based on your LBM and activity levels, take 6 grams of fish oil caps daily, quit smoking, exercise, blah blah blah…
