Why MyCore, and Why the Code Beats Waiting for a Sale
This is the shop I actually buy from, and have since I started training properly — the partnership came years afterwards.
Why they beat ordering from a UK site: they are 100% Irish, Bishopstown in Cork, Irish registered company 599724. Orders leave Cork and arrive next working day, and a problem is handled by a Cork shop instead of a returns portal in another country. The range is wider than MyProtein's own catalogue — every protein format, creatine in five forms, pre-workout, aminos, vitamins, and gym equipment down to barbells and benches — stocking Optimum Nutrition, Dymatize, Ghost, Trained By JP, Alpha Lion, Redcon1 and MyProtein themselves.
NNF10 has no expiry date and does not wait for a sale. The 10% is there whenever you order on full-price stock, which is the difference between this and the big UK sites, where the good price only exists during a promotion window.
They also bring in things nowhere else here stocks. Professor Nutz low calorie peanut butter is the one I reorder without thinking — 17.5g of protein per 100 kcal against about 4.4g for ordinary peanut butter, imported from the US, and reviewed in full including the six-person study the brand leans on.
What It Actually Costs
Prices read off their own site on . They are theirs and they move, so treat this as a guide rather than a quote.
- Optimum Nutrition Gold Standard Whey 900g — €38.99, so €35.09 with NNF10
- Optimum Nutrition Gold Standard Whey 2kg — €74.99, so €67.49 with NNF10
- Per4m Whey 2kg — €55.99, so €50.39 with NNF10. Their own-label sits well under ON for the same job
- Creatine monohydrate — from €14.99 (EHP Labs Crea-8, and NXT 300g reduced from €19.99), up to €37.99 for OstroVit 1kg
- Professor Nutz low calorie peanut butter — €17.99, reduced from €19.99
The bit most code pages will not tell you: two of those are reduced today, and NNF10 does not stack on anything already cut. On the NXT creatine and the Nutz jars you take the sale price and the code does nothing — which is the right outcome, it is just not the one a coupon site wants you to hear.
On creatine specifically: it is the same molecule at €14.99 as it is at €37.99. Buy the cheapest monohydrate in stock and put the difference into food.
Is MyCore Worth It?
For it: the range is genuinely wide, the own-label is cheaper than the big names for the same protein, orders leave Cork and land next working day, and a problem is handled by a Cork company rather than a returns portal in another country. Free delivery starts at €75. If you are buying supplements anyway, the 10% is there on full-price stock every day of the year instead of only during a promotion window.
Against it: individual lines are not always the cheapest in Europe, and if you are happy waiting for a UK flash sale and dealing with cross-border returns, you will occasionally beat these prices. Stock moves too — a few of the products above were out of stock the day I checked.
Who I would not bother sending here: anyone buying their first tub. If your calories and protein are not sorted, no supplement fixes that, and this shop will still be here in three months.

Why This Page Exists
Worth saying plainly: I have been buying from MyCore myself for about three years. The partnership came after that, not before it, and I still take no commission on anything you buy here.
Most discount code pages are scraped coupon-site rubbish full of codes that expired two years ago. This one is a straight partner arrangement: MyCore Supplements gave a code for people who come from here, and it is written down plainly with the exclusion stated up front rather than buried.
No commission, ever. There is no referral tracking on that link and nothing comes back to me if you buy. Everything on this site is free and stays free, so there is no reason for me to push you at anything. If the sale price beats the code, take the sale price.
Supplements are the last 5% anyway. If the food is not sorted, no tub fixes it. Start with fat loss basics, work out your numbers with the macro calculator, and see how much protein you actually need before spending anything.
Frequently Asked Questions
What is the MyCore Supplements discount code?
NNF10. It takes 10% off your order at mycoresupplements.ie. Enter it in the discount code field at checkout.
How do I use the NNF10 code on mycoresupplements.ie?
Add what you want to your cart, go to checkout, and enter NNF10 in the discount code box. The 10% comes off before you pay.
Does the code work on sale items?
No. NNF10 excludes anything already reduced or on special offer. On full-price items it works normally.
Where does MyCore ship from?
Cork. Orders ship from their Cork warehouse with next working day delivery within Ireland, and delivery is free on orders over €75.
Do you earn commission if I use this code?
No. There is no referral tracking and no commission on anything you buy. The code is a discount for you, not a payment to me.
Is there a MyCore Supplements promo code or voucher code as well?
Same thing under three names. Promo code, voucher code, coupon code — they all mean the box at checkout, and NNF10 is the one we have. Codes you find on aggregator sites are scraped rather than given, which is why so many of them fail at the last step.
Does NNF10 expire?
No end date has been set on it. It is a partner arrangement rather than a seasonal campaign, so it runs until MyCore Supplements or this site ends it. If it ever stops working, tell us and the page comes down — we would rather have no page than a dead code.
Do I still get free delivery if I use the code?
MyCore delivers free within Ireland on orders over €75. NNF10 comes off first, so an order sitting just above €75 can fall back under it once the 10% is applied.
Discount codes and delivery terms are set by MyCore Supplements and can change without notice. Details here reflect what their site said when this page was written.
