Hi David,
Thank you for your feedback.
If the shake tasted too thin or watery, we would suggest trying it with less liquid than recommended, as this can help create a thicker and richer texture. You can also experiment with adjusting the amount of water or milk to suit your personal preference.
If you would like further advice on preparation or believe there may be an issue with the product, please don't hesitate to reach out to our Customer Support team, and we'll be happy to assist.

A Priced out loyal customer
Been a customer for over 20 years - brilliant product BUT... SO far out pricewise now. Why can I obtain this in Holland for £73 per 2kg pack and in the UK it is an incredible and unsatisfactory £98!? Such a sad former customer....

Hi Daniel,
Thank you for sharing your feedback.
The damage shown in the photo you previously provided is extremely unusual, and because this concerns a consumable product, it should be examined by our Quality Team. To allow us to investigate properly and resolve the issue, we previously offered to arrange a return label so that the product could be returned, inspected, and refunded.
At this time, we have not yet received confirmation from you that you would like to proceed with the return process. If you wish to move forward, please contact our Customer Support Team and we will be happy to provide the return label and assist further.
We remain committed to resolving the matter as quickly as possible once we receive confirmation that you would like to proceed with the return.

Doesn’t get any better quality or service, heavy on the emails though, had to unsubscribe within a couple days I had a bunch of emails, a reminder would’ve done say 30 or 60 days after receiving my nutrient's. Otherwise buy with confidence been using optimum nutrition for a while, if I wanna cut in or bulk or maintain they do the job perfectly

I’m giving one star
I’m giving one star, which I genuinely feel bad about, as the service was good up until the purchase. However, I’ve had to chase several times for a return label, and the customer service since then has been really disappointing. I expected much better support when trying to arrange a return.
Hopefully, I won’t have to chase them again for my refund.

We appreciate your patience throughout the process.

Seals tampered with on both products in order.
Order received in sealed brown box but both products within box were opened or tampered with. One seal was lifted up and the other seal was pushed through. Consumables are now worthless.
Customer service telephone number refers to email customersupport. Email no longer is used. Needed to submit query on website. After submitting complaint was told ticket has been issued, but there was no ticket reference number. I have received no email to confirm complaint received. Very unhappy and trust impacted.

Poor service
Poor service.
Order delivered with a hole in the bag. Order was sent back and have not heard anything, not a single update since 04.08.26.
I have reached out in 3 separate occasions via email (calls are not being accepted). No response has been given.
It has been 3 weeks and I’m now £170 down with no protein and no refund.
