Possible Benefits and Drawbacks of Methylene Blue

I’ve noticed a bit of ED. I’m assuming it has to do with the vasoconstriction?

Interesting as I have had the opposite effects , warm feeling in testicles and a “unrequested” erection that hung around for 15-30 min. 65yrs old no problems with sexual activity before MB use. Although I have had lower back pain and leg(hamstring) ache. Dosage was first time 10 drops in 8 oz cold water and 2nd 6 drops 8 oz water

Update … No dosing for 2 days.. back pain gone and…back to “normalcy” elsewhere…might try just 1 drop today in 8 oz water… Just to see as I felt less body aches in joints and stiffness , little more “awake”…other than lower back when dosing first times.
