I have been using PQQ for energy/mitochondria for at least 2 decades and have tried many brands. A lot of them just didn't work well. I stuck with a good brand for years despite its being pricey because it worked. I use PQQ along with NAC and CoQ10 or energy, mood, and overall well-being. It's a combo I would never want to be without. Recently I have found DOUBLE WOOD PQQ. It works! In fact, it works great! It works as well as the more pricey brand at a much more affordable price. I will stick with them as long as they stay in business. I will be 80 this year and everyone asks for my energy/attitude secret, even people 1/2 my age. Now when I share my secret, I recommend Double Wood brand! Read more

Double Wood, me parece ser una marca confiable, en general un producto a precio accesible, rango de mg por capsula en el recomendado y como plus las capsulas adecuadas para consumo vegano son pequeñas, estoy en un protocolo de tomar PQQ 20 mg con 100 mg de Ubiquinol buscando obtener una mejora en la biogenesis mitocondrial, llevo medio frasco y hasta ahora todo va bien.

I bought this product to help improve mitochondrial function and potentiate the CoQ10 supplement I was already taking. Double Wood PQQ has helped to improve my energy levels both physically and mentally. I'm still lifting heavy kettlebells at the age of 50 and this product helps me to sustain both my physical strength and mental drive to get through grueling training sessions with plenty of energy left over to do all of what needs to be done in life. I also recommend using their DHEA, which I started using a month or so after the PQQ. The two products in combination have a great synergy for me, where I have been able to train harder, gain strength and increase my muscularity noticeably in a matter of a few weeks. Overall, I find Double Wood's products to be of high quality and good value for the money. Read more
