Most-Ordered Research Peptides in the EU: Ranking by Country (2026)

How was this ranking built, and what is left out?

The ranking uses peptidesdirect.io fulfilled orders from 2026-03-21 to 2026-09-12, with compounds ranked by orders containing the compound. The included statuses are delivered, shipped, returned and refunded; cancelled and unpaid orders are excluded. “Fulfilled” is the snapshot's defined status grouping, so the inclusion of returned and refunded orders matters when reading the results. [P1, snapshot]

The unit is an order containing a compound, rather than the quantity of vials in that order. Accessories, including bacteriostatic water and kits, are outside the ranking. Compounds no longer listed are also excluded. This makes the table a ranking of eligible compounds within the stated snapshot, with the same exclusions applied throughout. [P1, snapshot]

Equal underlying values share a rank. The published tables disclose positions and ties, while the accompanying text describes only the relative gaps documented in the snapshot. Country tables use shipping destinations. They describe ordering at this shop and do not stand for the wider European market. [P1, snapshot, country rankings and absence statements]

Which research peptides are ordered most often overall?

Retatrutide ranks first overall, followed by GHK-Cu and BPC-157. The table below reproduces the snapshot's overall positions and compound labels. [P1, overall ranking]

The top three are clearly separated from each other and from the rest: each step down is a clear gap. Positions 4 to 6 lie close together, as do positions 7 and 8. Retatrutide alone accounts for a larger share of orders than positions 4 to 8 combined. These are the snapshot's stated relative comparisons; the spacing between rank numbers does not itself describe the size of a gap. [P1, overall ranking]

How do Germany, Spain, France and Sweden differ?

Retatrutide leads every listed country, while the positions below it vary by destination. GHK-Cu ranks second in three of four country lists. The tables stop at the country-specific cut-offs supplied with the snapshot, preserving Germany's shared rank. [P1, country rankings]

Germany (DE), top 5:

Positions 4 are a tie. Neither blend is placed ahead of the other. [P1, country rankings]

Spain (ES), top 5:

Spain is the only listed country with Thymosin Alpha-1 and MOTS-c in the top five. [P1, country rankings]

France (FR), top 4:

France is the only country list containing tesamorelin and KPV. [P1, country rankings]

Sweden (SE), top 3:

Sweden is the only list where the CJC-1295/Ipamorelin blend ranks second. Other EU countries have too few fulfilled orders for a robust ranking and are not listed. The differing cut-offs limit the comparisons: an omitted compound has no published position in that country table. [P1, country rankings]

How do orders reach the shop?

Direct traffic leads by a wide margin in the recorded first-touch channel ranking. Attribution began when the shop's own attribution went live, so this table covers the more recent part of the snapshot rather than its full date range. [P1, order channels]

Orders attributed to AI assistants and search engines are practically level, both far behind direct. Campaigns, referral sites and email together are a small remainder. The direct label includes unattributed orders as well as typed URLs and bookmarks; it therefore does not identify a known discovery route for every order assigned to it. [P1, order channels]

What can a ranking like this not tell you?

This ranking cannot establish efficacy, tolerability, quality or suitability for a research project. Its subject is ordering behavior at this EU shop; this snapshot contains no comparison with other shops. A high position is not a finding about what a compound does. [P1, snapshot and absence statements]

The snapshot dates define the period being described; the ranking is refreshed each quarter. Each reading belongs with those dates, the inclusion rules and the country cut-offs. The table positions provide no basis for a protocol or a recommendation to select or combine compounds. [P1, snapshot and legal notes]

Products mentioned

Retatrutidemetabolic

Retatrutide (LY3437943) is a synthetic 39-amino-acid peptide that acts on three receptors at once: GLP-1, GIP and glucagon. Supplied as a lyophilized powder for in-vitro research, with a batch-specific third-party certificate of analysis.
