My HG supplement!!

Posted by Reviewer3327650 on Jan 08, 2009

As soon as I found out the effects that EPO has on a woman's body, I ordered this brand. I took 1 gel three times per day for 2 months to see how it would affect me. The first month I noticed that my menstrual cycle cramps (which used to be excruciating!!) lasted only one day as opposed to 5-7 days and were not as sharp as usually. I also noticed that my skin was much better and did not break out during that period. And another great effect for me was lack of hangovers during the time I took this supplement. I am a very light drinker and I get hangovers form just 2 drinks. Basically, the quality and the value of this brand of EPO makes it my holy grail supplement! I will definitely reorder this item again and again! Thanks iHerb!

no complaints

Works as well as Now Foods brand. I have no complaints. I started with Now because of the higher dosage. I ordered these before I ran out because they are cheaper and I figured they would be sufficient to maintain my needs. So far, I have not gone back to any night sweats or severe cramping. I will continue to buy these.
