Yes @ninjamike... I have used fenugreek in the past, but it was along with other herbs in a cocktail of sorts - which worked, by the way... so I'm not sure how well it works alone. I'll try doing that one day :>)

I should have included the fact that beets boost nitric oxide (It was written in the wee hours and I grew tired eyed) I use it in powdered form as well (very convenient that way) I've also used betaine or 'bio-identical'??? bought in small bulk from a bio-chemical company some years back.

L-citrulline is a great amino acid to boost nitric acid in the blood stream. Converts to L-arginine, if I remember correctly to open up arteries. Provides for a good pump too at the gym; or the bedroom...😏
