I've experienced that numbness too! I was wondering if that happened to anyone else. I'm not a huge fan of the taste either. But I am a huge fan of the effects. I do put alot of effort into getting all product out of the ampule, and would advise you do the same on your next attempt and see if it goes any better (alot of people actually chew on them to get it all out).
If that is the case , we are pretty screwed brother . I don't think there is going to be a pharma deal that will bring in lots of revenue anytime soon. I was hoping they would be able to sell the sh&@ out of the products we have now to bring the stock price up. I have not tried powerfuse but like electrofuse and enerjel
