Nathan was so helpful, courteous, very knowledgeable and patient as I am completely a newbie. I had tried some other protein powders and never liked them because of the flavors & texture (You CANNOT just stir protein powders!), never knew I needed to blend them or use that cup container with the whisk inside, no one EVER mentioned that before 🤦, except for today, Nathan did❣️ I've wasted time and money on protein powders to know that was necessary to fully enjoy them. He gave me great suggestions and flavors and other ideas on products and how best to use them.

DO NOT GO TO THIS OAKLAND LOCATION. The garbage employee stayed on his phone the whole time. When cashing out a $300+ order he acted like I was holding him up from talking on the phone. He was disrespectful all around. I have Pro Access. He lied and said I had zero reward dollars available to use. He lied and said there was no promo but one get one 50% off going on. Worst service at any GNC store I’ve ever been to. Avoid this store at all costs unless you want to waste your money.

Didn’t find what I was looking for but the employee immediately knew off the top of his head that they didn’t carry the exact items I was asking about and walked me through the similar options in a very succinct yet detailed and helpful way.
