“Sorry but I have not heard of many men gaining an inch in 3 months, rubbish.”
I gained 1.5” in 6 months, and with the most half-ass routine you can imagine.
The results regarding ejactulation are surely due to testosterone levels. When we ejaculate, testosterone levels are decreased (although not STRAIGHT after), and it takes them over 24 hours to recover to baseline levels.
Lower testosterone means less frequent erections (probably less night time wood as well) and less tissue growth (muscle growth anyway). The day of/after a PE session is when we would need the greatest frequency of erections, so that fresh blood is constantly being supplied to the recovering tissues.
Also, abstaining ejaculation for 7 days results in testosterone peaks of +10%, +25% and +45% (on average) on the 5th, 6th and 7th days respectively. More testosterone means better gains…
As for PE pills, they may lead to increased testosterone levels, but I know too little of them to really comment in that respect. And then there’s the phenomenon of the PLACEBO EFFECT. Maybe pill users gained more becuase they believed they would gain more (ever seen Space Jam? :) )
