ProEndorphin, Citrus Flavor, 20 effervescent sachets

Awesome product. Gives you a constant supply of energy and focus through out the day, with the added benefit of taking the edge off of your appetite. No jitters, no crash, just steady energy. A superior product compared to Red Bull or Five Hour Energy. It was actually recommended by my Dr. for helping control my fatigue from Rheumatoid Arthritis.

What turned out to be a mistaken purchase, became a good buy!At first I was looking for a HGH(Humane Growth Hormone) supplement, andPro Endorphine is the brand my chiropractor recommended... butwhen I followed up on my chiropractor, he said this wasn't thesupplement and he was mistaken. But I bought it anyway, and boydoes this work! Don't get too hyped up, this is not the equivalent of steroids so forthose who rated this poorly, you better straighten your facts up!But it does help you get out of the funk and bring it when it comesto hard workouts(I'm a competitive swimmer), I really felt the renewedenergy, and this gave me the endurance I've never expected. If you wantnumerical statistic of my improvement, give or take 15%-20% improved performance.I know not bad right! So ditch your impotent Gatorade's and buy this NOW!

I have been using Proendorphin for years. I use it maybe once a week when I am dragging and it really works without giving you the jitters. I also helps mentally a little. We recently found out that my wife, who is very sensitive to caffeine and cannot even drink it in small quantities, can use this product. She only takes 1/2 a packet because she is very sensitive to this also, but it actually works for her. This, of course, keeps me happier because my wife is now less grumpy :)

I used many pre workouts, the Cellucor C4 Extreme, arnold 3D, 3D jack, Pack Animal .. but Proendorphin really surprised me ... the product does not cause arrhythmia provides a gain of energy without exaggeration and side effects ..porem the effect not is very durable .. the the only thing against the product's price and quantity provided only 20 sachets for U $ 32.00 .. really the product could be better in this regard.

Want a real picker upper? This is the one. Whether you're going to the gym, or just woke up feeling sluggish, it really works. It also has good vitamins in it! I've also taken this sachet in the afternoon, when I'm too tired and have an evening engagement. It's great. I never want to run out of this. My boyfriend keeps me supplied with it.

Was given ProEndorphin by my Naturopathic doctor who said it would be a good energy boost. Experienced a 'niacin rush flush' the first time I took it. Don't be alarmed--it's a good thing. This stuff is great for good and steady energy. No spikes and drops. Really love it before exercising or just at those periods during the day when you drag.

This product did nothing it claimed to do. I am 65 yrs old and I expected to feel some increase in my energy level or that so-called RUSH I might get. But like so many other products that claim the same, this was a big dissapointment as well. I'm on Social Security and shouldn't have believed the hipe....shame on me for buying into it and dipping into my limited income.Sheila - Springfield, MO

I originally gave this product a 5 star rating but must now downgrade it.....i came across this product while reading one of russel simmons books. i purchased it to give me more stamina during my cardio work outs. and in all honesty it is effective in that it allows me to dig dwn deep in push myself to get through my work out. shortly after purchasing this product i started to notice frequent heart burn.....i really just attributed it to eating spicy foods.....overtime it become more frequent and regular.....i mentioned it to my doc who gave me an rx for omeprazole....however, it did not appear to help.......then came the insomnia(i was stricken with a sever case of menengitis which affected my brain so i attributed the insomnia to this).......for this my doc gave me an rx for ambien CR. but there were nites that no matter how many ambien cr i took and unisom and rapid sleep.....i could not fall asleep.......(its fair to mention that i only take proendorphin when i do cardio which was twice aweek. i spoke with my doc about the sever insomnia and after some testing he finally attributed the insomnia to stomach acid(this appears to be caused by the proendorphin).....for the stomach acid my doc advised takin a probiotic supplement high in culturesthe probiotic does the trick because once i take it the ambien kicks in.....my doc advised me to discontinue taking proendorphin because he also attributed this to weakining my esophagus......
