Boost your endurance and oxygen capacity for a full 5 hours with this unique performance booster.

The science behind Nitric Oxide being a major performance booster is clear. By boosting Nitric Oxide you dilate your arteries and can increase your blood flow to working muscles, resulting in increased endurance and easier recovery.  That's why supplements like Sur Alt Red, BeetElite, and others have become so popular with endurance athletes.

The problem is that most Nitric Oxide supplements use L. Arginine to do this. While this gives you a short spike in Nitric Acid 3 hours after ingestion, the effect fades very quickly.

SwissRX has figured out (through clinical trials) that if you use L. Citrulline, it will signal your body to create L. Arginine (versus supplementing it). This creates the same peak level of Nitric Oxide, but you get to maximum levels after only 2 hours and the level is maintained for a full 5 hours with no decline.

SwissRX has combined L. Citrulline with a patented form of Grape Seed Extract that has been shown to activate your body's production of Nitric Oxide (via eNOS) and help maintain arterial dilation. 

Bottom line: Swiss RX has the most effective Nitric Oxide booster we've found on the market. It will open your blood vessels and increase oxygen flow, allowing you to go faster and harder for longer.

How We Use It

We use 4 capsules 1 to 2 hours before training.

The Swiss RX Story

We set out to find a supplement company we could trust for the world's top endurance athletes. A company that had the same obsession with quality and performance as our athletes do. After all, why spend millions of dollars optimizing the performance of a Tour de France champion only to give him a low-quality supplement with inferior or ineffective ingredients?

Our quest led us to SwissRX. SwissRX takes a "spare-no-expense" approach to procuring the highest quality Pharmaceutical Grade Ingredients. Only 3% of supplement companies go through the rigorous testing required for pharmaceutical grade labeling. But Swiss RX takes it even another step further. Whenever possible, they use the exact same ingredients used in medical studies but are often too expensive for supplement companies to use.  What we love about SwissRX is that our athletes can rest assured they are getting the identical ingredients that were proven to be effective in these studies.

Simply stated, SwissRX products work better because they contain better ingredients.

The SwissRX Guarantee

We know SwissRX is expensive, but you get what you pay for- especially when it comes to supplements. Other brands may be cheaper, but so are the quality of their ingredients. If you're anything like me, you'd rather pay a premium and KNOW you're getting the highest quality and most effective product possible 

That said, you can try it RISK-Free.  We are 100% confident SwissRX is the best supplement in the world, which is why guarantee it. If for any reason at all you are not THRILLED with your results after using this product for three weeks, contact us within 60 days of your purchase and a no-hassle MONEY BACK refund in the form of Feed Credit. There also is no need to return the product to us, just send us a picture.

Everybody loved the high-tech style and amazing functionality
Color: Black/Yellow
I'm not a Timex fanboy, and I've had my fair share of problems with the Expedition line, so this review is my honest opinion as a man who's worn Armitrons and Timexes since I was 10. I remember in 1992 when the Timex Ironman Triathlon with Indiglo was first launched - My older brother got one, then me and my neighbor friends. Everybody loved the high-tech style and amazing functionality. Even Bill Clinton was rock'n this watch, for those who don't remember. Quite simply, this is the perfect watch at a great price, in my opinion. Perfect as a gift for any man, and I think the original black/olive drab/yellow coloration is still the coolest. In this day and age of smartphones, it still pays to have this watch. The alarm is less annoying sounding than a cellphone, and doesn't wake up the entire house. To turn it off, just tap the watch, no more reaching for the phone or alarm clock. Timer comes in handy for anything; timing my kids' timeouts when they get in trouble, 15 minutes room clean-up times, etc. Chrono is fun for anything you wanna use a stop-watch for. I set the second time zone for Vietnam time. It really is a million times easier to use this watch for all of its functions than reaching for a smartphone or alarm clock, etc. If you;ve been relying on your phone for a few years as a watch/chronograph/timer/alarm - you'll be so glad you finally got a watch like this. I've never tried a smart-watch, however I feel those are not as necessary,durable or practical as a real watch. Other Timex watches I've used were freakin' trash - couldn't throw em away fast enough. Might as well open the box while holding it over a trash can, so the watch can fall right in when you open the box. That's my experience with the Expedition line-up. Back to this watch: The only thing I wish this watch could do is measure activity thermogenesis (calories expended throught the day) or work as a pedometer, which some smart-watches and other devices can do. I also cannott decide if I like this new, slightly larger, heavier/thicker design of the Ironman Triathlon over the 1990s design. The 90s models styling was "tight to death'. Star-split buttons were seperated. The mode button was yellow. Overall more compact and bi-cultural;by that I mean it looked great as an athletic watch or a politician, business man wathc. This new model is bigger, better ingress/shock resistance, and more of an athletic style over all, and is a little less colorful. I almost went with the G-shocks, but they still just look like crap and are waay to expensive. Sure, they have some better features, can survive WWIII, but I am a traveler. I need a watch that can work in the dark in any environment. The G-shocks are often using some kind of solar battery crap and rely on cathing a signal from an American automic clock in Colorado - good luck with that while your in Thailand on vacation.

Great Product. Easy to use.
Color: Black
This is the third running watch I've had and it's my first Timex. I've owned to Casio's before (one being a g-shock), but after finding my g-shock to bulky and cluttered, and loosing my other Casio I picked up from Walmart, I decided to look around to find a new durable running watch. I run cross country and track so going from a generic stopwatch to a 30-lap chrono watch has been sweet. The lap timer is easy to use and the display is big enough to take a glance and see my split and total time side by side. The recall feature works perfectly and you even have some room to adjust the settings to configure your lap display how you like it. My favorite thing about this Timex, is its ease of use. The only time I've had to look at a manual is when I first got the watch. The display updates as you go through the various modes to show you what the new buttons mean so there is never a question on how to set the time or recall your laps. This watch is extremely durable. It has already taken a few shots and I've swam with it on several times. The screen and body have held up nicely and I don't foresee any problems with them in the future. The strap is great also. I really like the notch that keeps the excess strap in place. The countdown timer and the alarm both work as expected. The timer has some different settings and is easy to set up. My only disappointment with the timer was that you can't set different intervals. Like if you want to run for five minutes and walk for two your going to have to invest a little more for a watch that allows different intervals. The alarm works well too, and the beeping successfully wakes me up in the morning, but I'm not a heavy sleeper so some may find it too quiet. Overall this watch is durable, easy to use, and can track splits really well. The watch is a little bulky if you are used to a more minimalist watch but for me the weight was perfect, and for the price you can't go wrong with this watch.

Trusted Brand Delivers Again
Color: Black/Yellow
I had my previous Timex watch for 30+ years and it finally died after getting wet, so I replaced it with the closest model I could find to it. PROS: - Has the basic functions I needed: Clock, 2nd Time Zone Clock, IndiGlo backlighting, Alarm, Timer, Stopwatch. Allows me to leave phone at home and just take this out. - Easy to set time/date/etc. Can turn alarm on / off easily. Buttons for timer/mode switching work fine. - Clear display so easy to read. The backlighting makes this even better. - Can swap out the band (I put mine on a Chums' "The Band" that I like) if the new one takes 19mm pins. CONS: - The only thing I dislike is it is heavier than my old Timex. A little bulkier too. Not annoyingly so but noticeable enough for me to comment on it here.
