Used them both already, i rather use the Black Ant. Works 30 min after taking it. this stuff stays in your body for 72 hours. Never had any problems taking it. Took it when going to a nude beach and was hard for the whole time i was there.
I am also uncut and always used to do stretches with the skin but over time with practice you will be able do stretch without the skin,start off slow and you will get there.
