Why HardCore, and Why the Code Beats Waiting for a Sale
Another shop I buy from myself. Every brand listed on this site is one I use — that is how the partnerships started, and nobody paid to be here.
What you get over a UK order: stock ships from an Irish warehouse, so delivery is short and a return does not cross the water.
NNF10 has no expiry date. It is a standing arrangement, not a seasonal promotion, so the 10% applies whenever you order on full-price stock rather than only during a sale window. It does not stack on items already reduced.
What It Actually Costs
Prices read off their own site and checked . They are HardCore's prices, not ours, and they move, so treat this as a guide rather than a quote. These are their best sellers — not a shopping list.
- Hardcore Labs RAD140 (Testolone) — €46.99
- Hardcore Labs MK677 (Ibutamoren) — €44.99, reduced from €49.99
- Thoroughbred Labs BPC 157 — €49.99
- Thoroughbred Labs TB500 — €54.99
- Hardcore Labs SLU-PP-332 — €59.99 for the smaller size, down from €74.99, and €79.99 for the larger, down from €94.99
- Density Labs Enclomiphene — €64.99
- VitaBlue Methylene Blue 30ml — €39.99
- Amino Kings L-Carnitine liquid — €69.99
The bit a coupon site will not tell you: three of those are already reduced, and NNF10 does not stack on anything already cut. On the MK677 and on both SLU-PP-332 sizes you pay the sale price and the code does nothing at all.
And the bigger thing: most of that list is research compounds, and 10% off is not a reason to buy any of it. Read the next section before anything goes in a cart.
Why I Will Not Push the SARMs or the Peptides
Those lines are a large part of what sells here, so calling this a pre-workout shop would be dishonest. Selling past them would be worse.
We write these compounds up ourselves, and the write-ups are not flattering. Our RAD-140 (Testolone) research guide exists because there has been exactly one first-in-human trial of it, ever — 22 patients with metastatic breast cancer, phase 1. The two commonest adverse events in that trial were raised liver enzymes: AST in 59.1% of those patients and ALT in 45.5%. On top of that, published case reports of drug-induced liver injury have appeared every year since 2020. No trial has ever measured what it does to muscle in a healthy person, because that trial has not been run.
MK-677 (ibutamoren) is not even a SARM, and it is not approved anywhere, for anything.
So, plainly: the code works on those products, because it works across the shop. That is not us telling you to use them. The human evidence is thin, our own pages say so, and "there is 10% off" is the worst reason anyone ever took anything.
If you want the research instead of the sales copy, it is here and it is free: our peptide research library and what SARMs actually are, and where Ireland stands on them. Educational only — no doses, no protocols, no telling you what to put in your body.
Is HardCore Worth It?
For it: for the ordinary half of the shop — pre-workouts, aminos, carnitine, nootropics, the herbal test-support formulas — it does the job. Stock leaves an Irish warehouse, delivery is €5.99 and lands in one to two working days, and it is free over €100. A problem does not have to cross the water. NNF10 has no expiry date either, so the 10% is there on full-price stock any day of the year rather than only in a sale window.
Against it: a lot of the range is research compounds sold like consumer products, and that is the part I would leave alone. Several of the best sellers sit permanently reduced, which quietly means the code is worth nothing on them. And nothing on their site tells you where the company actually is beyond "Northern Ireland".
Who I would not send here: anyone new to this. If your calories and protein are not sorted, none of it matters, and the SARM shelf is the last place a beginner should be looking.
Where They Are
Northern Ireland, in their own words: "Northern Ireland's fastest growing supplier of health and sports supplements" and "a leading supplement company based in Northern Ireland". Worth being straight about the rest — no street address is published anywhere on their site, so there is nothing to walk into and no counter to bring a problem to. Delivery comes "from our Irish warehouse" at €5.99, one to two working days Monday to Friday by An Post or GLS, free over €100. Their footer also carries a "SARMs Locations" link, which is a page on their site rather than a shop you can visit.

- Pre-workouts and fat burners: the stimulant-heavy end of the market

Why This Page Exists
Worth saying plainly: I have been buying from HardCore 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: HardCore 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 HardCore Supplements discount code?
NNF10. It takes 10% off your order at hardcoresupplements.ie. Enter it in the discount code field at checkout.
How do I use the NNF10 code on hardcoresupplements.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 HardCore ship from?
An Irish warehouse. Delivery is €5.99, one to two working days Monday to Friday by An Post or GLS, and free on orders over €100. No street address is published anywhere on their site, so treat it as an online-only shop.
Do you recommend the SARMs and peptides HardCore sells?
No. The code applies across the shop because that is how the shop works, but we do not recommend buying research compounds on the strength of a discount. Our own RAD-140 and MK-677 research guides set out how thin the human evidence is.
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 HardCore 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 HardCore 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?
HardCore ships free on orders over €100. The 10% is taken off before that is worked out, so watch the total if you are close to the line.
Discount codes and delivery terms are set by HardCore Supplements and can change without notice. Details here reflect what their site said when this page was written.
