Recently I tried PQQ (10mg) + ubiquinol (50mg). It was too much, I had heart palpitations. I tested PQQ only. After 1 week, today, I do not take phenylalanine/Korean ginseng anymore. I have a better, smooth, not too high, level of energy. I re-ordered 4 bottles of PQQ, I want to give it to my mother (she has weak thyroid and surrenals as well) Pay attention, the first 3 days, I had the weird feeling that my legs and my arms were flooded by electricity. And coffee made it worst. Please note that when I started PQQ, I was taken other supplements: ashwaghanda, rhodiola, American ginseng, Korean ginseng, maca + vit C + acetyl-l-carnitine + iron + phenylalanine + glutamine + pregnenolone (I have hormonal imbalances) Excuse-me for the possible mistakes, english is not my mother language.

After taking this supplement for one week, I can tell the difference in my workouts. I have more energy, I feel stronger and less fatigued after workout. I will keep taking as long as I can afford buying it. Thanks Iherb for the hands down fastest shipper on the net :-).

What I like about Life Extension products is that they are all backed up by good, independent research, which leads them to so formulate these products in the first place. This is no less true for this product whose ingredients have been shown to restore new mitochondria to cells, which helps retard the aging process.
