The dosage is insane. Inhibiting the breakdown of second messengers like cAMP and cGMP can have vast benefits, including sexual benefits. But you generally should not need a dose so large. 1,500-2,000 milligrams of horny goat weed is good, quality varies. Something that's 20% Icariin or higher is best. Pharma cGMP facilitators are much much more potent. I can't remember the exact equivalence, but I'm pretty sure sildenafil is like 80x more potent than Icariin. So you wouldn't need that much, like 2.5-5mgs of tadalafil would work. But I generally fail to see how this will increase "emotional closeness." This will just improve erection quality. I think peptide research like PT-141 or Oxytocin is more up the alley you're looking for. I don't think any of these substances are "Peat approved" or even generically bioenergetic friendly, so do your research thoroughly and accordingly. I do have a more nuanced approach towards nitric oxide, and I think it's obviously useful in certain scenarios. But from a sexual standpoint it's only so useful before getting diminishing returns elsewhere (like dangerous hypotension).
I see a lot of men striving to achieve that "teenage self" again. It's a valiant effort, but there's a reason few people ever succeed at this. Teenage sex drive isn't from nitric oxide or androgens. It's actually from an enhanced histaminergic tone with a lack of H3-H4 receptors. H2 (and to a slightly lesser extent H1)has a profoundly strong pro-libido effect, but in adults the autoreceptors (H3) and the H4 receptors prevent this from happening. The teenage brain still hasn't fully created all these networks yet. Dopaminergerc networks also form before serotonin. So a teenage brain is very high in pro-libido histamine receptors, dopamine receptors, and really low in anti-libido stuff like H3, H4, and serotonin.
