For me around 2 or 3 hours. That’s actually how I almost blew my dick up the first time I used it. After the first hour I got impatient and shot myself up again. The pain from a nonstop hard on is insane. I was two seconds away from going to the ER with a big purple hard on.
Takes the wife about an hour or so. It’s funny to cause you can literally sit and watch her starting to get hornier and hornier.
I have had guys tell me it’s taken them 4 hours to feel the effects. So I’d say anywhere from an hour to 4 hours for it to kick in. Trial and error until you get it right.
I will say the last batch of PT141 I bought was complete bullshit. We waited and waited and nothing. After 4 hours we took another shot and again nothing. That really pissed me off. Now I’m actually without a source for it. I won’t chance another bunk ass purchase with my last one.
