"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.

Hammer Nutrition E-Caps Race Caps

Hammer Premium Insurance Caps - Regular replenishment of basic nutrients such as vitamins and minerals is crucial for optimizing athletic performance and supporting optimal health, and PREMIUM INSURANCE CAPS is your first step towards achieving both. Athletes and active people deplete nutrients at substantially higher levels than sedentary people do, which makes regular use of PREMIUM INSURANCE CAPS a wise strategy.
Hammer Nutrition Premium Insurance E-Caps

  • Improve energy production capabilities
  • Superior antioxidant support
  • Potential increase in longevity
  • Enhance fat metabolism

Extra Benefits:
Lipoic acid (in the preferred "r" isomer form used in Mito Caps) is often called the "universal antioxidant" because, unlike other antioxidants, it scavenges both water and fat-soluble free radicals.

Workouts under 1.5 hours

  • For all athletes, regardless of size or age, suggested dose is 1 capsule three times daily, with food, on non-workout days. On workout days of 90 minutes or less take 1 capsule 30-90 minutes prior to workouts (with or without food) and 2 capsules after workouts with food. A 4th capsule may be taken with dinner on workout days that were 60-90 minutes in length.

    Workout days over 1.5 hours

  • For all athletes, regardless of age, suggested dose is 2 capsules 30-60 minutes prior to exercise (with or without food), 2 capsules after exercise with food, 2 capsules with dinner. If workout exceeds two hours, 1 additional capsule may be taken every hour during the workout.
  • Hammer Nutrition Mito-R Cell Vitality 90 Caps


    • Better endurance
    • Increase performance time at anaerobic threshold
    • Unsurpassed lactic acid buffering
    • Boost glycogen storage

    Extra Benefits:
    2000 mg of glutamine daily, the amount provided in four servings (one day's loading dose) of Race Day Boost, has been shown to elevate plasma growth hormone levels, a definite benefit while tapering for an event.

    Hammer Nutrition Race Day Boost 48 Servings

    • Scavenge excess ammonia to reduce fatigue.
    • Prolong endurance, even in "ultra" workouts or races.
    • Increase glycogen availability for energy production.
    • Help prevent cramps.
    • Gluten-Free and Vegan Friendly.

    Thoroughly tested over several years in the most extreme athletic endurance events, Anti-Fatigue Caps helps remove fatigue-causing, performance-robbing ammonia. During extended endurance exercise the body accumulates excess ammonia from protein metabolism, which interferes with glycogen production, disrupting energy output.
