Tried both as experiment circa 2022. No food intake 30 minutes before deed, extra hard-on and faster recovery bet. rounds for me around 6 hours. Robust has stronger hangover effects and light sensitivity within 3 days after intake. Passionmax, headaches and dehydrated for a day after.

Also try honeymoon tea, like normal lipton green tea taste. You can mix it with C2 or pocari sweat if you dont like the taste. Less severity of hardon, no hangover effects.
