Goos product and good service

DPD have not delivered, you have not replied to emails, no working phone number. Have reached via FB and insta and no luck getting hold of anyone. Looks like I will have to resolve via my bank. Company has been useless

I ordered the 4.5 kg resealable bag of protein from Optimum Nutrition, but the bag I received does not reseal at all. I even tried removing the protein stuck around the zipper to see if that was the issue, but the zipper simply won’t close.

For a product that costs over £120, this is extremely disappointing. The resealable feature is important for maintaining freshness and convenience, especially for such a large bag.

What makes the experience worse is that I contacted their support team via email and it has been over 48 hours with no response. I expected much better customer service from such a well-known brand.

Overall, very disappointed with both the product quality and the lack of customer support.

I love these protein powder!! I’ve bought the vanilla Gold standard Isolate and the Whey cookies and cream and the flavour is absolutely delicious 🤤 it mixes smooth as well. And oh delivery was fast.

Order said delivered to collection point but wasn’t. Dpd says contact seller. Well thats not so easy! Optimum nutrition have a phone line but after sitting and working my way through the annoying machine, you can’t actually talk to anyone and directed to email. Unacceptable customer service

Excellent protein - great taste (especially the double chocolate), mixes easily with my oats and equally good as a shake.

I did a price comparison and decided to order straight from ON website as it was the most cost effective.

I buy this protein with confidence and would highly recommend it.

Great flavor and excellent supplement

When I started training finding the right protein was an issue , tried few other protein powders that was hard to mix and Heavy to drink . But when I tried Gold standard whey protein found best whey protein in UK market, very easy to mix and much easier to drink.
Very good customer service friendly helpful and pleasant staff, I never had any complaint about the product quality and service and on time delivery.

Customer service was really good. Unfortunately the creatine I got was gritty and the flavour was really not nice (orange). A really expensive mistake to make

Super fast delivery, next day now! Products are great, lots of choices and flavours to choose from. From a leading nutrition and performance brand, I wouldn’t expect anything else, that’s why I don’t go anywhere else. Been using their products for years and have always got great results with superior recovery. Would definitely recommend if your health, wellbeing, body and recovery are your goals.

I’ve been using this product for years but first time I’ve ordered direct from the manufacturer.
I am so impressed. The price was great. Next day delivery was fantastic with an hour allotted delivery slot, super impressive.

Best bang for buck protein and creatine on the market. Always tastes and mixes well.

Platinum range is fantastic.

I use products from this company for a while now and it has never failed the expectations. High quality products delivering a great result if combined with consistent and disciplined training.
Definitely would recommend to anyone who values quality and wants to achieve great results !!!

I bought the 4.5kg of whey protein so I can have it for a long time, and although the protein itself is of great quality (absolutely the best), the packaging just doesn't seal properly.
I tried it in all possible ways, but it's just faulty and will not stick no matter what. It's a pity, because now I have to use other ways to close it and it's definitely not air-tight. You should review your production line because something is not working well.
