Supplements can be useful but it’s generally only 10% of all your added effort put together. That’s why I stopped all supplements except for a little caffeine, creatine, and MCT oil for my gym workouts and rely more heavily on food than what a factory can put in a bottle and market as cutting edge technology.
My pe supplement stack is very simply… I just take 200 mg of caffeine as soon as I wake up with a glass of water right before pe. Now most guys stay away from caffeine because they fear it will hamper their erections but a little amount will actually increase adrenaline a little and give you the boost needed to have sex or pe. 200mg for me is a small dose for my bodyweight and size but others may only need 100mg or 50mg, which would be a small cup of coffee without milk or sugar, or 2 cups of green tea.
As far as a pe related diet, I have experimented with everything from bodybuilding diets when I wasn’t working out to vegan diets while performing pe. The only thing that worked to get my penis bigger and keep bodyfat levels the same or decrease them was quite simply a high protein diet (mostly chicken and fish with beef only once a week) , regular amounts of healthy fats from olive oil, mct oil, or some from the lean meats themselves (but never eaten any sooner than 2 hours before pe) and lower carbs from mostly high fiber or green vegetable sources (you’ll need some after pe but not much more than 10-20 grams so have an orange or something).
