I've recently ordered a sample pack of Neurostim to try. Absolutely loved it. Just two capsules in the morning did the trick for me. Had an increased focus and cognitive energy for entire day. However I'm a bit confused by the contents. The bag sample capsules arrived in listed all the ingredients from the website and also 10mg of Vinpocetine per serving. I've taken Vinpocetine before and it worked really well for me. So now I'm wondering if I order a bottle of Neurostim, would it contain Vinpocetine as well as sample bag? It is not mentioned on the product page for some reasons.
