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

Nancy H.

Dear,

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.

Regards,

Brian H

 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.

First Endurance EFS Liquid Shot Q&A

Q: What is EFS Liquid Shot?
A: EFS LS (liquid shot) is a new energy product that provides endurance athletes with the nutrients they need to fuel working muscles and increase endurance during exercise. The EFS formula utilizes the latest clinical research on endurance nutrition and input from some of the best endurance athletes in the world.

Q: How is the EFS-LS different than most gels on the market?
A: Unlike the "gels" that are on the market, the EFS Liquid Shot does not contain any gelling agents, which slow down absorption and digestion. The EFS-LS also uses highly versatile and Eco-Friendly packaging that can be recycled and minimizes waste. EFS-LS delivers 400 super-charged calories that are fortified with over 1,500mg of electrolytes, 1,000mg amino acids and 100 grams of simple & complex carbohydrates- all in clinically effective doses.

Q: I've heard that there are benefits to having protein during exercise. Why doesn't EFS-LS contain protein?
A: EFS-LS contains 1g Free Form Amino Acids per serving which is the equivalent in BCAA and Glutamine profile to 5g Whey Protein. Protein naturally contains Branched Chain Amino Acids and Glutamine. Clinical evidence that shows the benefits of Branched Chain Amino acids and Glutamine during exercise dates back to 1991. These clinical studies show supplementing with as little as 1g Free Form Amino Acids improves performance, reduces post-exercise muscle damage, improves muscle glycogen resynthesis, reduces central fatigue and improves rate of perceived exertion.

The First Endurance Research Board sides with the abundance of clinical studies supporting improved endurance performance while supplementing with Amino Acids during exercise. In addition to the clinical research, other factors lead to a decision to use these Free Form Amino Acids over complete proteins.

-Proteins are more difficult to digest than Amino Acids during exercise

-Proteins take longer to get absorbed than Amino Acids

-Proteins don't taste very good during exercise

-Proteins can reduce the glycemic index of a drink, further reducing its ability to be quickly absorbed

-There is considerably more research that supports the benefits of Free Form Amino acids than complete proteins

Q: What are the benefits of using EFS-Liquid Shot during exercise?
A: The benefits of EFS Liquid Shot are:

-Supplying fast and sustained energy for muscles

-Improved fluid absorption

-Reduced cramping and dehydration

-Improved performance

-Easy to digest and absorb

-Improved glycogen resynthesis

-Delayed central (mental) fatigue

-Replenish electrolyte loss.

Q: How long after I open an EFS-LS do I have before I need to consume it?
A: The timeline begins once you take your first swig of the EFS liquid shot. Following your first swig, EFS LS should be consumed within 24 hours and should be stored in the refrigerator.

Q: Can I re-use the flask?
A: Yes, the EFS Liquid Shot flask is re-sealable, and refillable. Re-using the flask is eco-friendly because it minimizes waste. The EFS-LS flask can be cleaned in the dish washer. First Endurance offers a large 32oz Jug that can be used to re-fill flasks. The EFS Liquid Shot flask is also recyclable.

Q: How long does the large 32oz Jug last and how do I store it?
A: The large jug will refill six (6) flasks. It comes with a one year shelf-life and should be stored in your refrigerator once it's been opened. Once the flask is filled it should be consumed within 24 hours unless stored in the refrigerator.

Q: How does it taste?
A: EFS-LS is a light, great-tasting product that's sweetened and flavored with 100% natural ingredients. Because EFS does not use gelling agents, the consistency is much more fluid making it easier to absorb and improves palate.

Q: What flavor is the EFS Liquid Shot
A: Currently, the only flavor available is Vanilla. First Endurance plans to introduce additional flavors of the EFS Liquid Shot later in 2008.

Q: How much EFS-LS should I use during my training and racing?
A: Clinical research shows that athletes should consume about 200 calories, >1000mg Amino Acids, 400-600mg sodium and equivalent balance in all electrolytes should be taken every hour during exercise. EFS-LS is designed to maximize all these levels. At this rate a flask is sufficient for a two hour exercise bout. Because athletes vary greatly in their caloric demands it is best to try different levels to see which level works best for you.

Q: Am I suppose to use the EFS liquid shot, EFS drinks or the bars, how do they differ?
A: First Endurance offers EFS drinks, EFS bars and EFS Liquid Shots. Depending on your exercise time and personal nutritional requirements, you can use one, two or all three of the EFS products together, as a system, to maximize endurance and performance during exercise.

Q: What types of athletes should be taking EFS-LS?
A: The following symptoms will all benefit from use of EFS 1) Athletes who experience cramping from strenuous exercise. 2) All athletes who demand rapid fluid absorption in order to stay hydrated. 3) Athletes who want all the benefits of protein without the heavy/chalky consistency of protein drinks. Essentially any athlete exercising for one hour or more will benefit from the use of EFS in their training and racing.

Q: Should I use EFS-LS even when it's cold, like during XC ski races?
A: Cold weather sports still put a considerable fluid and electrolyte demand on the athlete. EFS works just as well in the cold as is the heat. The high sodium content in EFS may even help reduce the drinks propensity to freeze. (this has not been tested).

Q: Should I use EFS in short races?
A: Short races generally don't put a heavy demand on your glycogen, carbohydrate stores, given that you are well nourished prior to the start of the race. During a short race athletes can be slowed significantly from cramping and electrolyte imbalance. A serving of EFS can be used 15-30 minutes prior to a short race to assure adequate carbohydrates and electrolytes are available for the intense effort. Short race is defined as one lasting less than one hour.

Q: Should I use EFS in long races?
A: During long races (3 hours+) considerable stress is put on an athlete's body. 1) Glycogen (energy) stores are depleted 2) cells experience damage from cellular oxidation 3) electrolytes are depleted and 4) amino acids are depleted. 1) EFS replenishes glycogen by using a mix of high glycemic carbohydrates including both simple and complex sugars. This easy to digest mix is rapidly absorbed and delivers fast and long term energy. 2) EFS provides the most potent electrolyte profile available. The combination of all five electrolytes deliver a potent 1500mg per serving, helping to prevent cramping. The 400mgs sodium per serving also aids in maximum fluid absorption so you stay hydrated throughout your training and racing. Supplementing with additional salt tabs, electrolyte tabs, or salty snacks is no longer needed when using EFS. 5) 1000mg of Amino Acids offers the same BCAA and Glutamine levels as 5g Whey Protein. These amino acids have clinically shown to improve performance, reduced post-exercise muscle damage, improve muscle glycogen resynthesis, reduced central fatigue and improved rate of perceived exertion.

Q: What's the carbohydrate source in EFS-LS?
A: EFS replenishes glycogen by using a mix of high-glycemic carbohydrates including both simple and complex sugars. This easy-to-digest mix is rapidly absorbed and delivers fast and long term energy. Clinical research shows that mixing carbohydrates sources is far superior to any single source of carbohydrates.
The carbohydrate blend is maltodextrin, glucose, sucrose.

Q: I am prone to cramping during longer training and racing. Will EFS Liquid Shot help me with cramping problems?
A: Nutritionally cramping stem from electrolyte imbalance, electrolyte depletion and/or dehydration. EFS LS provides the most potent electrolyte profile available. The combination of all five electrolytes deliver a potent 1500mg per serving, helping to prevent cramping. The 400mgs sodium per serving also aids in maximum fluid absorption so you stay hydrated throughout your training and racing. Supplementing with additional salt tabs, electrolyte tabs, or salty snacks is no longer needed when using EFS-LS.

Q: How many servings are in a container of EFS?
A: The 5oz flask contains one serving. The 32oz Bulk Jug is enough to fill six flasks.
