I got my shipment of Glukos energy powder yesterday, days after ordering it. Specifically the tropical fruit flavor. I have not yet used it while cycling because my left knee has become sore, and I'm resting it. When I resume cycling I'll report back.
I did dissolve one packet of the powder in a glass of water, and it tastes pretty good. I had a sense of fullness in my belly. A little bit of the product did not dissolve completely in that quantity of water, there were several grains of the product visible on the glass bottom. I assume that means I should have dissolved it in more water than I had used.
I'm not sure if the Glukos is any better or different from energy powders I can get in my local REI store or through Amazon.
Glukos the company has not responded in any way to the email that I sent to their customer service email address. I sent it on Sunday and so far there has not been a word from them, and I did check my email spam folder.
Amazon and REI both have great product selection and customer service. Glukos offers very long shipping times to get their product, and no customer service other than order confirmation and shipping notification emails. I will probably not order from them again.
It was an interesting experiment though.
