EQ could be affected by improved circulation through means other than NO. I don't know if herbs actually raise T because I don't have labs to prove it, but some can give me symptoms of that like increased strength, harder muscles, deeper voice, acne, etc.Can erection quality be effected more by Horny Goat Weed Icariin, slash Nitric Oxide Boosters ? Rather than stuff purported to raise T ? I’m not convinced these herbs raise T anyway
