First-order codes at our top three shops, compared

Your first order at a new shop is usually your best shot at a big discount. Shops want you through the door, so welcome codes tend to be generous. But “first-order code” doesn’t automatically mean “best code” — at some of our partners, a sitewide code is actually bigger.

Here’s how the three partner shops compare, based on the codes on PeptDeals at the time of writing. Codes change, so always check the live coupon page before you order.

The quick comparison

Shop	Welcome code	Other codes a new customer can use
Nexo Research	25% off the first order, no minimum	PeptDeals-only 30% code (min. €100)
Europa-Peptide	15% off the first order	20% sitewide partner code
Peptid24	—	18% sitewide partner code, €10 off from €80

Three very different setups. Let’s go shop by shop.

Nexo Research: two strong options

Nexo Research is #1 in our ranking and has the most generous codes in our network. As a new customer you can choose between:

• 25% off your first order — no minimum order, new customers only, one use.
• 30% off with the PeptDeals-only code — only available on this site after email verification, minimum order €100, one use per customer.

So the rule is simple:

• Cart under €100? The 25% welcome code is your pick. On a €60 cart, that’s €15 off.
• Cart of €100 or more? The 30% code wins. On a €120 cart, that’s €36 off instead of €30.

Bonus: from €99, Nexo ships free across the EU. A cart that qualifies for the 30% code is usually close to free shipping too — see our guide on stacking codes with free shipping.

Europa-Peptide: the sitewide code beats the welcome code

Europa-Peptide has a classic 15% first-order code for new customers. But we also carry an exclusive 20% sitewide partner code for europa-peptide.de, one use per customer, with no minimum order.

For most first orders, that means the 20% code is the better choice — it’s bigger, and it isn’t limited to new customers. The welcome code makes sense mainly if you’ve already used the 20% code.

One more thing for first-timers: Europa-Peptide has look-alike competitors with very similar names. Our links always point to europa-peptide.de — check the address bar before you pay.

Peptid24: no welcome code, but a strong everyday one

Peptid24 doesn’t have a dedicated first-order code with us. What it does have:

• 18% off sitewide with our partner code, one use per customer.
• €10 off orders from €80.

Do the math once and you’ll see the 18% code wins whenever the €10 code is even allowed: at €80, 18% is €14.40. Combine that with Peptid24’s low €75 free-shipping line and the low entry prices (from €24.90), and it’s an easy shop to start small with.

How to choose your first shop

Price isn’t everything. Before you place a first order anywhere, it’s worth a quick look at the shop itself:

• Read the profile. Our pages for Nexo Research, Europa-Peptide and Peptid24 list what each shop publishes — and what it doesn’t.
• Ask for the COA. None of the three publishes lab reports that we could find. Ask support for the certificate of analysis of your batch before ordering.
• Check shipping. All three ship across the EU; Peptid24 ships from Germany.

Then let the cart decide:

• Small first cart (under €75): Nexo’s 25% welcome code is the biggest no-minimum discount we have.
• Medium cart (€75–€99): compare Nexo’s 25% with Peptid24’s 18% plus free shipping from €75.
• €100 and up: Nexo’s PeptDeals-only 30% code is the strongest number on the board.

Don’t waste your welcome code

Welcome codes are one-shot. A few habits help:

• Use them on an order you’d place anyway, not a test order of one cheap item.
• Check whether a sitewide code is bigger (as at Europa-Peptide) — then keep the welcome code for later.
• Unlock the code before you start shopping. We email you a copy, so it’s ready at checkout.

All of these codes are on our coupon page. Verify your email once and every one of them unlocks for 180 days — here’s how that works.
