Who runs this page, how it earns money, and how the scores are worked out.
Who runs this site
Clear-Labs is run by [Operator name], [Street and number], [Postcode and city], [Country].
How the ranking is ordered
Place 1 is our pick. Ziffer is at the top because we put it there, not because it won a rating. Its card says so.
No score for place 1. Ziffer gets no points and is not part of the scored comparison. Its card presents the shop; it is not a rating.
Places 2 to 7 follow the score. The levels are fixed and listed below. The cards show no overall score; the level for each criterion, with its source, is under “Strengths, weaknesses and sources” on each card, so every assignment can be checked.
How we earn
We receive no money from the shops in places 2 to 7. The links to them are not partner links, and none of these shops paid for a place, a level or a mention.
The link to Ziffer carries a parameter so the shop can count visits from this page.
What we do not claim
We made no test purchases and commissioned no lab analyses.
This is not an independent test institute, and not an editorial team without an interest of its own.
There are no customer quotes, sales figures or seals on this site, because we have none we could substantiate.
Why the EU
Clear-Labs looks at every shop from the point of view of a buyer in the EU: shipping within the EU, end prices in euros as displayed when requested from Austria, and the company details a shop discloses. Where a shop sits outside the EU or does not name its seat, its card says so.
How we rated
On 11 October 2026 we read each shop’s public pages: home page, product pages, shipping and payment pages, imprint, terms and the certificate archive, plus the Trustpilot profile where it could be loaded. Each fact was matched to a fixed level from 0 to 5. All six criteria count equally.
The overall score is the mean of the rated criteria, rounded to one decimal. For example: 5 + 5 + 5 + 4 + 4 + 4 = 27 points, divided by 6 criteria, gives 4.5. Where two shops tie, the one with more points for certificates comes first, then the alphabet.

5On average at least 15% below the median
45 to 15% below the median
3Within 5% of the median
25 to 20% above the median
1More than 20% above the median
–Fewer than two comparable items: not rated; the overall score is the mean of the other criteria
Price basis
The price points are computed from this table. It lists 9 items that at least two shops carry in the same size. For each item we take the median of all recorded prices, then average, per shop, how far its prices are from that median. “From” prices without a size and catalogue abbreviations without a plain name are left out. A shop with fewer than two comparable items gets no price points; that applies to CertaPeptides and Adria Science.
These are end prices as displayed on 11 October 2026 when requested from Austria. VAT can differ by delivery country, and shipping is not included. Marked is the lowest price in each row.
CertaPeptides, BPC-157 5 mg: shown as reduced, struck-through price €43.99.
ELYVERA, Retatrutide 10 mg: listed as “Triple Receptor Agonist (Reta)”.
Limits of this comparison
A snapshot. Shops change prices, payment options and terms all the time. The date is shown next to every fact.
Statements, not measurements. We cannot judge whether a batch matches its certificate. We rate whether the certificate exists and whether you can cross-check it.
The EU is not one price list. Shipping costs, delivery times and VAT differ by country. Where a shop prices by country, the basis text names examples.
Trustpilot. Three profiles could not be loaded on the reference date. The basis text says what the level rests on.
Older facts. Where we rely on our market survey of 21 August 2026, the basis text says so.
No legal advice. Whether buying a particular substance is permitted in your country is not answered here.
Corrections
If a fact is wrong or out of date, write to [email], ideally with a link to the page that shows the correct one. That applies to the shops themselves as well. We check the source and correct it.
