Avellon Peptides Review
Registered Polish research peptide supplier shipping within the EU. Publishes full, uncropped Janoshik Analytical reports for most of its catalog, many of them commissioned by the independent directory ChemVerify rather than by the vendor itself.

The Verdict on Avellon Peptides
Avellon Peptides is a registered Polish company that ships within the EU and publishes an unusually broad set of laboratory reports: HPLC, LC-MS, endotoxin and heavy-metal results for most products. The reports we read are full Janoshik Analytical documents, several commissioned by the independent directory ChemVerify, which is a stronger signal than vendor-commissioned testing. The catch is in the numbers: no report names a batch, and the samples we checked measured slightly below the label and, in one case, below the vendor’s own ≥99% purity claim. Check the report for your product before ordering.
How Avellon Peptides Scores
Each criterion is scored independently out of 10. The star rating is the weighted average of these scores divided by two: lab transparency 30%, COA quality 20%, independent reputation 20%, shipping, catalog and value 10% each. Lab transparency is weighted most heavily, because a purity figure from an unnamed laboratory cannot be independently corroborated.
What We Found
Strengths
- Retatrutide (sold as RT-3) confirmed by blind screen. Two ChemVerify-commissioned Janoshik reports ran a blind GLP-1 test and identified retatrutide: 10.94 mg at 99.572% on a 10 mg vial (#217945, August 2026) and 22.57 mg at 99.706% on a 20 mg vial (#231721, September 2026). As with the other Avellon reports, the batch field is blank or Unknown.
- Legal entity confirmed: Avellon Peptides sp. z o.o., registered in Zielona Góra, Poland, verified in the Polish National Court Register (KRS 0001218785).
- Full, uncropped Janoshik reports with task number, client, manufacturer and verification key, published for most of the catalog and covering HPLC purity, LC-MS identity, endotoxins and heavy metals.
- Testing commissioned by a third party. The reports we read were ordered by ChemVerify, an independent directory, which reduces the risk of a vendor-selected sample.
- Publishes unfavourable results. The lab-reports page keeps reports online that fall short of the label or the vendor’s own purity claim (Epithalon #231741, TB-500 #237187) instead of removing them, so buyers can see the deviations for themselves.
- EU-domestic dispatch, so no customs or import duty exposure for researchers inside the European Union.
Weaknesses & caveats
- No batch numbers on the reports. The batch field is blank or “Unknown” on all three reports we read, so a result cannot be matched to the vial you receive.
- Measured content below label, and one purity result below the vendor claim. Epithalon 10 mg: 9.35 mg at 98.327% purity (Janoshik #231741, September 2026), below the ≥99% stated on the vendor’s lab page. TB-500 10 mg: 9.07 mg at 99.102% (#237187, October 2026). Small deviations are common in this market, but they contradict an overfill claim we previously listed for this vendor, which we have removed.
- Very limited independent community footprint. We found little substantive third-party discussion of this vendor beyond directory listings, and no verifiable third-party review profile.
Lab Testing & COA Transparency
The single most useful question about any peptide vendor: can the purity claim be checked by someone other than the vendor?
| Testing lab publicly named | Yes — Janoshik Analytical (reports commissioned by ChemVerify) |
|---|---|
| COA practice | A public lab-reports page lists HPLC, LC-MS, endotoxin and heavy-metal reports per product. The three Janoshik reports we read in full (tasks #231741, #237179, #237187) show the complete header with task number, client, sample and manufacturer “Avellon”, plus a verification key. The client on all three is ChemVerify, not the vendor. The batch field is blank or “Unknown” on every report we read, so a report cannot be tied to the vial a customer receives. |
| Shipping | Ships from within the European Union (Poland), avoiding customs and import duty for EU researchers. |
Claims We Could Not Verify
Avellon Peptides makes the following claims about itself. We found no independent corroboration for them. That does not make them false, but they rest on the vendor's word alone.
- The Janoshik verification keys. Janoshik's portal blocks automated access, so we read the reports but could not confirm the keys at source ourselves. Check the key for your product at janoshik.com/verify.
- In-house manufacturing in Europe. Stated by the vendor in correspondence (October 2026); not independently confirmed.
- Regulatory reasons for the GLP-1 range. At our catalog check on 17 October 2026 the shop listed 21 products, with retatrutide (RT-3) as its only incretin compound and no tirzepatide or semaglutide. Avellon states (October 2026) that it deliberately does not sell compounds that may fall under medicinal-product law.

Yes. Code BIOHACKTESTED gives 10% OFF at checkout on Avellon Peptides. The discount does not change our rating: the score above is based on lab transparency, COA quality and third-party reputation only.
QDoes Avellon Peptides provide Certificates of Analysis?
A public lab-reports page lists HPLC, LC-MS, endotoxin and heavy-metal reports per product. The three Janoshik reports we read in full (tasks #231741, #237179, #237187) show the complete header with task number, client, sample and manufacturer “Avellon”, plus a verification key. The client on all three is ChemVerify, not the vendor. The batch field is blank or “Unknown” on every report we read, so a report cannot be tied to the vial a customer receives. The testing laboratory is publicly identified as Janoshik Analytical (reports commissioned by ChemVerify), which allows the documentation to be traced to a named third party.
QWhat are the main complaints about Avellon Peptides?
