So this is only my second order from MP for liquid tadalafil. The level of medicine once it settles seems to be about half of what my first bottle was, although I didn't look closely at the first one and its almost gone. Anyone else use this and have this experience? Hard to see so I drew a yellow line where the medicine level is at. I love it and works great but I will look elsewhere if this seems to be a common occurrence. Thanks, CS
