This one takes about an hour to kick in with peak efficacy coming between 8 and 24 hours after using. But with quite a lot of staying power into the 3rd day after using. As with prescription ED treatment, I only take this when I'm looking to go multiple times in a short amount of time. This is excellent for recovery and a quick rebound. As some other reviewers mentioned, this almost works too well in that once taken, you're likely to rise to the occasion for any old thing that comes to mind or walks on by...which is why I don't take this on a regular, saving it for when I need to rebound many times in a short amount of time. I'm middle age and don't necessarily want to develop erections for no reason while in public. It's just not a good look...especially at the gym. Other than working too well the side effects are similar to the prescription ED treatment: fairly pronounced facial flushing (for me only last a few hours), mild headache (but not every time I take it---drinking lots of fluids seems to help), and mild nasal congestion. Wish this came in a tablet form that I could cut in half as a half dose seems to be more what I need...just the right of rebound power without aching throbbing erections that need to be taken care of before I can return to my non sex life. As with the prescription ED treatment, I find it effective into the 3rd day but by the 3rd day, it seems to act as somewhat like a delayed climax pill in that it takes me much longer to reach orgasm...which can be fun but something I remember before trying to have a quickie when I'm on day 3 of this pill. Day 3 is definitely for long extended sessions.

I don’t always leave a review but thought I would just so others would know that it does work. Was having a little problem downstairs because of a lot of stress and being stuck in my head. Looked up things that could help so I bought Horny Goat Weed and Korean Panax Ginseng, but that’s stuff is apparently “snake oil” and didn’t do or change a thing. So I looked up other things and come across The Blue Pill, so I took a chance on it...and omg it works! Some reviews I seen where some got headaches but I did not. I did however feel like I drank one too many Mountain Dews but it still wasn’t bad. Could definitely feel a difference downstairs and he come to life not only once but stood up for round 2 just 10 minutes later.. and again the next morning!.. 20 hours after taking, I can still tell I’d be able to take her for a spin easily.. hmm maybe I will!😎😍.. sibif you’re looking for something to help, I advise yo give these a try. $250 for 10 boxes seemed like an expensive gamble but I’m so glad I did.
