Stacking Ed Medications?
I am wondering if anyone has stacked any of the three ED medicines together at once. I have seen some research chemical sites selling combos, like a viagra/cialis combo (50mg sildenafil and 25mg tadalafil per ml) and I also saw a viagra/cialis/levitra combo (50mg sildenafil, 25mg tadalafil, 10mg vardenafil per ml). Do you think these are safe? Has anyone tried any such combination?
