I bought some 5htp in the past because it seemed to me the only acceptable way to manage depression without doing harm. I didn’t use it much however so I cannot tell anything about my experience.
In time I understood that it’s far better to get a good life. Have friends, lough, love, amuse with sports you like, train good habits, get sunlight and all that stuff. No cigarettes and alcohol, this is very important and withdrawing them can really boost you: it might take some time to get better though, weeks, maybe a couple months, that is the approximate time necessary for nicotinic receptors to get back to basal levels. Cigarettes and alcohol can really keep you down. It’s not easy to do all of that with pfs but results will come, at least on the mood and general wellbeing and energies, as long as you work on it and do them consistently. These things are much more powerful than a stupid substance that you inoculate in your body which is far too complicated to be well controlled by one single molecule itself. Oh and well you can’t feel well if you think about your penis all the time. Problems with it need to be accepted to a managable extent.
I agree however that without a bit of scientific knowledge about the body, it might be hard to understand how to direct your priorities. I’m into biology and medical research so it’s easier for me to comprehend what to do about myself, or at least i believe so ahah.
