Tickets on CodeVial carry a couple of labels: a violet Exclusive or CodeVial only tag, and a stub that says either “Members drop” or “Public code”. This post explains what each one means, how our partner deals work, and where the limits are.
Who our partners are
CodeVial works with three affiliate partners. They hold the top three spots in our ranking, in this order:
- Nexo Research — nexoresearch.shop
- Europa-Peptide — europa-peptide.de
- Peptid24 — peptid24.de
We do not put badges on them. Instead, the affiliate note in the footer, on the rankings page and in our methodology says plainly that partnerships can influence placement. Every other shop is ranked after them by score.
What “partner” means in practice
Two things, and we will not dress either of them up:
- We earn a commission when you buy from a partner through our links. It costs you nothing extra.
- Partners give us codes. That is why every code on CodeVial comes from a partner shop, and why the strongest codes in the club are partner codes.
What it does not mean: we do not invent facts for partners. If a partner does not publish something — lab reports, payment methods, a refund policy — our facts table says “not published”, exactly as it does for everyone else. Nexo Research’s own page lists “lab reports are not public yet” among its cons.
The three labels, decoded
Exclusive (violet tag) — a partner code meant for our members rather than the shop’s general audience. Examples right now: Europa-Peptide’s 20% sitewide code and Peptid24’s 18% sitewide code.
CodeVial only (violet tag) — a code that exists on this site and nowhere else, not even on the other sites in our network. The current one is Nexo Research’s 30% members code (minimum order €100). It is our drop of the week for a reason.
Public code (stub label) — a code that is not exclusive to us. It might be the shop’s own welcome offer — Europa-Peptide’s 15% first-order code, for example. We still list it, because a working public code is better than none.
Why exclusive codes are bigger
Shops are generous with codes that reach real buyers and stingy with codes that end up on aggregator farms. An exclusive code is a bet by the shop that a smaller, verified audience will use it properly. That is the whole reason exclusive codes tend to beat public ones — and the reason we gate them behind a verified email.
Nexo Research currently gives us the strongest set: the CodeVial-only 30% code, a 25% first-order code, 20% off from €150, free EU shipping with no minimum and a 3-for-2 bundle code.
What about shops that are not partners?
We list them, score them and compare them, with the same criteria and the same “not published” rule. What we cannot do is give you a code for them, because no one has given us one. Their pages say so plainly — “No code for this shop right now” — and link to the shop’s own domain or, where we could not confirm one, to its public listing.
How partner status affects rankings
Partners are pinned first, in a fixed order. We say so openly instead of hiding it inside a score. The five-criteria scores themselves are editorial estimates from each shop’s public information. For the full method, see how we rate.
A quick checklist before you check out
- Is the code exclusive or CodeVial-only? Check the violet tag.
- Does your cart meet the minimum? Check MIN on the ticket.
- Are you on the right domain? Our post on copycat shop domains has a 30-second check.
Research use only
The shops sell products for laboratory research use only. We compare vendors and their codes; nothing here is medical advice.
