All Knight Rx Overview

All Knight Rx is a male enhancement supplement that you take shortly before sexual activity to increase your libido, give you thicker, harder erections, increase your energy and stamina, and recover faster after finishing time after time after time. All Knight Rx makes two significant claims as selling points. One is that because it’s all natural there are no side effects. The other is that it can last for up to 5 days. The long lasting claim is unique so we decided to take a closer look to see if we can determine how well and how long All Knight Rx works.

All Knight Rx ReviewAll Knight Rx Ingredients and How They Work

Several pages, including the ingredients page, on the All Knight Rxwebsite are not currently functioning. We were, however, able to find the necessary information from other sources. Hopefully, they are credible. If our source is to be believed, the formula includes such herbal ingredients as:

  • Tribulus Terrestris to help increase the amount of testosterone in the body.
  • L-Arginine and Yohimbe to improve blood flow to the penis for better, harder, longer-lasting erections.
  • Damiana and Maca to improve libido.
  • Guarana (caffeine) to increase energy and mood.
  • Vitamins B12, C, and D-3 for energy, health, and immune system support.
  • Zinc to help facilitate the body’s production of testosterone.
  • An additional secret proprietary blend.

The recommended dose is one pill every 2 to 5 days or before sexual activity. They claim it can work up to 5 days, but that 3 days is the average. We don’t see anything in the ingredients list that would cause All Knight Rx to last longer than your typical Viagra alternative.

All Knight Rx Pros and Cons

Advantages of All Knight Rx

  • There’s no commitment involved.
  • There are some positive All Knight Rx reviews from customers who’ve found it to help.
  • The ingredients are all natural.

Disadvantages of All Knight Rx

  • It contains Yohimbe which the FDA recommends against using. It may cause serious side effects, especially with long term use.
  • It can be expensive.
  • Some All Knight Rx reviews indicate that it didn’t work, but did prevent the users from sleeping.

Where to Buy

Right now, with the website not fully functional, you can buy All Knight Rx through Amazon. One pill is selling for $4.95 while 2 pills go for $8. A money back guarantee is mentioned, but not fully explained, so you might not be able to count on that.


After comparing the two particular claims made by All Knight Rx with the ingredients and reviews, we have to come to the conclusion that All Knight Rx is really nothing special. Due to the Yohimbe, it may indeed cause side effects, and serious ones at that. And there’s nothing in the formula to explain why All Knight Rx would last up to 5 days. Add to that the amount caffeine and yohimbe, and it seems like the only thing All Knight Rx will keep up all night is you, and not in a good way.

Bought the 1750 pill at a local sex shop. I\'d say my normal libido and performance are below average in general, and... Holy hell.  Kicked in around 20 minutes with major flushing and stuffed sinuses (like cialis). Sitting on the couch for the next hour or so, I got a major erection which soon chilled out and gave way to a steady dribble of pre-cum.  Was planning on watching a porn but that didn\'t happen. The stuff gave me diarrhea, so I went to relieve myself. Saw my Fleshlight and got a bright idea...

Ended up in bed with it and an amazing hard on.  It was a very steady, really intensely pleasurable experience, warm all over and aggressive. I had a huge orgasm in 30min or so that even felt like it continued a few seconds longer than normal.  Stayed hard through the clean-up and went back to playing PS4. About 2hrs into it, got hit with a wave of anxiety... Felt like a mini panic attack. Calmed myself down.  Started noticing the muscles in my jaws tensing up as well as the back of my neck. I sat with these waves of anxiety for a bit, then decided to walk around a bit.

That lead to another masturbation session, even stronger orgasm (I never go more than once in a day).  Started getting the chills so put on a coat. Sat on the couch bouncing my legs constantly because if felt like it relieved the anxiety.  Had to get up again and walk around, got some hot water to sip on, sat back down. The anxiety/jittery waves lasted about 4 hours and I\'m just now starting to wind down.  Was getting worried for a minute. This was all with zero alcohol and took it with food (won\'t do that next time; mild queasiness).

Assuming this crap stops here shortly, I\'ll try to go to bed but I\'m pretty wired.  Wondering if there\'s speed in this stuff... Reminds me of the come-down from ecstasy, but not as sick feeling. If I do this again, it\'ll definitely be half like the previous reviewer said.  Stuff is crazy strong. Most definitely amps desire and erection strength and orgasm strength and ejaculate amount in big way, but this anxiety stuff is for the dogs.  No headaches other that a slightly dull pressure.

Worked as promised

By Mike,  Oct 11, 2014

I tried the 1500mg version on recommendation from clerk at the store, due to my 165lb size. I had been having ED recently from taking antidepressants.  Pill was taken 45 minutes before sex and it worked like a charm. Like other reviews I awoke every morning with very firm erections for 5-6 days, and had them throughout the day.  My only complaint is despite the "no headache" label, I had severe headache later than night and normal headaches the next three. Also disturbed sleep.  Next time I bought a 1750mg and opened it to take half (875mg) each time. Still worked and no headaches.  I would recommend the product.

User Questions and Answers

I took one more knight 1750 last night.... was pretty impressed..... was considering taking another one tonight.... about 24 hours after the first pill. Are there any dangers to this? -Chris

Judging by the response from people who use it, it probably contains the same active ingredient as Viagra. That being the case, I can't really advise you on its safety, since I don't really know what's in it.- Rob

  1. I want to order One More Knight, and or Rhino 7. What do you recommend?

    I want a rock hard but,I don’t want to be screwed over either..Money is Tight!!!!
    1. Hey Percy,

      I wouldn’t recommend either of them. I’m pretty sure Rhino7 has undisclosed ingredients in it, and there are indications that One More Knight does as well. If you’re interested in what prescription medications can do for you, visit your doctor. At least with a prescription, you’ll know what dose you’re getting.
