Vasodilators vs. vasoconstrictors

There are several drugs, some benign and legal and some dangerous and illegal, which fall into either of those categories.

The most easily available are alcohol (dilator), coffee (constrictor) and cigarettes (constrictor).

What can be said in principle about their effect on gains?

Can a dilator rather than a constrictor affect gains, or does neither drug type do a thing?

What puzzles me quite a bit, is my experience with Ritalin/meth. You see, in my youth I abused Ritalin a few times and excessively masturbated for some 24 hours in a single sitting with some 12 hours of erection and 12 hours entirely flaccid. As a result, the penis becomes extremely swollen for a week and looks monstrously ugly, 3 times enlarged and swollen. You can’t even urinate without a straw anymore, and always wonder if you busted it for good this time.

What is phenomenal is, that I did this only 2-3 times in my youth and each time it lead to really huge gains in girth. Before the 2nd time or so, the right corpus cavernosum (where the finger press harder when wanking) wasn’t really larger than the left one. I remember that very accurately. Then it grew to maybe 125% the size of the left one from just wanking on stimulants *one single time*, and that might be 150% of the original thickness I am not sure.

I also masturbated on meth when older, but I couldn’t observe such phenomenal results anymore.

So, really if I had not made those experiences I would believe that just beating it to death while on super-potent vasoconstrictors might do a huge deal of long-term damage. But really, it seemed to just be the magic trick that we are all after here.

Could topical vasoconstrictors (as e.g. Found in nasal spray) be a safe alternative?

What is your take on the topic?

The vasoconstrictors or dilators effect will not be localized. It can really cause you more harm than good. Just do PE the right way.

Given that either constrictor or dilator really would increase gains, what is the harm in drinking a strong cup of coffee or a glass of wine before PE?

Also, I am a light smoker. I try to avoid smoking cigarettes just before PE, but maybe the opposite would be better.

I am not sure how much the effects of topical creams really remain localized. There is at least some spread of the drug against the natural direction of blood flow into just the surrounding tissue. I believe it depends on the drug. With lidocaine for example, you can literally feel were it is going.
