I dont know about PN but these thing I know FOR SURE will increase ur cumshot distance,amount,thickness I have listed them into 2 groups
1-with no side effects:
-Zinc 30mg
-lechtiin(sp*?)
-l-arginine 2g spread across the day
-vitamin C 15grams or so...(helps with erection strength and cum from peronsal experience)
-Pc exercises
-ROP(yet to be determined)
-more protein intake(whey/milk shakes are good)
-1 gallon a day water intake
-prostate massage
-increasing the arousal (remember when u came while looking at some korny ass model when u were young?? remember when u got the best bj/hj ever how much more u came??
)
-ZMA(if ur gonna take this drop the zinc listed above since too much can cause copper defeciency if u are taking more than 30-40mg u need to supplement with copper but too much can lower ur immune system...remember to add more the more sexually active u are..u lose approx 5 mg each time u cum)
-ball massage
-cool weather
-jacking off to the point of ejac then stopping done 1 hr or so before the event dunno if this affects ur duration of cummin or even the volume but people say it works
-abstain from cumming for 2-3 days or more if u wanna impress..IMO after a week all results are the same
2-with side effects
-Nolvade
increases sperm count and thickness not amount)
-clomid
-hcg
-testosterone
Hope this helps some1
