GNC products are now GMO (Bioengineered Food Products). Be very careful to read ingredients before purchase! GNC are omitting GMO labels on their advertising pages, be very careful. I've been using GNC supplements for many years now and, unfortunately, GNC products now contain GMO (Bioengineered Food Products), as listed on their new bottles.

Ethan over at the GNC at Frank Lloyd Wright/101 freeway was over and beyond gracious and pleasant. It was 110 outside and I was out of breath and he offered me water. What a kind young man. Wish there were more young people like him.

Ordered online this morning at 7 am. Paid for same-day delivery for an extra charge. Was to be delivered by 10 pm today. Received GNC email that order was on its way at 10 am. Called at 3 pm for update on delivery. GNC rep spoke to Shipt (WHO DON'T SHIP!) that order would be delivered between 7 pm and 8 pm. Received voicemail from Shipt at 7 pm that order was cancelled. It's now 10 pm and order not delivered. Total fraud! I would not have ordered from GNC or paid for same-day delivery if I had known that they would not deliver on their PROMISE!

I ordered supplements on GNC's website and paid for the same day delivery. They contract same day delivery to SHIPT. My package never arrived at my mailroom and they fail to acknowledge their responsibility.

I bought 6 grapeseeds and 5 of them were already expired. Talked to their customer services and sent the pictures of the bottles, but they refused to refund me. This was my very first order and really disappointed.

After I ordered online yesterday, I got an email informing me to pick up at the store. They never informed me there was something they didn't have enough inventory. Otherwise, I wouldn't have been there (wasting time to pick up). After they made this mistake, I showed the man in the store "Your order is ready for pickup!" and told him there was a mistake since the items in the bag didn't match with my order. Then, he just told me in a rude way "go to call the customer service". I said, "this is caused by GNC, not me. It should be your job to contact them to find out what is the issue". Then, he went away and didn't apologize for any inconvenience caused by this.
Then, I decided to cancel the order and contact customer service to cancel the order. The person replied "I have submitted a request to attempt to cancel your order, this is not a guarantee"! It is ridiculous that I ordered it yesterday, and I cancelled the order due to their problems inside GNC, and then they said they couldn't guarantee the order could be cancelled! They wouldn't give you your reward points automatically for stuff you purchased, unless you contact the customer service, and then they will add it for you. Be CAREFUL! Due to the facts, I WOULD NEVER trust their products. Just look at the poor management and poor customer service! Will you trust a business like this? I wish I could give a ZERO star!

Canceled half the order immediately. Sent the free item via overnight so they could continue to charge the overnight shipping. And they have no estimate when or if the only remaining item on my order will be shipped. Definitely not overnight. Customer service was terrible. They might as well have just said you are out of luck and enjoy the inconvenience or trying to get your product or a refund.

3/5/22 a promotion on GNC website cites "buy 2 get 1 free". I bought 2 of the same product but only got 2. When I asked for explanation I was told I had to "buy 3 then 1 would be free". Nowhere on the website is that clear!!! I feel it is misleading and they refused to give me the "1" product (same item) for free as the promotion promises. I am a "pro member", paid $40.00 for free shipping for a year. I choose to never use their products again. I have wasted $40.00.

I set up a monthly order for vitamin supplements. Two out of the three months they have messed up my order. The first time they admitted they didn't have the current product and had shipped a substitute. This last time I have contact customer service twice due to the shipment showing to have been shipped but never delivered to FedEx and never received by me. Each time I complain they give me the same response, "We will escalate the issue and contact you within 72 business hours." No one has contacted me and it has been over two weeks. I tried to get them to transfer me to a supervisor but wouldn't.

In 12/24/21 I purchased an online order. GNC charged split the payment into two. One payment posted other purchase of the total pending which brought my account overdraft and the wrong amount still pending. I called customer service and was treated so disrespectful. I explained that the pending charges needed adjusted due to partial payment has posted. Today 12/29/21 I still have the pending charges of the total amount and then they charged my account twice for the split payment and total payment. Now I have three charges from GNC.
I have sent emails to the Customer service as they requested. They offer me 300 points which is not going to solve the extra charges. I waited for 53 min to speak with a supervisor. I’ve called my bank and was told that pending charge will post tomorrow. So in that case, the two transactions that totaled my balance and the pending charge…. GNC will get both payments which means I was charged twice. Nothing was never resolved here and I will advise not to order anything from online. I’ve been dealing with this for two days and spoke with three representatives. One unhappy customer!
