"I think you guys [gals ?] are the best. Free shipping on hammer products and super fast service. What's not to like?"

Proline Sports Nutrition & Equipment,

I was shopping for the product below using Google as which time I saw your Google add. This was the first I heard of your company. I went to your site and liked what I saw and proceeded to order the Optygen HP. The order was placed on late Friday afternoon and was delivered (to my surprise) on Saturday. Your service is awesome as well as your price match guarantee. There is no doubt that I will continue to use you in the future, as well as recommend you to others.

 I am very impressed with your customer service.  I was worried about getting my order with a marathon a week and a half out.  Wow, less than 24 hours and my order was sitting on the porch.  That is phenominal service.  I will definately shop with you again.  I have had free shipping take 10 days.  Proline Sports Nutrition is a site I will recommend to my many running/cycling buddies.  Thanks for the great response.  BTW, that info on the Hammer Nutrition products was wonderful!!  It helped me hone in on my nutrition/hydration plan for my marathon.  I printed off the entire 120 pages!  This is my 4th marathon.  I've trained hard, and my Hammer plan I do believe will give me a PR.

FRS chews take you up a level and keep you there. FRS contain quercetin - a natural, powerful antioxidant found in blueberries, red onions, apples and cocoa. Quercetin helps extend your body's natural adrenaline as well as neutralizes the oxidants in your body that cause fatigue*. Joining quercetin to keep your energy on the level are key vitamins and potent antioxidants from green tea leaves. Inside each serving is a daily allowance of enhanced mental focus, increases performance and the energy to keep you going. So rise up, stay up and enjoy your day!



FRS was invented by a team including Dr. Mitsunori Ono, PhD as a fatigue fighting and general health drink. It was then tested and refined by Dr. Ono and Dr. Lan Bo Chen, PhD, who at the time were both researchers at Harvard University. It was later discovered by endurance athletes who found that it boosted and sustained their peak athletic performance while supporting their overall health. Now FRS is used by anyone who wants a healthy and sustained boost of energy.

The key ingredient in FRS is Quercetin.
(pronounced: KWAIR-suh-ten)

Quercetin is a powerful natural antioxidant found in the skins of apples, blueberries, and onions. It unlocks and helps extend your body's own natural energy, by protecting the adrenaline your body naturally creates to give you energy for small daily tasks like staying alert and focused at work as well as helping you get more from your workouts. Experts believe quercetin works by allowing the energy that your body produces to stay active in your system longer, without forcing your body to produce more adrenaline so that you feel more energy for a longer amount of time.

All Quercetin isn't the same though. FRS uses only QU995(TM), the highest purity Quercetin available, and combines it with a patented mix of vitamins, metabolic enhancers, and antioxidants to support absorption.


Make FRS part of your day by taking one serving in the morning and one in the early afternoon. Take another serving whenever you need extra energy or 30-40 minutes before exercise as a pre-workout boost. When consumed on a daily basis, FRS helps fight fatigue and provides powerful antioxidant protection to support your overall health.

FRS Boosts Sports Performance Study # 1 - MacRae H. and Mefferd K. 2006 An independent, double-blind, placebo-controlled crossover study on the effect of FRS on cycling performance in eleven elite cyclists was completed at Pepperdine University in June 2004 and is published in the International Journal of Sports Nutrition and Exercise Metabolism. The results were dramatic - one minute and 31 seconds improvement in a 30 km simulated mountainous time trial.

FRS Enhances Work Performance
Study # 2 - Derek E. and Bell M. May 2005 During a six-week study, university employees were asked to perform and report on their daily jobs, which required physical exertion, lifting, repetitive movements and attention to detail. At the end of the study, scientists measured the work performance and found that when the workers took FRS they experienced:
