Depends on your price range.


Magnesium

Citrate is perfectly fine. Just don't take two pills at once. Use the bottle up and next time buy a malate or glycine (depending on your goals, the latter, glycine, is best for relaxation, in which case you should take it before sleep.)

Nofap

Okay, so i could go on and debunk nofap and the science behind it, but that would waste both our time - because you're not doing nofap on the premise that it is scientific, you're doing it based on your own experience. And that is perfectly fine and valid (in this regard, I also recommend you not to mention yourbrainonporn when trying to convince anyone that has a high literacy in scientific studies. thats a really shitty site btw).

Brahmacharya is nofap in a way, yes, but there are some subtle differences. I do it because i do observe some energy being present when I do not do the deed. But this is entirely related to the deeper stages of meditation, and has nothing to do with any of the bullshit stuff you read on nofap about gaining social powers (I mean seriously how far on the autistic spectrum are these people?). Personally, masturbation does not make any difference for me in that regard.

Hope i am of help :)
