One of the best nutritions brands in the business
As someone who’s trying to put on a bit of size, previously I struggled to get the calories and protein in and the best way to supplement with protein shakes and protein bars. The pre-made protein shakes, really do make a difference to get in the additional protein and I would recommend them. The brand itself is great quality the and I’ve never had issues with delivery or service.

I was generally satisfied with the products, been taking them for a while. Last creatine tub arrived with the seal slightly opened, so I tried to get a refund / replacement. The process has taken 3 weeks so far and still haven't got a resolution

Shit show
Dpd said that they failed once too me and multiple times too the customer service rep from optimal nutrition I got in contact with saying they failed to deliver my order however I can see on my ring doorbell no truck came into my street anywhere close too the time they said it would be delivered so after much effort to get in contact with their customer service they said that I’ll be refunded as the Dpd have force returned it without even asking and it’s been well over a week now still no more word on what’s happening and no money that’s been sent to me wish I could give less than one star

Ordered about 12.05 on Friday lunchtime, and it arrived about the same time on Saturday, kept up to date with where the order was. Can’t fault it, plus I got an email suggesting some nice recipes to use it in

Overall very satisfied.
The process from ordering to delivery was clear and straightforward. Messaging and updates were unambiguous and frequent and delivery was fast. When my clear protein arrived it tasted good and wasn’t too sweet like some varieties - hopefully the results will speak for themselves.
